Adults older than 50 years who report experiencing persistently high levels of loneliness have a 56% increased risk for stroke, a new study showed.

The increased stroke risk did not apply to individuals who reported experiencing situational loneliness, a finding that investigators believe bolsters the hypothesis that chronic loneliness is driving the association.

“Our findings suggest that individuals who experience chronic loneliness are at higher risk for incident stroke,” lead investigator Yenee Soh, ScD, research associate of social and behavioral sciences in the Harvard T.H. Chan School of Public Health, Boston, told this news organization. “It is important to routinely assess loneliness, as the consequences may be worse if unidentified and/or ignored.”

The findings were published online in eClinicalMedicine.
 

Significant, Chronic Health Consequences

Exacerbated by the COVID-19 pandemic, loneliness is at an all-time high. A 2023 Surgeon General’s report highlighted the fact that loneliness and social isolation are linked to significant and chronic health consequences.

Previous research has linked loneliness to cardiovascular disease, yet few studies have examined the association between loneliness and stroke risk. The current study is one of the first to examine the association between changes in loneliness and stroke risk over time.

Using data from the 2006-2018 Health and Retirement Study, researchers assessed the link between loneliness and incident stroke over time. Between 2006 and 2008, 12,161 study participants, who were all older than 50 years with no history of stroke, responded to questions from the Revised UCLA Loneliness Scale. From these responses, researchers created summary loneliness scores.

Four years later, from 2010 to 2012, the 8936 remaining study participants responded to the same 20 questions again. Based on loneliness scores across the two time points, participants were divided into four groups:

• Consistently low (those who scored low on the loneliness scale at both baseline and follow-up).
• Remitting (those who scored high at baseline and low at follow-up).
• Recent onset (those who scored low at baseline and high at follow-up).
• Consistently high (those who scored high at both baseline and follow-up).

Incident stroke was determined by participant report and medical record data.

Among participants whose loneliness was measured at baseline only, 1237 strokes occurred during the 2006-2018 follow-up period. Among those who provided two loneliness assessments over time, 601 strokes occurred during the follow-up period.

Even after adjusting for social isolation, depressive symptoms, physical activity, body mass index, and other health conditions, investigators found that participants who reported being lonely at baseline only had a 25% increased stroke risk, compared with those who did not report being lonely at baseline (hazard ratio [HR], 1.25; 95% confidence interval (CI), 1.06-1.47).

Participants who reported having consistently high loneliness across both time points had a 56% increased risk for incident stroke vs those who did not report loneliness at both time points after adjusting for social isolation and depression (HR, 1.56; 95% CI, 1.11-2.18).

The researchers did not investigate any of the underlying issues that may contribute to the association between loneliness and stroke risk, but speculated there may be physiological factors at play. These could include inflammation caused by increased hypothalamic pituitary-adrenocortical activity, behavioral factors such as poor medication adherence, smoking and/or alcohol use, and psychosocial issues.

Those who experience chronic loneliness may represent individuals that are unable to develop or maintain satisfying social relationships, which may result in longer-term interpersonal difficulties, Dr. Soh noted.

“Since loneliness is a highly subjective experience, seeking help to address and intervene to address a patient’s specific personal needs is important. It’s important to distinguish loneliness from social isolation,” said Dr. Soh.

She added that “by screening for loneliness and providing care or referring patients to relevant behavioral healthcare providers, clinicians can play a crucial role in addressing loneliness and its associated health risks early on to help reduce the population burden of loneliness.”
 

Progressive Research

Commenting on the findings for this news organization, Elaine Jones, MD, medical director of Access TeleCare, who was not involved in the research, applauded the investigators for “advancing the topic by looking at the chronicity aspect of loneliness.”

She said more research is needed to investigate loneliness as a stroke risk factor and noted that there may be something inherently different among respondents who reported loneliness at both study time points.

“Personality types may play a role here. We know people with positive attitudes and outlooks can do better in challenging health situations than people who are negative in their attitudes, regardless of depression. Perhaps those who feel lonely initially decided to do something about it and join groups, take up a hobby, or re-engage with family or friends. Perhaps the people who are chronically lonely don’t, or can’t, do this,” Dr. Jones said.

Chronic loneliness can cause stress, she added, “and we know that stress chemicals and hormones can be harmful to health over long durations of time.”

The study was funded by the National Institute on Aging. There were no conflicts of interest noted.

Halifax, Nova Scotia; American Samoa; Queens, New York; Lansing, Michigan; Gurugram, India. I often ask patients where they’re from. Practicing in San Diego, the answers are a geography lesson. People from around the world come here. I sometimes add the more interesting question: How’d you end up here? Many took the three highways to San Diego: the Navy, the defense industry (like General Dynamics), or followed a partner. My Queens patient had a better answer: Super Bowl XXII. On Sunday, Jan. 31st, 1988, the Redskins played the Broncos in San Diego. John Elway and the Broncos lost, but it didn’t matter. “I was scrapin’ the ice off my windshield that Monday morning when I thought, that’s it. I’m done! I drove to the garage where I worked and quit on the spot. Then I drove home and packed my bags.”

In a paper on how to make life decisions, this guy would be Exhibit A: “Don’t overthink it.” That approach might not be suitable for everyone, or for every decision. It might actually be an example of how not to make life decisions (more on that later). But, is there a best way to go about making big life decisions?

The first treatise on this subject was a paper by one Franklin, Ben in 1772. Providing advice to a friend on how to make a career decision, Franklin argued: “My way is to divide half a sheet of paper by a line into two columns; writing over the one Pro and over the other Con.” This “moral algebra” as he called it was a framework to put rigor to a messy, organic problem.

The flaw in this method is that in the end you have two lists. Then what? Do the length of the lists decide? What if some factors are more important? Well, let’s add tools to help. You could use a spreadsheet and assign weights to each variable. Then sum the values and choose based on that. So if “not scraping ice off your windshield” is twice as important as “doubling your rent,” then you’ve got your answer. But what if you aren’t good at estimating how important things are? Actually, most of us are pretty awful at assigning weights to life variables – having bags of money is the consummate example. Seems important, but because of habituation, it turns out to not be sustainable. Note Exhibit B, our wealthy neighbor who owns a Lambo and G-Wagen (AMG squared, of course), who just parked a Cybertruck in his driveway. Realizing the risk of depending on peoples’ flawed judgment, companies instead use statistical modeling called bootstrap aggregating to “vote” on the weights for variables in a prediction. If you aren’t sure how important a new Rivian or walking to the beach would be, a model can answer that for you! It’s a bit disconcerting, I know. I mean, how can a model know what we’d like? Wait, isn’t that how Netflix picks stuff for you? Exactly.

Ok, so why don’t we just ask our friendly personal AI? “OK, ChatGPT, given what you know about me, where can I have it all?” Alas, here we slam into a glass wall. It seems the answer is out there but even our life-changing magical AI tools fail us. Mathematically, it is impossible to have it all. An illustrative example of this is called the economic “impossible trinity problem.” Even the most sophisticated algorithm cannot find an optional solution to some trinities such as fixed foreign exchange rate, free capital movement, and an independent monetary policy. Economists have concluded you must trade off one to have the other two. Impossible trinities are common in economics and in life. Armistead Maupin in his “Tales of the City” codifies it as Mona’s Law, the essence of which is: You cannot have the perfect job, the perfect partner, and the perfect house at the same time. (See Exhibit C, one Tom Brady).

This brings me to my final point, hard decisions are matters of the heart and experiencing life is the best way to understand its beautiful chaos. If making rash judgments is ill-advised and using technology cannot solve all problems (try asking your AI buddy for the square root of 2 as a fraction) what tools can we use? Maybe try reading more novels. They allow us to experience multiple lifetimes in a short time, which is what we need to learn what matters. Reading Dorothea’s choice at the end of “Middlemarch” is a nice example. Should she give up Lowick Manor and marry the penniless Ladislaw or keep it and use her wealth to help others? Seeing her struggle helps us understand how to answer questions like: Should I give up my academic practice or marry that guy or move to Texas? These cannot be reduced to arithmetic. The only way to know is to know as much of life as possible.

My last visit with my Queens patient was our last together. He’s divorced and moving from San Diego to Gallatin, Tennessee. “I’ve paid my last taxes to California, Doc. I decided that’s it, I’m done!” Perhaps he should have read “The Grapes of Wrath” before he set out for California in the first place.

The Centers for Medicare & Medicaid Services (CMS) has announced the conclusion of a program that provided billions in early Medicare payments to those affected by the Change Healthcare/UnitedHealth Group cyberattack last winter. The Accelerated and Advance Payment program, which began in early March to assist hospitals and practices facing significant reimbursement delays, will stop accepting applications after July 12, 2024.

CMS reported that the program advanced more than $2.55 billion in Medicare payments to > 4200 Part A providers, including hospitals, and more than $717.18 million in payments to Part B suppliers such as physicians, nonphysician practitioners, and durable medical equipment suppliers.

According to CMS, the Medicare billing system is now functioning properly, and 96% of the early payments have been recovered. The advances were to represent ≤ 30 days of typical claims payments in a 3-month period of 2023, with full repayment expected within 90 days through “automatic recoupment from Medicare claims” — no extensions allowed.

The agency took a victory lap regarding its response. “In the face of one of the most widespread cyberattacks on the US health care industry, CMS promptly took action to get providers and suppliers access to the funds they needed to continue providing patients with vital care,” CMS Administrator Chiquita Brooks-LaSure said in a statement. “Our efforts helped minimize the disruptive fallout from this incident, and we will remain vigilant to be ready to address future events.”

Ongoing Concerns from Health Care Organizations

Ben Teicher, an American Hospital Association spokesman, said that the organization hopes that CMS will be responsive if there’s more need for action after the advance payment program expires. The organization represents about 5000 hospitals, health care systems, and other providers.

“Our members report that the aftereffects of this event will likely be felt throughout the remainder of the year,” he said. According to Teicher, hospitals remain concerned about their ability to process claims and appeal denials, the safety of reconnecting to cyber services, and access to information needed to bill patients and reconcile payments.

In addition, hospitals are concerned about “financial support to mitigate the considerable costs incurred as a result of the cyberattack,” he said.

Charlene MacDonald, executive vice-president of public affairs at the Federation of American Hospitals, which represents more than 1000 for-profit hospitals, sent a statement to this news organization that said some providers “are still feeling the effects of care denials and delays caused by insurer inaction.

“We appreciate that the Administration acted within its authority to support providers during this unprecedented crisis and blunt these devastating impacts, especially because a vast majority of managed care companies failed to step up to the plate,” she said. “It is now time to shift our focus to holding plans accountable for using tactics to delay and deny needed patient care.”

Cyberattack Impact and Response

The ransom-based cyberattack against Change Healthcare/UnitedHealth Group targeted an electronic data interchange clearing house processing payer reimbursement systems, disrupting cash flows at hospitals and medical practices, and affecting patient access to prescriptions and life-saving therapy.

Change Healthcare — part of the UnitedHealth Group subsidiary Optum — processes half of all medical claims, according to a Department of Justice lawsuit. The American Hospital Association described the cyberattack as “the most significant and consequential incident of its kind” in US history.

By late March, UnitedHealth Group said nearly all medical and pharmacy claims were processing properly, while a deputy secretary of the US Department of Health & Human Services told clinicians that officials were focusing on the last group of clinicians who were facing cash-flow problems.

Still, a senior advisor with CMS told providers at that time that “we have heard from so many providers over the last several weeks who are really struggling to make ends meet right now or who are worried that they will not be able to make payroll in the weeks to come.”

The Centers for Medicare & Medicaid Services (CMS) has announced the conclusion of a program that provided billions in early Medicare payments to those affected by the Change Healthcare/UnitedHealth Group cyberattack last winter. The Accelerated and Advance Payment program, which began in early March to assist hospitals and practices facing significant reimbursement delays, will stop accepting applications after July 12, 2024.

CMS reported that the program advanced more than $2.55 billion in Medicare payments to > 4200 Part A providers, including hospitals, and more than $717.18 million in payments to Part B suppliers such as physicians, nonphysician practitioners, and durable medical equipment suppliers.

According to CMS, the Medicare billing system is now functioning properly, and 96% of the early payments have been recovered. The advances were to represent ≤ 30 days of typical claims payments in a 3-month period of 2023, with full repayment expected within 90 days through “automatic recoupment from Medicare claims” — no extensions allowed.

The agency took a victory lap regarding its response. “In the face of one of the most widespread cyberattacks on the US health care industry, CMS promptly took action to get providers and suppliers access to the funds they needed to continue providing patients with vital care,” CMS Administrator Chiquita Brooks-LaSure said in a statement. “Our efforts helped minimize the disruptive fallout from this incident, and we will remain vigilant to be ready to address future events.”

Ongoing Concerns from Health Care Organizations

Ben Teicher, an American Hospital Association spokesman, said that the organization hopes that CMS will be responsive if there’s more need for action after the advance payment program expires. The organization represents about 5000 hospitals, health care systems, and other providers.

“Our members report that the aftereffects of this event will likely be felt throughout the remainder of the year,” he said. According to Teicher, hospitals remain concerned about their ability to process claims and appeal denials, the safety of reconnecting to cyber services, and access to information needed to bill patients and reconcile payments.

In addition, hospitals are concerned about “financial support to mitigate the considerable costs incurred as a result of the cyberattack,” he said.

Charlene MacDonald, executive vice-president of public affairs at the Federation of American Hospitals, which represents more than 1000 for-profit hospitals, sent a statement to this news organization that said some providers “are still feeling the effects of care denials and delays caused by insurer inaction.

“We appreciate that the Administration acted within its authority to support providers during this unprecedented crisis and blunt these devastating impacts, especially because a vast majority of managed care companies failed to step up to the plate,” she said. “It is now time to shift our focus to holding plans accountable for using tactics to delay and deny needed patient care.”

Andrew N. Wilner, MD: My guest today is Dr. Jose Merino, editor in chief of the Neurology family of journals and professor of neurology and co-vice chair of education at Georgetown University in Washington, DC.

Our program today is a follow-up of Dr. Merino’s presentation at the recent American Academy of Neurology meeting in Denver, Colorado. Along with two other panelists, Dr. Merino discussed the role of open-access publication and the dangers of predatory journals. 

Jose G. Merino, MD, MPhil: Thank you for having me here. It’s a pleasure.
 

Open Access Defined

Dr. Wilner: I remember when publication in neurology was pretty straightforward. It was either the green journal or the blue journal, but things have certainly changed. I think one topic that is not clear to everyone is this concept of open access. Could you define that for us? 

Dr. Merino: Sure. Open access is a mode of publication that fosters more open or accessible science. The idea of open access is that it combines two main elements. One is that the papers that are published become immediately available to anybody with an internet connection anywhere in the world without any restrictions. 

The second important element from open access, which makes it different from other models we can talk about, is the fact that the authors retain the copyright of their work, but they give the journal and readers a license to use, reproduce, and modify the content.

This is different, for example, from instances where we have funder mandates. For example, NIH papers have to become available 6 months after publication, so they’re available to everybody but not immediately. 

Then copyright is retained, in the case of NIH employees, for example, by the government or by the journals themselves. The two elements of open access, I think, are immediate access to the material and the fact that it’s published with a Creative Commons license. 

Dr. Wilner: I remember that when a journal article was published, say, in Neurology, if you didn’t have a subscription to Neurology, you went to the library that hopefully had a subscription.

If they didn’t have it, you would write to the author and say, “Hey, I heard you have this great paper because the abstract was out there. Could you send me a reprint?” Has that whole universe evaporated? 

Dr. Merino: It depends on how the paper is published. For example, in Neurology, some of the research we publish is open access. Basically, if you have an internet connection, you can access the paper.

That’s the case for papers published in our wholly open-access journals in the Neurology family like Neurology Neuroimmunology & Neuroinflammation, Neurology Genetics, or Neurology Education. 

For other papers that are published in Neurology, not under open access, there is a paywall. For some of them, the paywall comes down after a few months based on funder mandates and so on. As I was mentioning, the NIH-funded papers are available 6 months later. 

In the first 6 months, you may have to go to your library, and if your library has a subscription, you can download it directly. [This is also true for] those that always stay behind the paywall, where you have to have a subscription or your library has to have a subscription.
 

Is Pay to Publish a Red Flag?

Dr. Wilner: I’m a professional writer. With any luck, when I write something, I get paid to write it. There’s been a long tradition in academic medicine that when you submit an article to, say, Neurology, you don’t get paid as an author for the publication. Your reward is the honor of it being published. 

Neurology supports itself in various ways, including advertising and so on. That’s been the contract: free publication for work that merits it, and the journal survives on its own. 

With open access, one of the things that’s happened is that — and I’ve published open access myself — is that I get a notification that I need to pay to have my article that I’ve slaved over published. Explain that, please. 

Dr. Merino: This is the issue with open access. As I mentioned, the paper gets published. You’re giving the journal a license to publish it. You’re retaining the copyright of your work. That means that the journal cannot make money or support itself by just publishing open access because they belong to you. 

Typically, open-access journals are not in print and don’t have much in terms of advertising. The contract is you’re giving me a license to publish it, but it’s your journal, so you’re paying a fee for the journal expenses to basically produce your paper. That’s what’s happening with open access. 

That’s been recognized with many funders, for example, with NIH funding or many of the European funders, they’re including open-access fees as part of their funding for research. Now, of course, this doesn’t help if you’re not a funded researcher or if you’re a fellow who’s doing work and so on. 

Typically, most journals will have waived fees or lower fees for these situations. The reason for the open-access fee is the fact that you’re retaining the copyright. You’re not giving it to the journal who can then use it to generate its revenue for supporting itself, the editorial staff, and so on. 

Dr. Wilner: This idea of charging for publication has created a satellite business of what are called predatory journals. How does one know if the open-access journal that I’m submitting to is really just in the business of wanting my $300 or my $900 to get published? How do I know if that’s a reasonable place to publish? 
 

Predatory Journals

Dr. Merino: That’s a big challenge that has come with this whole idea of open access and the fact that now, many journals are online only, so you’re no longer seeing a physical copy. That has given rise to the predatory journals. 

The predatory journal, by definition, is a journal that claims to be open access. They’ll take your paper and publish it, but they don’t provide all the other services that you would typically expect from the fact that you’re paying an open-access fee. This includes getting appropriate peer review, production of the manuscript, and long-term curation and storage of the manuscript. 

Many predatory journals will take your open-access fee, accept any paper that you submit, regardless of the quality, because they’re charging the fees for that. They don’t send it to real peer review, and then in a few months, the journal disappears so there’s no way for anybody to actually find your paper anymore. 

There are certain checklists. Dr. David Moher at the University of Toronto has produced some work trying to help us identify predatory journals. 

One thing I typically suggest to people who ask me this question is: Have you ever heard of this journal before? Does the journal have a track record? How far back does the story of the journal go? Is it supported by a publisher that you know? Do you know anybody who has published there? Is it something you can easily access?

If in doubt, always ask your friendly medical librarian. There used to be lists that were kept in terms of predatory journals that were being constantly updated, but those had to be shut down. As far as I understand, there were legal issues in terms of how things got on that list. 

I think that overall, if you’ve heard of it, if it’s relevant, if it’s known in your field, and if your librarian knows it, it’s probably a good legitimate open-access journal. There are many very good legitimate open-access journals. 

I mentioned the two that we have in our family, but all the other major journals have their own open-access journal within their family. There are some, like BMC or PLOS, that are completely open-access and legitimate journals. 
 

Impact Factor

Dr. Wilner: What about impact factor? Many journals boast about their impact factor. I’m not sure how to interpret that number. 

Dr. Merino: Impact factor is very interesting. The impact factor was developed by medical librarians to try to identify the journals they should be subscribing to. It’s a measure of the average citations to an average paper in the journal. 

It doesn’t tell you about specific papers. It tells you, on average, how many of the papers in this journal get cited so many times. It’s calculated by the number of articles that were cited divided by the number of articles that were published. Journals that publish many papers, like Neurology, have a hard time bringing up their impact factor beyond a certain level. 

Similarly, very small journals with one or two very highly cited papers have a very high impact factor. It’s being used as a measure, perhaps inappropriately, of how good or how reputable a journal is. We all say we don’t care about journal impact factors, but we all know our journal impact factor and we used to know it to three decimals. Now, they changed the system, and there’s only one decimal point, which makes more sense. 

This is more important, for example, for authors when deciding where to submit papers. I know that in some countries, particularly in Europe, the impact factor of the journal where you publish has an impact on your promotion decisions. 

I would say what’s even more important than the impact factor, is to say, “Well, is this the journal that fits the scope of my paper? Is this the journal that reaches the audience that I want to reach when I write my paper?” 

There are some papers, for example, that are very influential. The impact factor just captures citations. There are some papers that are very influential that may not get cited very often. There may be papers that change clinical practice. 

If you read a paper that tells you that you should be changing how you treat your patients with myasthenia based on this paper, that may not get cited. It’s a very clinically focused paper, but it’s probably more impactful than one that gets cited very much in some respect, or they make it to public policy decisions, and so on. 

I think it’s important to look more at the audience and the journal scope when you submit your papers. 

Dr. Wilner: One other technical question. The journals also say they’re indexed in PubMed or Google Scholar. If I want to publish my paper and I want it indexed where the right people are going to find it, where does it need to be indexed? 

Dr. Merino: I grew up using Index Medicus, MedlinePlus, and the Library of Science. I still do. If I need to find something, I go to PubMed. Ideally, papers are listed in MedlinePlus or can be found in PubMed. They’re not the same thing, but you can find them through them. 

That would be an important thing. Nowadays, a lot more people are using Google Scholar or Google just to identify papers. It may be a little bit less relevant, but it’s still a measure of the quality of the journal before they get indexed in some of these. For example, if you get listed in MedlinePlus, it has gone through certain quality checks by the index itself to see whether they would accept the journal or not. That’s something you want to check.

Typically, most of the large journals or the journals you and I know about are listed in more than one place, right? They’re listed in Scopus and Web of Science. They’re listed in MedlinePlus and so on. Again, if you’re submitting your paper, go somewhere where you know the journal and you’ve heard about it. 

Dr. Wilner: I’m not going to ask you about artificial intelligence. We can do that another time. I want to ask something closer to me, which is this question of publish or perish. 

There seems to be, in academics, more emphasis on the number of papers that one has published rather than their quality. How does a younger academician or one who really needs to publish cope with that? 

Dr. Merino: Many people are writing up research that may not be relevant or that may not be high quality just because you need to have a long list of papers to get promoted, for example, if you’re an academician. 

Doug Altman, who was a very influential person in the field quality of not only medical statistics but also medical publishing, had the idea that we need less research, but we need better research. 

We often receive papers where you say, well, what’s the rationale behind the question in this paper? It’s like they had a large amount of data and were trying to squeeze as much as they could out of that. I think, as a young academician, the important thing to think about is whether it is an important question that matters to you and to the field, from whatever perspective, whether it’s going to advance research, advance clinical care, or have public policy implications. 

Is this one where the answer will be important no matter what the answer is? If you’re thinking of that, your work will be well recognized, people will know you, and you’ll get invited to collaborate. I think that’s the most important thing rather than just churning out a large number of papers. 

The productivity will come from the fact that you start by saying, let me ask something that’s really meaningful to me and to the field, with a good question and using strong research methodology. 

Dr. Wilner: Thanks for that, Dr. Merino. I think that’s very valuable for all of us. This has been a great discussion. Do you have any final comments before we wrap up? 

Dr. Merino: I want to encourage people to continue reading medical journals all the time and submitting to us, again, good research and important questions with robust methodology. That’s what we’re looking for in Neurology and most serious medical journals.

Is this one where the answer will be important no matter what the answer is? If you’re thinking of that, your work will be well recognized, people will know you, and you’ll get invited to collaborate. I think that’s the most important thing rather than just churning out a large number of papers. 

The productivity will come from the fact that you start by saying, let me ask something that’s really meaningful to me and to the field, with a good question and using strong research methodology. 

Dr. Wilner: Thanks for that, Dr. Merino. I think that’s very valuable for all of us. This has been a great discussion. Do you have any final comments before we wrap up? 

Dr. Merino: I want to encourage people to continue reading medical journals all the time and submitting to us, again, good research and important questions with robust methodology. That’s what we’re looking for in Neurology and most serious medical journals.

Andrew N. Wilner, MD: My guest today is Dr. Jose Merino, editor in chief of the Neurology family of journals and professor of neurology and co-vice chair of education at Georgetown University in Washington, DC.

Our program today is a follow-up of Dr. Merino’s presentation at the recent American Academy of Neurology meeting in Denver, Colorado. Along with two other panelists, Dr. Merino discussed the role of open-access publication and the dangers of predatory journals. 

Jose G. Merino, MD, MPhil: Thank you for having me here. It’s a pleasure.
 

Open Access Defined

Dr. Wilner: I remember when publication in neurology was pretty straightforward. It was either the green journal or the blue journal, but things have certainly changed. I think one topic that is not clear to everyone is this concept of open access. Could you define that for us? 

Dr. Merino: Sure. Open access is a mode of publication that fosters more open or accessible science. The idea of open access is that it combines two main elements. One is that the papers that are published become immediately available to anybody with an internet connection anywhere in the world without any restrictions. 

The second important element from open access, which makes it different from other models we can talk about, is the fact that the authors retain the copyright of their work, but they give the journal and readers a license to use, reproduce, and modify the content.

This is different, for example, from instances where we have funder mandates. For example, NIH papers have to become available 6 months after publication, so they’re available to everybody but not immediately. 

Then copyright is retained, in the case of NIH employees, for example, by the government or by the journals themselves. The two elements of open access, I think, are immediate access to the material and the fact that it’s published with a Creative Commons license. 

Dr. Wilner: I remember that when a journal article was published, say, in Neurology, if you didn’t have a subscription to Neurology, you went to the library that hopefully had a subscription.

If they didn’t have it, you would write to the author and say, “Hey, I heard you have this great paper because the abstract was out there. Could you send me a reprint?” Has that whole universe evaporated? 

Dr. Merino: It depends on how the paper is published. For example, in Neurology, some of the research we publish is open access. Basically, if you have an internet connection, you can access the paper.

That’s the case for papers published in our wholly open-access journals in the Neurology family like Neurology Neuroimmunology & Neuroinflammation, Neurology Genetics, or Neurology Education. 

For other papers that are published in Neurology, not under open access, there is a paywall. For some of them, the paywall comes down after a few months based on funder mandates and so on. As I was mentioning, the NIH-funded papers are available 6 months later. 

In the first 6 months, you may have to go to your library, and if your library has a subscription, you can download it directly. [This is also true for] those that always stay behind the paywall, where you have to have a subscription or your library has to have a subscription.
 

Is Pay to Publish a Red Flag?

Dr. Wilner: I’m a professional writer. With any luck, when I write something, I get paid to write it. There’s been a long tradition in academic medicine that when you submit an article to, say, Neurology, you don’t get paid as an author for the publication. Your reward is the honor of it being published. 

Neurology supports itself in various ways, including advertising and so on. That’s been the contract: free publication for work that merits it, and the journal survives on its own. 

With open access, one of the things that’s happened is that — and I’ve published open access myself — is that I get a notification that I need to pay to have my article that I’ve slaved over published. Explain that, please. 

Dr. Merino: This is the issue with open access. As I mentioned, the paper gets published. You’re giving the journal a license to publish it. You’re retaining the copyright of your work. That means that the journal cannot make money or support itself by just publishing open access because they belong to you. 

Typically, open-access journals are not in print and don’t have much in terms of advertising. The contract is you’re giving me a license to publish it, but it’s your journal, so you’re paying a fee for the journal expenses to basically produce your paper. That’s what’s happening with open access. 

That’s been recognized with many funders, for example, with NIH funding or many of the European funders, they’re including open-access fees as part of their funding for research. Now, of course, this doesn’t help if you’re not a funded researcher or if you’re a fellow who’s doing work and so on. 

Typically, most journals will have waived fees or lower fees for these situations. The reason for the open-access fee is the fact that you’re retaining the copyright. You’re not giving it to the journal who can then use it to generate its revenue for supporting itself, the editorial staff, and so on. 

Dr. Wilner: This idea of charging for publication has created a satellite business of what are called predatory journals. How does one know if the open-access journal that I’m submitting to is really just in the business of wanting my $300 or my $900 to get published? How do I know if that’s a reasonable place to publish? 
 

Predatory Journals

Dr. Merino: That’s a big challenge that has come with this whole idea of open access and the fact that now, many journals are online only, so you’re no longer seeing a physical copy. That has given rise to the predatory journals. 

The predatory journal, by definition, is a journal that claims to be open access. They’ll take your paper and publish it, but they don’t provide all the other services that you would typically expect from the fact that you’re paying an open-access fee. This includes getting appropriate peer review, production of the manuscript, and long-term curation and storage of the manuscript. 

Many predatory journals will take your open-access fee, accept any paper that you submit, regardless of the quality, because they’re charging the fees for that. They don’t send it to real peer review, and then in a few months, the journal disappears so there’s no way for anybody to actually find your paper anymore. 

There are certain checklists. Dr. David Moher at the University of Toronto has produced some work trying to help us identify predatory journals. 

One thing I typically suggest to people who ask me this question is: Have you ever heard of this journal before? Does the journal have a track record? How far back does the story of the journal go? Is it supported by a publisher that you know? Do you know anybody who has published there? Is it something you can easily access?

If in doubt, always ask your friendly medical librarian. There used to be lists that were kept in terms of predatory journals that were being constantly updated, but those had to be shut down. As far as I understand, there were legal issues in terms of how things got on that list. 

I think that overall, if you’ve heard of it, if it’s relevant, if it’s known in your field, and if your librarian knows it, it’s probably a good legitimate open-access journal. There are many very good legitimate open-access journals. 

I mentioned the two that we have in our family, but all the other major journals have their own open-access journal within their family. There are some, like BMC or PLOS, that are completely open-access and legitimate journals. 
 

Impact Factor

Dr. Wilner: What about impact factor? Many journals boast about their impact factor. I’m not sure how to interpret that number. 

Dr. Merino: Impact factor is very interesting. The impact factor was developed by medical librarians to try to identify the journals they should be subscribing to. It’s a measure of the average citations to an average paper in the journal. 

It doesn’t tell you about specific papers. It tells you, on average, how many of the papers in this journal get cited so many times. It’s calculated by the number of articles that were cited divided by the number of articles that were published. Journals that publish many papers, like Neurology, have a hard time bringing up their impact factor beyond a certain level. 

Similarly, very small journals with one or two very highly cited papers have a very high impact factor. It’s being used as a measure, perhaps inappropriately, of how good or how reputable a journal is. We all say we don’t care about journal impact factors, but we all know our journal impact factor and we used to know it to three decimals. Now, they changed the system, and there’s only one decimal point, which makes more sense. 

This is more important, for example, for authors when deciding where to submit papers. I know that in some countries, particularly in Europe, the impact factor of the journal where you publish has an impact on your promotion decisions. 

I would say what’s even more important than the impact factor, is to say, “Well, is this the journal that fits the scope of my paper? Is this the journal that reaches the audience that I want to reach when I write my paper?” 

There are some papers, for example, that are very influential. The impact factor just captures citations. There are some papers that are very influential that may not get cited very often. There may be papers that change clinical practice. 

If you read a paper that tells you that you should be changing how you treat your patients with myasthenia based on this paper, that may not get cited. It’s a very clinically focused paper, but it’s probably more impactful than one that gets cited very much in some respect, or they make it to public policy decisions, and so on. 

I think it’s important to look more at the audience and the journal scope when you submit your papers. 

Dr. Wilner: One other technical question. The journals also say they’re indexed in PubMed or Google Scholar. If I want to publish my paper and I want it indexed where the right people are going to find it, where does it need to be indexed? 

Dr. Merino: I grew up using Index Medicus, MedlinePlus, and the Library of Science. I still do. If I need to find something, I go to PubMed. Ideally, papers are listed in MedlinePlus or can be found in PubMed. They’re not the same thing, but you can find them through them. 

That would be an important thing. Nowadays, a lot more people are using Google Scholar or Google just to identify papers. It may be a little bit less relevant, but it’s still a measure of the quality of the journal before they get indexed in some of these. For example, if you get listed in MedlinePlus, it has gone through certain quality checks by the index itself to see whether they would accept the journal or not. That’s something you want to check.

Typically, most of the large journals or the journals you and I know about are listed in more than one place, right? They’re listed in Scopus and Web of Science. They’re listed in MedlinePlus and so on. Again, if you’re submitting your paper, go somewhere where you know the journal and you’ve heard about it. 

Dr. Wilner: I’m not going to ask you about artificial intelligence. We can do that another time. I want to ask something closer to me, which is this question of publish or perish. 

There seems to be, in academics, more emphasis on the number of papers that one has published rather than their quality. How does a younger academician or one who really needs to publish cope with that? 

Dr. Merino: Many people are writing up research that may not be relevant or that may not be high quality just because you need to have a long list of papers to get promoted, for example, if you’re an academician. 

Doug Altman, who was a very influential person in the field quality of not only medical statistics but also medical publishing, had the idea that we need less research, but we need better research. 

We often receive papers where you say, well, what’s the rationale behind the question in this paper? It’s like they had a large amount of data and were trying to squeeze as much as they could out of that. I think, as a young academician, the important thing to think about is whether it is an important question that matters to you and to the field, from whatever perspective, whether it’s going to advance research, advance clinical care, or have public policy implications. 

Is this one where the answer will be important no matter what the answer is? If you’re thinking of that, your work will be well recognized, people will know you, and you’ll get invited to collaborate. I think that’s the most important thing rather than just churning out a large number of papers. 

The productivity will come from the fact that you start by saying, let me ask something that’s really meaningful to me and to the field, with a good question and using strong research methodology.

In October 2023, Robert Card — a grenade instructor in the Army Reserve — shot and killed 18 people in Maine, before turning the gun on himself. As reported by The New York Times, his family said that he had become increasingly erratic and violent during the months before the rampage.

A postmortem conducted by the Chronic Traumatic Encephalopathy (CTE) Center at Boston University found “significant evidence of traumatic brain injuries” [TBIs] and “significant degeneration, axonal and myelin loss, inflammation, and small blood vessel injury” in the white matter, the center’s director, Ann McKee, MD, said in a press release. “These findings align with our previous studies on the effects of blast injury in humans and experimental models.”

Members of the military, such as Mr. Card, are exposed to blasts from repeated firing of heavy weapons not only during combat but also during training.

New data suggest that repeated blast exposure may impair the brain’s waste clearance system, leading to biomarker changes indicative of preclinical Alzheimer’s disease 20 years earlier than typical. A higher index of suspicion for dementia or Alzheimer’s disease may be warranted in patients with a history of blast exposure or subconcussive brain injury who present with cognitive issues, according to experts interviewed.

In 2022, the US Department of Defense (DOD) launched its Warfighter Brain Health Initiative with the aim of “optimizing service member brain health and countering traumatic brain injuries.”

In April 2024, the Blast Overpressure Safety Act was introduced in the Senate to require the DOD to enact better blast screening, tracking, prevention, and treatment. The DOD initiated 26 blast overpressure studies.

Heather Snyder, PhD, Alzheimer’s Association vice president of Medical and Scientific Relations, said that an important component of that research involves “the need to study the difference between TBI-caused dementia and dementia caused independently” and “the need to study biomarkers to better understand the long-term consequences of TBI.”
 

What Is the Underlying Biology?

Dr. Snyder was the lead author of a white paper produced by the Alzheimer’s Association in 2018 on military-related risk factors for Alzheimer’s disease and related dementias. “There is a lot of work trying to understand the effect of pure blast waves on the brain, as opposed to the actual impact of the injury,” she said.

The white paper speculated that blast exposure may be analogous to subconcussive brain injury in athletes where there are no obvious immediate clinical symptoms or neurological dysfunction but which can cause cumulative injury and functional impairment over time.

“We are also trying to understand the underlying biology around brain changes, such as accumulation of tau and amyloid and other specific markers related to brain changes in Alzheimer’s disease,” said Dr. Snyder, chair of the Peer Reviewed Alzheimer’s Research Program Programmatic Panel for Alzheimer’s Disease/Alzheimer’s Disease and Related Dementias and TBI.
 

Common Biomarker Signatures

A recent study in Neurology comparing 51 veterans with mild TBI (mTBI) with 85 veterans and civilians with no lifetime history of TBI is among the first to explore these biomarker changes in human beings.

“Our findings suggest that chronic neuropathologic processes associated with blast mTBI share properties in common with pathogenic processes that are precursors to Alzheimer’s disease onset,” said coauthor Elaine R. Peskind, MD, professor of psychiatry and behavioral sciences, University of Washington, Seattle.

The largely male participants were a mean age of 34 years and underwent standardized clinical and neuropsychological testing as well as lumbar puncture to collect cerebrospinal fluid (CSF). The mTBI group had experienced at least one war zone blast or combined blast/impact that met criteria for mTBI, but 91% had more than one blast mTBI, and the study took place over 13 years.

The researchers found that the mTBI group “had biomarker signatures in common with the earliest stages of Alzheimer’s disease,” said Dr. Peskind.

For example, at age 50, they had lower mean levels of CSF amyloid beta 42 (Abeta42), the earliest marker of brain parenchymal Abeta deposition, compared with the control group (154 pg/mL and 1864 pg/mL lower, respectively).

High CSF phosphorylated tau181 (p-tau181) and total tau are established biomarkers for Alzheimer’s disease. However, levels of these biomarkers remained “relatively constant with age” in participants with mTBI but were higher in older ages for the non-TBI group.

The mTBI group also showed worse cognitive performance at older ages (P < .08). Poorer verbal memory and verbal fluency performance were associated with lower CSF Abeta42 in older participants (P ≤ .05).

In Alzheimer’s disease, a reduction in CSF Abeta42 may occur up to 20 years before the onset of clinical symptoms, according to Dr. Peskind. “But what we don’t know from this study is what this means, as total tau protein and p-tau181 in the CSF were also low, which isn’t entirely typical in the picture of preclinical Alzheimer’s disease,” she said. However, changes in total tau and p-tau181 lag behind changes in Abeta42.
 

Is Impaired Clearance the Culprit?

Coauthor Jeffrey Iliff, PhD, professor, University of Washington Department of Psychiatry and Behavioral Sciences and University of Washington Department of Neurology, Seattle, elaborated.

“In the setting of Alzheimer’s disease, a signature of the disease is reduced CSF Abeta42, which is thought to reflect that much of the amyloid gets ‘stuck’ in the brain in the form of amyloid plaques,” he said. “There are usually higher levels of phosphorylated tau and total tau, which are thought to reflect the presence of tau tangles and degeneration of neurons in the brain. But in this study, all of those were lowered, which is not exactly an Alzheimer’s disease profile.”

Dr. Iliff, associate director for research, VA Northwest Mental Illness Research, Education, and Clinical Center at VA Puget Sound Health Care System, Seattle, suggested that the culprit may be impairment in the brain’s glymphatic system. “Recently described biological research supports [the concept of] clearance of waste out of the brain during sleep via the glymphatic system, with amyloid and tau being cleared from the brain interstitium during sleep.”

A recent hypothesis is that blast TBI impairs that process. “This is why we see less of those proteins in the CSF. They’re not being cleared, which might contribute downstream to the clumping up of protein in the brain,” he suggested.

The evidence base corroborating that hypothesis is in its infancy; however, new research conducted by Dr. Iliff and his colleagues sheds light on this potential mechanism.

In blast TBI, energy from the explosion and resulting overpressure wave are “transmitted through the brain, which causes tissues of different densities — such as gray and white matter — to accelerate at different rates,” according to Dr. Iliff. This results in the shearing and stretching of brain tissue, leading to a “diffuse pattern of tissue damage.”

It is known that blast TBI has clinical overlap and associations with posttraumatic stress disorder (PTSD), depression, and persistent neurobehavioral symptoms; that veterans with a history of TBI are more than twice as likely to die by suicide than veterans with no TBI history; and that TBI may increase the risk for Alzheimer’s disease and related dementing disorders, as well as CTE.

The missing link may be the glymphatic system — a “brain-wide network of perivascular pathways, along which CSF and interstitial fluid (ISF) exchange, supporting the clearance of interstitial solutes, including amyloid-beta.”

Dr. Iliff and his group previously found that glymphatic function is “markedly and chronically impaired” following impact TBI in mice and that this impairment is associated with the mislocalization of astroglial aquaporin 4 (AQP4), a water channel that lines perivascular spaces and plays a role in healthy glymphatic exchange.

In their new study, the researchers examined both the expression and the localization of AQP4 in the human postmortem frontal cortex and found “distinct laminar differences” in AQP4 expression following blast exposure. They observed similar changes as well as impairment of glymphatic function, which emerged 28 days following blast injury in a mouse model of repetitive blast mTBI.

And in a cohort of veterans with blast mTBI, blast exposure was found to be associated with an increased burden of frontal cortical MRI-visible perivascular spaces — a “putative neuroimaging marker” of glymphatic perivascular dysfunction.

The earlier Neurology study “showed impairment of biomarkers in the CSF, but the new study showed ‘why’ or ‘how’ these biomarkers are impaired, which is via impairment of the glymphatic clearance process,” Dr. Iliff explained.
 

Veterans Especially Vulnerable

Dr. Peskind, co-director of the VA Northwest Mental Illness Research, Education and Clinical Center, VA Puget Sound Health Care System, noted that while the veterans in the earlier study had at least one TBI, the average number was 20, and it was more common to have more than 50 mTBIs than to have a single one.

“These were highly exposed combat vets,” she said. “And that number doesn’t even account for subconcussive exposure to blasts, which now appear to cause detectable brain damage, even in the absence of a diagnosable TBI.”

The Maine shooter, Mr. Card, had not seen combat and was not assessed for TBI during a psychiatric hospitalization, according to The New York Times.

Dr. Peskind added that this type of blast damage is likely specific to individuals in the military. “It isn’t the sound that causes the damage,” she explained. “It’s the blast wave, the pressure wave, and there aren’t a lot of other occupations that have those types of occupational exposures.”

Dr. Snyder added that the majority of blast TBIs have been studied in military personnel, and she is not aware of studies that have looked at blast injuries in other industries, such as demolition or mining, to see if they have the same type of biologic consequences.

Dr. Snyder hopes that the researchers will follow the participants in the Neurology study and continue looking at specific markers related to Alzheimer’s disease brain changes. What the research so far shows “is that, at an earlier age, we’re starting to see those markers changing, suggesting that the underlying biology in people with mild blast TBI is similar to the underlying biology in Alzheimer’s disease as well.”

Michael Alosco, PhD, associate professor and vice chair of research, department of neurology, Boston University Chobanian & Avedisian School of Medicine, called the issue of blast exposure and TBI “a very complex and nuanced topic,” especially because TBI is “considered a risk factor of Alzheimer’s disease” and “different types of TBIs could trigger distinct pathophysiologic processes; however, the long-term impact of repetitive blast TBIs on neurodegenerative disease changes remains unknown.”

He coauthored an editorial on the earlier Neurology study that noted its limitations, such as a small sample size and lack of consideration of lifestyle and health factors but acknowledged that the “findings provide preliminary evidence that repetitive blast exposures might influence beta-amyloid accumulation.”
 

Clinical Implications

For Dr. Peskind, the “inflection point” was seeing lower CSF Abeta42, about 20 years earlier than ages 60 and 70, which is more typical in cognitively normal community volunteers.

But she described herself as “loath to say that veterans or service members have a 20-year acceleration of risk of Alzheimer’s disease,” adding, “I don’t want to scare the heck out of our service members of veterans.” Although “this is what we fear, we’re not ready to say it for sure yet because we need to do more work. Nevertheless, it does increase the index of suspicion.”

The clinical take-home messages are not unique to service members or veterans or people with a history of head injuries or a genetic predisposition to Alzheimer’s disease, she emphasized. “If anyone of any age or occupation comes in with cognitive issues, such as [impaired] memory or executive function, they deserve a workup for dementing disorders.” Frontotemporal dementia, for example, can present earlier than Alzheimer’s disease typically does.

Common comorbidities with TBI are PTSD and obstructive sleep apnea (OSA), which can also cause cognitive issues and are also risk factors for dementia.

Dr. Iliff agreed. “If you see a veteran with a history of PTSD, a history of blast TBI, and a history of OSA or some combination of those three, I recommend having a higher index of suspicion [for potential dementia] than for an average person without any of these, even at a younger age than one would ordinarily expect.”

Of all of these factors, the only truly directly modifiable one is sleep disruption, including that caused by OSA or sleep disorders related to PTSD, he added. “Epidemiologic data suggest a connection particularly between midlife sleep disruption and the risk of dementia and Alzheimer’s disease, and so it’s worth thinking about sleep as a modifiable risk factor even as early as the 40s and 50s, whether the patient is or isn’t a veteran.”

Dr. Peskind recommended asking patients, “Do they snore? Do they thrash about during sleep? Do they have trauma nightmares? This will inform the type of intervention required.”

Dr. Alosco added that there is no known “safe” threshold of exposure to blasts, and that thresholds are “unclear, particularly at the individual level.” In American football, there is a dose-response relationship between years of play and risk for later-life neurological disorder. “The best way to mitigate risk is to limit cumulative exposure,” he said.

The study by Li and colleagues was funded by grant funding from the Department of Veterans Affairs Rehabilitation Research and Development Service and the University of Washington Friends of Alzheimer’s Research. Other sources of funding to individual researchers are listed in the original paper. The study by Braun and colleagues was supported by the National Heart, Lung and Blood Institute; the Department of Veterans Affairs Rehabilitation Research and Development Service; and the National Institute on Aging.

“In the setting of Alzheimer’s disease, a signature of the disease is reduced CSF Abeta42, which is thought to reflect that much of the amyloid gets ‘stuck’ in the brain in the form of amyloid plaques,” he said. “There are usually higher levels of phosphorylated tau and total tau, which are thought to reflect the presence of tau tangles and degeneration of neurons in the brain. But in this study, all of those were lowered, which is not exactly an Alzheimer’s disease profile.”

Dr. Iliff, associate director for research, VA Northwest Mental Illness Research, Education, and Clinical Center at VA Puget Sound Health Care System, Seattle, suggested that the culprit may be impairment in the brain’s glymphatic system. “Recently described biological research supports [the concept of] clearance of waste out of the brain during sleep via the glymphatic system, with amyloid and tau being cleared from the brain interstitium during sleep.”

A recent hypothesis is that blast TBI impairs that process. “This is why we see less of those proteins in the CSF. They’re not being cleared, which might contribute downstream to the clumping up of protein in the brain,” he suggested.

The evidence base corroborating that hypothesis is in its infancy; however, new research conducted by Dr. Iliff and his colleagues sheds light on this potential mechanism.

In blast TBI, energy from the explosion and resulting overpressure wave are “transmitted through the brain, which causes tissues of different densities — such as gray and white matter — to accelerate at different rates,” according to Dr. Iliff. This results in the shearing and stretching of brain tissue, leading to a “diffuse pattern of tissue damage.”

It is known that blast TBI has clinical overlap and associations with posttraumatic stress disorder (PTSD), depression, and persistent neurobehavioral symptoms; that veterans with a history of TBI are more than twice as likely to die by suicide than veterans with no TBI history; and that TBI may increase the risk for Alzheimer’s disease and related dementing disorders, as well as CTE.

The missing link may be the glymphatic system — a “brain-wide network of perivascular pathways, along which CSF and interstitial fluid (ISF) exchange, supporting the clearance of interstitial solutes, including amyloid-beta.”

Dr. Iliff and his group previously found that glymphatic function is “markedly and chronically impaired” following impact TBI in mice and that this impairment is associated with the mislocalization of astroglial aquaporin 4 (AQP4), a water channel that lines perivascular spaces and plays a role in healthy glymphatic exchange.

In their new study, the researchers examined both the expression and the localization of AQP4 in the human postmortem frontal cortex and found “distinct laminar differences” in AQP4 expression following blast exposure. They observed similar changes as well as impairment of glymphatic function, which emerged 28 days following blast injury in a mouse model of repetitive blast mTBI.

And in a cohort of veterans with blast mTBI, blast exposure was found to be associated with an increased burden of frontal cortical MRI-visible perivascular spaces — a “putative neuroimaging marker” of glymphatic perivascular dysfunction.

The earlier Neurology study “showed impairment of biomarkers in the CSF, but the new study showed ‘why’ or ‘how’ these biomarkers are impaired, which is via impairment of the glymphatic clearance process,” Dr. Iliff explained.
 

Veterans Especially Vulnerable

Dr. Peskind, co-director of the VA Northwest Mental Illness Research, Education and Clinical Center, VA Puget Sound Health Care System, noted that while the veterans in the earlier study had at least one TBI, the average number was 20, and it was more common to have more than 50 mTBIs than to have a single one.

“These were highly exposed combat vets,” she said. “And that number doesn’t even account for subconcussive exposure to blasts, which now appear to cause detectable brain damage, even in the absence of a diagnosable TBI.”

The Maine shooter, Mr. Card, had not seen combat and was not assessed for TBI during a psychiatric hospitalization, according to The New York Times.

Dr. Peskind added that this type of blast damage is likely specific to individuals in the military. “It isn’t the sound that causes the damage,” she explained. “It’s the blast wave, the pressure wave, and there aren’t a lot of other occupations that have those types of occupational exposures.”

Dr. Snyder added that the majority of blast TBIs have been studied in military personnel, and she is not aware of studies that have looked at blast injuries in other industries, such as demolition or mining, to see if they have the same type of biologic consequences.

Dr. Snyder hopes that the researchers will follow the participants in the Neurology study and continue looking at specific markers related to Alzheimer’s disease brain changes. What the research so far shows “is that, at an earlier age, we’re starting to see those markers changing, suggesting that the underlying biology in people with mild blast TBI is similar to the underlying biology in Alzheimer’s disease as well.”

Michael Alosco, PhD, associate professor and vice chair of research, department of neurology, Boston University Chobanian & Avedisian School of Medicine, called the issue of blast exposure and TBI “a very complex and nuanced topic,” especially because TBI is “considered a risk factor of Alzheimer’s disease” and “different types of TBIs could trigger distinct pathophysiologic processes; however, the long-term impact of repetitive blast TBIs on neurodegenerative disease changes remains unknown.”

He coauthored an editorial on the earlier Neurology study that noted its limitations, such as a small sample size and lack of consideration of lifestyle and health factors but acknowledged that the “findings provide preliminary evidence that repetitive blast exposures might influence beta-amyloid accumulation.”
 

Clinical Implications

For Dr. Peskind, the “inflection point” was seeing lower CSF Abeta42, about 20 years earlier than ages 60 and 70, which is more typical in cognitively normal community volunteers.

But she described herself as “loath to say that veterans or service members have a 20-year acceleration of risk of Alzheimer’s disease,” adding, “I don’t want to scare the heck out of our service members of veterans.” Although “this is what we fear, we’re not ready to say it for sure yet because we need to do more work. Nevertheless, it does increase the index of suspicion.”

The clinical take-home messages are not unique to service members or veterans or people with a history of head injuries or a genetic predisposition to Alzheimer’s disease, she emphasized. “If anyone of any age or occupation comes in with cognitive issues, such as [impaired] memory or executive function, they deserve a workup for dementing disorders.” Frontotemporal dementia, for example, can present earlier than Alzheimer’s disease typically does.

Common comorbidities with TBI are PTSD and obstructive sleep apnea (OSA), which can also cause cognitive issues and are also risk factors for dementia.

Dr. Iliff agreed. “If you see a veteran with a history of PTSD, a history of blast TBI, and a history of OSA or some combination of those three, I recommend having a higher index of suspicion [for potential dementia] than for an average person without any of these, even at a younger age than one would ordinarily expect.”

Of all of these factors, the only truly directly modifiable one is sleep disruption, including that caused by OSA or sleep disorders related to PTSD, he added. “Epidemiologic data suggest a connection particularly between midlife sleep disruption and the risk of dementia and Alzheimer’s disease, and so it’s worth thinking about sleep as a modifiable risk factor even as early as the 40s and 50s, whether the patient is or isn’t a veteran.”

Dr. Peskind recommended asking patients, “Do they snore? Do they thrash about during sleep? Do they have trauma nightmares? This will inform the type of intervention required.”

Dr. Alosco added that there is no known “safe” threshold of exposure to blasts, and that thresholds are “unclear, particularly at the individual level.” In American football, there is a dose-response relationship between years of play and risk for later-life neurological disorder. “The best way to mitigate risk is to limit cumulative exposure,” he said.

In October 2023, Robert Card — a grenade instructor in the Army Reserve — shot and killed 18 people in Maine, before turning the gun on himself. As reported by The New York Times, his family said that he had become increasingly erratic and violent during the months before the rampage.

A postmortem conducted by the Chronic Traumatic Encephalopathy (CTE) Center at Boston University found “significant evidence of traumatic brain injuries” [TBIs] and “significant degeneration, axonal and myelin loss, inflammation, and small blood vessel injury” in the white matter, the center’s director, Ann McKee, MD, said in a press release. “These findings align with our previous studies on the effects of blast injury in humans and experimental models.”

Members of the military, such as Mr. Card, are exposed to blasts from repeated firing of heavy weapons not only during combat but also during training.

New data suggest that repeated blast exposure may impair the brain’s waste clearance system, leading to biomarker changes indicative of preclinical Alzheimer’s disease 20 years earlier than typical. A higher index of suspicion for dementia or Alzheimer’s disease may be warranted in patients with a history of blast exposure or subconcussive brain injury who present with cognitive issues, according to experts interviewed.

In 2022, the US Department of Defense (DOD) launched its Warfighter Brain Health Initiative with the aim of “optimizing service member brain health and countering traumatic brain injuries.”

In April 2024, the Blast Overpressure Safety Act was introduced in the Senate to require the DOD to enact better blast screening, tracking, prevention, and treatment. The DOD initiated 26 blast overpressure studies.

Heather Snyder, PhD, Alzheimer’s Association vice president of Medical and Scientific Relations, said that an important component of that research involves “the need to study the difference between TBI-caused dementia and dementia caused independently” and “the need to study biomarkers to better understand the long-term consequences of TBI.”
 

What Is the Underlying Biology?

Dr. Snyder was the lead author of a white paper produced by the Alzheimer’s Association in 2018 on military-related risk factors for Alzheimer’s disease and related dementias. “There is a lot of work trying to understand the effect of pure blast waves on the brain, as opposed to the actual impact of the injury,” she said.

The white paper speculated that blast exposure may be analogous to subconcussive brain injury in athletes where there are no obvious immediate clinical symptoms or neurological dysfunction but which can cause cumulative injury and functional impairment over time.

“We are also trying to understand the underlying biology around brain changes, such as accumulation of tau and amyloid and other specific markers related to brain changes in Alzheimer’s disease,” said Dr. Snyder, chair of the Peer Reviewed Alzheimer’s Research Program Programmatic Panel for Alzheimer’s Disease/Alzheimer’s Disease and Related Dementias and TBI.
 

Common Biomarker Signatures

A recent study in Neurology comparing 51 veterans with mild TBI (mTBI) with 85 veterans and civilians with no lifetime history of TBI is among the first to explore these biomarker changes in human beings.

“Our findings suggest that chronic neuropathologic processes associated with blast mTBI share properties in common with pathogenic processes that are precursors to Alzheimer’s disease onset,” said coauthor Elaine R. Peskind, MD, professor of psychiatry and behavioral sciences, University of Washington, Seattle.

The largely male participants were a mean age of 34 years and underwent standardized clinical and neuropsychological testing as well as lumbar puncture to collect cerebrospinal fluid (CSF). The mTBI group had experienced at least one war zone blast or combined blast/impact that met criteria for mTBI, but 91% had more than one blast mTBI, and the study took place over 13 years.

The researchers found that the mTBI group “had biomarker signatures in common with the earliest stages of Alzheimer’s disease,” said Dr. Peskind.

For example, at age 50, they had lower mean levels of CSF amyloid beta 42 (Abeta42), the earliest marker of brain parenchymal Abeta deposition, compared with the control group (154 pg/mL and 1864 pg/mL lower, respectively).

High CSF phosphorylated tau181 (p-tau181) and total tau are established biomarkers for Alzheimer’s disease. However, levels of these biomarkers remained “relatively constant with age” in participants with mTBI but were higher in older ages for the non-TBI group.

The mTBI group also showed worse cognitive performance at older ages (P < .08). Poorer verbal memory and verbal fluency performance were associated with lower CSF Abeta42 in older participants (P ≤ .05).

In Alzheimer’s disease, a reduction in CSF Abeta42 may occur up to 20 years before the onset of clinical symptoms, according to Dr. Peskind. “But what we don’t know from this study is what this means, as total tau protein and p-tau181 in the CSF were also low, which isn’t entirely typical in the picture of preclinical Alzheimer’s disease,” she said. However, changes in total tau and p-tau181 lag behind changes in Abeta42.

Brain imaging combined with artificial intelligence has identified six distinct “biotypes” of depression and anxiety that may lead to more personalized and effective treatment.

This research has “immediate clinical implications,” study investigator Leanne Williams, PhD, director of the Stanford Medicine Center for Precision Mental Health and Wellness, told this news organization.

“At Stanford, we have started translating the imaging technology into use in a new precision mental health clinic. The technology is being actively developed for wider use in clinical settings, and we hope to make it accessible to more clinicians and patients,” Dr. Williams said.

The study was published online in Nature Medicine.

 

No More Trial and Error?

Depression is a highly heterogeneous disease, with individual patients having different symptoms and treatment responses. About 30% of patients with major depression are resistant to treatment, and about half of patients with generalized anxiety disorder do not respond to first-line treatment.

“The dominant ‘one-size-fits-all’ diagnostic approach in psychiatry leads to cycling through treatment options by trial and error, which is lengthy, expensive, and frustrating, with 30%-40% of patients not achieving remission after trying one treatment,” the authors noted.

“The goal of our work is figuring out how we can get it right the first time,” Dr. Williams said in a news release, and that requires a better understanding of the neurobiology of depression.

To that end, 801 adults diagnosed with depression and anxiety underwent functional MRI to measure brain activity at rest and when engaged in tasks designed to test cognitive and emotional functioning.

Researchers probed six brain circuits previously associated with depression: the default mode circuit, salience circuit, attention circuit, negative affect circuit, positive affect circuit, and the cognitive control circuit.

Using a machine learning technique known as cluster analysis to group the patients’ brain images, they identified six clinically distinct biotypes of depression and anxiety defined by specific profiles of dysfunction within both task-free and task-evoked brain circuits.

“Importantly for clinical translation, these biotypes predict response to different pharmacological and behavioral interventions,” investigators wrote.

For example, patients with a biotype characterized by overactivity in cognitive regions of the brain experienced the best response to the antidepressant venlafaxine, compared with patients with other biotypes.

Patients with a different biotype, characterized by higher at-rest levels of activity in three regions associated with depression and problem-solving, responded better to behavioral therapy.

In addition, those with a third biotype, who had lower levels of activity at rest in the brain circuit that controls attention, were less apt to see improvement of their symptoms with behavioral therapy than those with other biotypes. The various biotypes also correlated with differences in symptoms and task performance.

For example, individuals with overactive cognitive regions of the brain had higher levels of anhedonia than those with other biotypes, and they also performed worse on tasks measuring executive function. Those with the biotype that responded best to behavioral therapy also made errors on executive function tasks but performed well on cognitive tasks.
 

A Work in Progress

The findings provide a deeper understanding of the neurobiological underpinnings of depression and anxiety and could lead to improved diagnostic accuracy and more tailored treatment approaches, the researchers noted.

Naming the biotypes is a work in progress, Dr. Williams said.

“We have thought a lot about the naming. In the Nature Medicine paper, we use a technical convention to name the biotypes based on which brain circuit problems define each of them,” she explained.

“For example, the first biotype is called DC+SC+AC+ because it is defined by connectivity increases [C+] on three resting circuits — default mode [D], salience [S], and frontoparietal attention [A]. We are working with collaborators to generate biotype names that could be convergent across findings and labs. In the near future, we anticipate generating more descriptive medical names that clinicians could refer to alongside the technical names,” Dr. Williams said.

Commenting on the research for this news organization, James Murrough, MD, PhD, director of the Depression and Anxiety Center for Research and Treatment at the Icahn School of Medicine at Mount Sinai, New York, called it “super exciting.”

“The work from this research group is an excellent example of where precision psychiatry research is right now, particularly with regard to the use of brain imaging to personalize treatment, and this paper gives us a glimpse of where we could be in the not-too-distant future,” Dr. Murrough said.

However, he cautioned that at this point, “we’re far from realizing the dream of precision psychiatry. We just don’t have robust evidence that brain imaging markers can really guide clinical decision-making currently.”

Funding for the study was provided by the National Institutes of Health and by Brain Resource Ltd. Dr. Williams declared US patent applications numbered 10/034,645 and 15/820,338: “Systems and methods for detecting complex networks in MRI data.” Dr. Murrough had no relevant disclosures.

For example, patients with a biotype characterized by overactivity in cognitive regions of the brain experienced the best response to the antidepressant venlafaxine, compared with patients with other biotypes.

Patients with a different biotype, characterized by higher at-rest levels of activity in three regions associated with depression and problem-solving, responded better to behavioral therapy.

In addition, those with a third biotype, who had lower levels of activity at rest in the brain circuit that controls attention, were less apt to see improvement of their symptoms with behavioral therapy than those with other biotypes. The various biotypes also correlated with differences in symptoms and task performance.

For example, individuals with overactive cognitive regions of the brain had higher levels of anhedonia than those with other biotypes, and they also performed worse on tasks measuring executive function. Those with the biotype that responded best to behavioral therapy also made errors on executive function tasks but performed well on cognitive tasks.
 

A Work in Progress

The findings provide a deeper understanding of the neurobiological underpinnings of depression and anxiety and could lead to improved diagnostic accuracy and more tailored treatment approaches, the researchers noted.

Naming the biotypes is a work in progress, Dr. Williams said.

“We have thought a lot about the naming. In the Nature Medicine paper, we use a technical convention to name the biotypes based on which brain circuit problems define each of them,” she explained.

“For example, the first biotype is called DC+SC+AC+ because it is defined by connectivity increases [C+] on three resting circuits — default mode [D], salience [S], and frontoparietal attention [A]. We are working with collaborators to generate biotype names that could be convergent across findings and labs. In the near future, we anticipate generating more descriptive medical names that clinicians could refer to alongside the technical names,” Dr. Williams said.

Commenting on the research for this news organization, James Murrough, MD, PhD, director of the Depression and Anxiety Center for Research and Treatment at the Icahn School of Medicine at Mount Sinai, New York, called it “super exciting.”

“The work from this research group is an excellent example of where precision psychiatry research is right now, particularly with regard to the use of brain imaging to personalize treatment, and this paper gives us a glimpse of where we could be in the not-too-distant future,” Dr. Murrough said.

However, he cautioned that at this point, “we’re far from realizing the dream of precision psychiatry. We just don’t have robust evidence that brain imaging markers can really guide clinical decision-making currently.”

Funding for the study was provided by the National Institutes of Health and by Brain Resource Ltd. Dr. Williams declared US patent applications numbered 10/034,645 and 15/820,338: “Systems and methods for detecting complex networks in MRI data.” Dr. Murrough had no relevant disclosures.

While Medicare Advantage (MA) plans are marketed as providing more generous benefits than traditional Medicare (TM), differences in the financial burden between beneficiaries switching to MA and staying with TM, are minimal, a longitudinal cohort analysis found.

In fact, according to a study by Sungchul Park, PhD, a health economist at Korea University in Seoul, and colleagues, the estimated annual out-of-pocket spending when switching to MA was $168 higher than staying in TM. That amounted to a 10.5% relative increase based on baseline out-of-pocket spending of $1597 annually among switchers, ranging widely, however, from a $133 decrease to a $469 increase. And for some, MA enrollment was associated with a higher likelihood of catastrophic financial burden.

“Our findings contrast with the notion that MA’s apparently more generous health insurance benefits lead to financial savings for enrollees,” Dr. Park and associates wrote in Annals of Internal Medicine.
 

The study

The analysis looked at costs for 7054 TM stayers and 1544 TM-to-MA switchers from the 2014-2020 Medical Expenditure Panel Survey, focusing on a cohort in which 18% of TM-covered individuals in year 1 switched to MA in year 2.

Comparative financial outcome measures included individual healthcare costs (out-of-pocket spending/cost sharing), financial burden (high/catastrophic), and subjective financial hardship (difficulty paying medical bills).

Although the overall out-of-pocket differences for MA were minimal and amounted to less than 1% of total healthcare expenses, MA was associated with a greater financial burden in vulnerable, especially in low-income populations. For every 100 beneficiaries with family incomes below 200% of the federal poverty level, one to six more switchers faced a catastrophic financial burden, with their out-of-pocket costs consuming more than 40% of household income in the year after switching.

The gap between the perception of lower costs and reality may be caused by a substantially heavier cost-sharing burden for certain services in MA plans, Dr. Park and associates pointed out. While MA enrollees generally paid less in some studies than the Part A hospital deductible for TM for inpatient stays of 3 days, they were more likely to face higher cost sharing for stays exceeding 7 days

Furthermore, whereas TM covers home health services without cost sharing, some MA plans have copayments. In addition, out-of-network health services can cost more. MA enrollees paid an average of $9 more for mental health services than for other in-network services and often encountered limited access to in-network providers. According to a 2021 study, only 18.2% of mental health professionals, 34.4% of cardiologists, 50.0% of psychiatrists, and 57.9% of primary care providers were included in MA networks,

An accompanying editorial noted that private MA plans will reap $83 billion in overpayments from U.S. taxpayers this year, according to Congress’s Medicare Payment Advisory Commission.

And as the data from Dr. Park and colleagues reveal, switchers don’t get much financial protection, according to primary care physician and healthcare researcher Steffi J. Woolhandler, MD, MPH, and internist David U. Himmelstein, MD, both of City University of New York at Hunter College in New York City.

“Medicare Advantage looks good when you’re healthy and don’t need much care. But when you need coverage, it often fails, leaving you with big bills and narrow choices for care,” Dr. Woolhandler said in an interview.

So how do these findings square with insurers’ hard-sell claims and enrollees’ perceptions that MA cuts out-of-pocket costs? “The likeliest explanation is that MA insurers have structured their benefits to advantage low-cost (that is, profitable) enrollees and disadvantage those requiring expensive care,” the editorial commentators wrote. For beneficiaries on inexpensive medications, MA plans would be a financial win. “But for patients requiring expensive chemotherapies, the 20% coinsurance that most MA plans charge could be financially ruinous.”

Commenting on the study but not involved in it, David A. Lipschutz, JD, LLB, associate director of the Center for Medicare Advocacy in Washington, DC, called the study an important one that provides more evidence that significant overpayments to MA plans don’t translate to better financial protections for plan enrollees, particularly lower-income individuals. “While there has been some recent movement to hold plans more accountable for providing necessary care, much more impactful action by policymakers is required to mitigate the harms of the growing privatization of the Medicare program,” he said. “MA overpayments could be redistributed to traditional Medicare in order to enrich all Medicare beneficiaries instead of just insurance companies.”

This study was supported by the National Research Foundation of Korea. Dr. Park disclosed no competing interests. One study coauthor reported support from government and not-for-profit research-funding bodies. Editorialists Dr. Woolhandler and Dr. Himmelstein had no competing interests to declare. Dr. Lipschutz disclosed Medicare advocacy work.

Some 15%-20% of the world’s population are neurodivergent, with conditions such as autism, dyslexia, Tourette syndrome, attention-deficit/hyperactivity disorder (ADHD), and others. With different strengths and challenges around learning, engaging socially, or completing certain tasks, neurodivergent people can face barriers in the workforce.

Meanwhile, studies suggest that neurodivergent people may be overrepresented in STEM fields such as medicine. The medical field may self-select for traits associated with neurodivergent conditions, researchers say, including a hyperfocus on intense interests, pattern recognition, increased curiosity and empathy, and thinking quickly under pressure.

But neurodivergent physicians report difficult, even damaging, experiences in the healthcare field. They struggle with stigma, a culture of nondisclosure, and lack of accommodations, which can lead to burnout and poor mental health.

“The medical system and the mental health system are some of the spaces that are holding on tightly to some of the outdated understandings of things like autism and ADHD,” says Megan Anna Neff, PsyD, a psychologist with autism and ADHD based in Portland, Oregon.

Situations can get dire: A 2023 survey of more than 200 autistic doctors from several countries found that 77% had considered suicide and 24% had attempted it.

But here’s the crux of it: Many neurodivergent doctors believe their unique ways of thinking and outside-the-box creativity are skills and strengths that can benefit the field. And they say making medicine more inclusive — and better understanding how a neurodivergent physician’s brain works — would allow them to thrive.
 

Blending In and Breaking Down

The exact number of neurodivergent physicians in the workforce remains unknown. Existing studies are small and focus mainly on autism. But researchers believe the percentage could be higher than we think, because neurodiversity can be underidentified.

Although autism can sometimes be diagnosed as early as 18 months, it’s not uncommon to receive a diagnosis well into adulthood. “Like many late-identified autistic adults, I got my autism diagnosis in the context of autistic burnout,” says Melissa Houser, MD, a primary care physician who received a diagnosis in 2021. Dr. Houser, who uses the pronouns she/they, explains that her experience is common, “a consequence of chronically having your life’s demands exceed your capacity.”

Dr. Houser, who also has ADHD and dyslexia, among other neurodivergent conditions, says that before her diagnosis, she worked in a traditional practice setting. Eventually, she began to notice intense dysregulation and fatigue. “I began to have a lot more difficulties with communication and my motor planning and sequencing,” Dr. Houser says. “I was sleep-deprived, and my needs were not being met. I was in a situation where I had a complete lack of autonomy over my practice.”

Deep in burnout, Dr. Houser says she lost her ability to “mask,” a term used to describe how some neurodivergent people work to “blend in” with societal expectations. This led to further communication breakdowns with her supervisor. Finally, Dr. Houser saw a psychiatrist.

Shortly after her diagnosis, Dr. Houser quit her job and founded All Brains Belong, a nonprofit that provides neurodiversity-affirming medical care, education, and advocacy. Research has found that people with autism are at increased risk for physical health conditions, including immune conditions, gastrointestinal disorders, metabolic conditions, and increased mortality in hospital settings. Understanding these connections can “mean the difference between life and death” for neurodivergent patients, Dr. Houser says.

Yet, in a 2015 study that assessed providers’ ability to recognize autism, a high proportion were not aware that they had patients with autism spectrum disorder, and most reported lacking both the skills and the tools to care for them.
 

Different as a Doctor and a Patient

Bernadette Grosjean, MD, a retired associate professor of psychiatry at David Geffen School of Medicine at UCLA and a distinguished Fellow of the American Psychiatric Association, also found insight into lifelong experiences as both a doctor and a patient with her autism diagnosis, which came when she was 61.

“Looking back, I was a smart kid but kind of clumsy and different in other ways,” Dr. Grosjean says. According to a 2021 survey by Cambridge University, autistic individuals are significantly more likely to identify as LGBTQ+, and Dr. Grosjean, who is gay, says that not being fully accepted by family or friends played a role in her struggles with mental health issues.

Throughout her mental health treatment, Dr. Grosjean felt as though her providers “were expecting from me things that I didn’t know how to do or fix. I didn’t know how to be a ‘good’ patient,” she recalls.

As a psychiatrist, Dr. Grosjean started to notice that many of the women she treated for borderline personality disorder, which is categorized by unstable relationships and emotions, were autistic. “I then started asking lots of questions about myself — the fact that I’ve always been very sensitive or that I’ve been accused of being both hypersensitive and not having emotions, and I understood a lot.”

When Dr. Grosjean came across Autistic Doctors International, a group of over 800 autistic doctors worldwide, she says, “I found my tribe.” She now serves as the US lead for psychiatry for the group, which is focused on support, advocacy, research, and education around neurodiversity.

Psychiatric comorbidities can accompany neurodivergent conditions. But a growing body of research, including a 2022 study published in the European Archives of Psychiatry and Clinical Neuroscience, indicates that autism and ADHD are frequently misdiagnosed as depression or anxiety.

Dr. Neff was unaware of her conditions until one of her children was diagnosed with autism in 2021. She started to research it. “As I was learning about autism and girls, I was like, ‘Oh, my gosh, this is me,’ ” Dr. Neff recalls. Within a few weeks, she had her own diagnosis.

In hindsight, Dr. Neff has more clarity regarding her struggles in the traditional medical space. She had found it difficult to fit patients into short appointment windows and keep their notes concise. Although she loved hospital work, the environment had been overwhelming and led to burnout.
 

‘A Deficit-Based Lens’

Dr. Houser believes that too often, autism is viewed through a “deficit-based lens.” Stressors like sensory overload, changes in routine, or unexpected events can exacerbate behavioral challenges for neurodivergent people in the workplace. The DSM-5 criteria for autism, she points out, are largely based on autistic “stress behaviors.”

The result, Dr. Houser says, is that neurodivergent doctors are judged by their response to stressors that put them at a disadvantage rather than their capabilities under more positive circumstances. “The more dysregulated someone is,” she says, “the more likely they are to manifest those observable behaviors.”

Dr. Neff notes that medicine is a very “sensory overwhelming work environment.” Working in ob.gyn. and primary care clinics, she remembers often coming home with a headache and a low-grade fever. “I had no idea why, but I now realize it’s because I was so sensory sick.”

Fearing for her job, Dr. Neff intentionally waited until she was in private practice to disclose her neurodiversity. “I don’t think it would have been received well if I was in a hospital system,” she says. “There’s a lot of invalidation that can come when someone chooses to self-disclose, and their colleagues don’t have a framework in mind to understand.” In one instance, after revealing her diagnosis, she remembers a well-known researcher telling her she wasn’t autistic.
Dr. Grosjean has also had former colleagues invalidate her diagnosis, something she says “keeps people quiet.”
 

Understanding the Neurodivergent Brain

The general lack of education on how neurodivergent brains work, physicians with these conditions say, means they are not often recognized for how they can function with certain accommodations and how they could contribute in unique ways if their workplace challenges were reduced.

“What we know about autistic brains is that we are systems-thinking pattern matchers,” says Dr. Houser, who formed an interdisciplinary task force to explore medical conditions that are more common in autistic people. Through that comprehensive approach, she has worked to find best practices to treat the constellation of conditions that can arise among these patients. “My autistic brain allowed me to do that,” Dr. Houser says.

Catriona McVey, a medical student in the United Kingdom and creator of the blog Attention Deficit Doctor, points out that “ADHD brains are interest-driven; they can be very focused when you’re doing something enjoyable or new due to increased dopaminergic stimulation.” Ms. McVey speaks from personal experience. “I’ve hyperfocused before on an essay that interested me for over 10 hours,” she recalls, “so I imagine if I was interested in surgery, I could easily hyperfocus on a long operation.” 

Empathy is another key part of medical practice. Contrary to stereotypes of neurodivergent people lacking empathy, current research suggests this isn’t true. A concept known as the “double empathy problem,” a term coined by British researcher Damian Milton in 2012, challenges the misconception that autistic people do not have empathy, explains Dr. Grosjean.

Mr. Milton theorized that there are two types of empathy: emotional, when you feel someone else’s pain, and cognitive, which involves critical thinking to understand someone’s emotions or thoughts. “Autistic people have, in general, a lot of emotional empathy,” Dr. Grosjean says, “but the cognitive empathy they don’t have as well.”

Dr. Neff has experienced this in her practice. “I will often feel what my clients are feeling as they’re feeling it,” she says, adding that she has always had an innate ability to analyze and connect with clients. She’s good at observing the interplay of health conditions, incorporating biology, psychology, and social conceptualizations of issues, with nuance. She feels that recognizing behavioral patterns or psychological triggers in her patients helps her see them holistically and provide better care. “That was a skill even before I realized I was autistic, but I always thought it was just intuitive to everyone,” she says. 
 

Support Can Lead to Success

The Americans with Disabilities Act requires employers to provide reasonable accommodations to neurodivergent employees. However, getting those accommodations involves disclosure, which many physicians have reasons to avoid.

It also means more work. Requesting and putting adjustments in place can take a lot of time and energy to organize. Ms. McVey says they can be “long-winded, multistep tasks” that are not very compatible with ADHD. “Some doctors report that service pressures and funding are used as excuses to refuse adjustments,” she adds. 

Ms. McVey lists several workplace accommodations that could be helpful, including flexible working hours, a quiet space to complete paperwork, dictation software, and extra time for medical students to complete written exams.

Neurodivergent physicians have also called for increased diversity of senior leadership and utilizing “cognitive apprenticeship models,” where employees explain their thought processes and receive timely feedback.

But far too often, there is little intervention until a doctor reaches a crisis point. “I look forward to the day when we don’t have to wait until people are profoundly depleted to discover how their brains work,” says Dr. Houser.

Beyond logistical and structural changes in the medical field, Dr. Grosjean speaks of the simple need to listen to colleagues with an open mind and believe them when they express their feelings and experiences. “Everyone has a role to play in challenging stigma, misconceptions, and stereotypes,” Ms. McVey agrees. Ask yourself the old question, she suggests: “If not me, then who? If not now, then when?”

Dr. Houser believes that too often, autism is viewed through a “deficit-based lens.” Stressors like sensory overload, changes in routine, or unexpected events can exacerbate behavioral challenges for neurodivergent people in the workplace. The DSM-5 criteria for autism, she points out, are largely based on autistic “stress behaviors.”

The result, Dr. Houser says, is that neurodivergent doctors are judged by their response to stressors that put them at a disadvantage rather than their capabilities under more positive circumstances. “The more dysregulated someone is,” she says, “the more likely they are to manifest those observable behaviors.”

Dr. Neff notes that medicine is a very “sensory overwhelming work environment.” Working in ob.gyn. and primary care clinics, she remembers often coming home with a headache and a low-grade fever. “I had no idea why, but I now realize it’s because I was so sensory sick.”

Fearing for her job, Dr. Neff intentionally waited until she was in private practice to disclose her neurodiversity. “I don’t think it would have been received well if I was in a hospital system,” she says. “There’s a lot of invalidation that can come when someone chooses to self-disclose, and their colleagues don’t have a framework in mind to understand.” In one instance, after revealing her diagnosis, she remembers a well-known researcher telling her she wasn’t autistic.
Dr. Grosjean has also had former colleagues invalidate her diagnosis, something she says “keeps people quiet.”
 

Understanding the Neurodivergent Brain

The general lack of education on how neurodivergent brains work, physicians with these conditions say, means they are not often recognized for how they can function with certain accommodations and how they could contribute in unique ways if their workplace challenges were reduced.

“What we know about autistic brains is that we are systems-thinking pattern matchers,” says Dr. Houser, who formed an interdisciplinary task force to explore medical conditions that are more common in autistic people. Through that comprehensive approach, she has worked to find best practices to treat the constellation of conditions that can arise among these patients. “My autistic brain allowed me to do that,” Dr. Houser says.

Catriona McVey, a medical student in the United Kingdom and creator of the blog Attention Deficit Doctor, points out that “ADHD brains are interest-driven; they can be very focused when you’re doing something enjoyable or new due to increased dopaminergic stimulation.” Ms. McVey speaks from personal experience. “I’ve hyperfocused before on an essay that interested me for over 10 hours,” she recalls, “so I imagine if I was interested in surgery, I could easily hyperfocus on a long operation.” 

Empathy is another key part of medical practice. Contrary to stereotypes of neurodivergent people lacking empathy, current research suggests this isn’t true. A concept known as the “double empathy problem,” a term coined by British researcher Damian Milton in 2012, challenges the misconception that autistic people do not have empathy, explains Dr. Grosjean.

Mr. Milton theorized that there are two types of empathy: emotional, when you feel someone else’s pain, and cognitive, which involves critical thinking to understand someone’s emotions or thoughts. “Autistic people have, in general, a lot of emotional empathy,” Dr. Grosjean says, “but the cognitive empathy they don’t have as well.”

Dr. Neff has experienced this in her practice. “I will often feel what my clients are feeling as they’re feeling it,” she says, adding that she has always had an innate ability to analyze and connect with clients. She’s good at observing the interplay of health conditions, incorporating biology, psychology, and social conceptualizations of issues, with nuance. She feels that recognizing behavioral patterns or psychological triggers in her patients helps her see them holistically and provide better care. “That was a skill even before I realized I was autistic, but I always thought it was just intuitive to everyone,” she says. 
 

Support Can Lead to Success

The Americans with Disabilities Act requires employers to provide reasonable accommodations to neurodivergent employees. However, getting those accommodations involves disclosure, which many physicians have reasons to avoid.

It also means more work. Requesting and putting adjustments in place can take a lot of time and energy to organize. Ms. McVey says they can be “long-winded, multistep tasks” that are not very compatible with ADHD. “Some doctors report that service pressures and funding are used as excuses to refuse adjustments,” she adds. 

Ms. McVey lists several workplace accommodations that could be helpful, including flexible working hours, a quiet space to complete paperwork, dictation software, and extra time for medical students to complete written exams.

Neurodivergent physicians have also called for increased diversity of senior leadership and utilizing “cognitive apprenticeship models,” where employees explain their thought processes and receive timely feedback.

But far too often, there is little intervention until a doctor reaches a crisis point. “I look forward to the day when we don’t have to wait until people are profoundly depleted to discover how their brains work,” says Dr. Houser.

Beyond logistical and structural changes in the medical field, Dr. Grosjean speaks of the simple need to listen to colleagues with an open mind and believe them when they express their feelings and experiences. “Everyone has a role to play in challenging stigma, misconceptions, and stereotypes,” Ms. McVey agrees. Ask yourself the old question, she suggests: “If not me, then who? If not now, then when?”

Some 15%-20% of the world’s population are neurodivergent, with conditions such as autism, dyslexia, Tourette syndrome, attention-deficit/hyperactivity disorder (ADHD), and others. With different strengths and challenges around learning, engaging socially, or completing certain tasks, neurodivergent people can face barriers in the workforce.

Meanwhile, studies suggest that neurodivergent people may be overrepresented in STEM fields such as medicine. The medical field may self-select for traits associated with neurodivergent conditions, researchers say, including a hyperfocus on intense interests, pattern recognition, increased curiosity and empathy, and thinking quickly under pressure.

But neurodivergent physicians report difficult, even damaging, experiences in the healthcare field. They struggle with stigma, a culture of nondisclosure, and lack of accommodations, which can lead to burnout and poor mental health.

“The medical system and the mental health system are some of the spaces that are holding on tightly to some of the outdated understandings of things like autism and ADHD,” says Megan Anna Neff, PsyD, a psychologist with autism and ADHD based in Portland, Oregon.

Situations can get dire: A 2023 survey of more than 200 autistic doctors from several countries found that 77% had considered suicide and 24% had attempted it.

But here’s the crux of it: Many neurodivergent doctors believe their unique ways of thinking and outside-the-box creativity are skills and strengths that can benefit the field. And they say making medicine more inclusive — and better understanding how a neurodivergent physician’s brain works — would allow them to thrive.
 

Blending In and Breaking Down

The exact number of neurodivergent physicians in the workforce remains unknown. Existing studies are small and focus mainly on autism. But researchers believe the percentage could be higher than we think, because neurodiversity can be underidentified.

Although autism can sometimes be diagnosed as early as 18 months, it’s not uncommon to receive a diagnosis well into adulthood. “Like many late-identified autistic adults, I got my autism diagnosis in the context of autistic burnout,” says Melissa Houser, MD, a primary care physician who received a diagnosis in 2021. Dr. Houser, who uses the pronouns she/they, explains that her experience is common, “a consequence of chronically having your life’s demands exceed your capacity.”

Dr. Houser, who also has ADHD and dyslexia, among other neurodivergent conditions, says that before her diagnosis, she worked in a traditional practice setting. Eventually, she began to notice intense dysregulation and fatigue. “I began to have a lot more difficulties with communication and my motor planning and sequencing,” Dr. Houser says. “I was sleep-deprived, and my needs were not being met. I was in a situation where I had a complete lack of autonomy over my practice.”

Deep in burnout, Dr. Houser says she lost her ability to “mask,” a term used to describe how some neurodivergent people work to “blend in” with societal expectations. This led to further communication breakdowns with her supervisor. Finally, Dr. Houser saw a psychiatrist.

Shortly after her diagnosis, Dr. Houser quit her job and founded All Brains Belong, a nonprofit that provides neurodiversity-affirming medical care, education, and advocacy. Research has found that people with autism are at increased risk for physical health conditions, including immune conditions, gastrointestinal disorders, metabolic conditions, and increased mortality in hospital settings. Understanding these connections can “mean the difference between life and death” for neurodivergent patients, Dr. Houser says.

Yet, in a 2015 study that assessed providers’ ability to recognize autism, a high proportion were not aware that they had patients with autism spectrum disorder, and most reported lacking both the skills and the tools to care for them.
 

Different as a Doctor and a Patient

Bernadette Grosjean, MD, a retired associate professor of psychiatry at David Geffen School of Medicine at UCLA and a distinguished Fellow of the American Psychiatric Association, also found insight into lifelong experiences as both a doctor and a patient with her autism diagnosis, which came when she was 61.

“Looking back, I was a smart kid but kind of clumsy and different in other ways,” Dr. Grosjean says. According to a 2021 survey by Cambridge University, autistic individuals are significantly more likely to identify as LGBTQ+, and Dr. Grosjean, who is gay, says that not being fully accepted by family or friends played a role in her struggles with mental health issues.

Throughout her mental health treatment, Dr. Grosjean felt as though her providers “were expecting from me things that I didn’t know how to do or fix. I didn’t know how to be a ‘good’ patient,” she recalls.

As a psychiatrist, Dr. Grosjean started to notice that many of the women she treated for borderline personality disorder, which is categorized by unstable relationships and emotions, were autistic. “I then started asking lots of questions about myself — the fact that I’ve always been very sensitive or that I’ve been accused of being both hypersensitive and not having emotions, and I understood a lot.”

When Dr. Grosjean came across Autistic Doctors International, a group of over 800 autistic doctors worldwide, she says, “I found my tribe.” She now serves as the US lead for psychiatry for the group, which is focused on support, advocacy, research, and education around neurodiversity.

Psychiatric comorbidities can accompany neurodivergent conditions. But a growing body of research, including a 2022 study published in the European Archives of Psychiatry and Clinical Neuroscience, indicates that autism and ADHD are frequently misdiagnosed as depression or anxiety.

Dr. Neff was unaware of her conditions until one of her children was diagnosed with autism in 2021. She started to research it. “As I was learning about autism and girls, I was like, ‘Oh, my gosh, this is me,’ ” Dr. Neff recalls. Within a few weeks, she had her own diagnosis.

In hindsight, Dr. Neff has more clarity regarding her struggles in the traditional medical space. She had found it difficult to fit patients into short appointment windows and keep their notes concise. Although she loved hospital work, the environment had been overwhelming and led to burnout.

TOPLINE:

Poor vision and contrast sensitivity at baseline increase the likelihood of incident dementia in older adults; a decline in contrast sensitivity over time also correlates with the risk of developing dementia.

METHODOLOGY:

• Researchers conducted a longitudinal study to analyze the association of visual function with the risk for dementia in 2159 men and women (mean age, 77.9 years; 54% women) included from the National Health and Aging Trends Study between 2021 and 2022.
• All participants were free from dementia at baseline and underwent visual assessment while wearing their usual glasses or contact lenses.
• Distance and near visual acuity were measured as the log minimum angle of resolution (logMAR) units where higher values indicated worse visual acuity; contrast sensitivity was measured as the log contrast sensitivity (logCS) units where lower values represented worse outcomes.
• Dementia status was determined by a medical diagnosis, a dementia score of 2 or more, or poor performance on cognitive testing.

TAKEAWAY:

• Over the 1-year follow-up period, 192 adults (6.6%) developed dementia.
• Worsening of distant and near vision by 0.1 logMAR increased the risk for dementia by 8% (P = .01) and 7% (P = .02), respectively.
• Each 0.1 logCS decline in baseline contrast sensitivity increased the risk for dementia by 9% (P = .003).
• A yearly decline in contrast sensitivity by 0.1 logCS increased the likelihood of dementia by 14% (P = .007).
• Changes in distant and near vision over time did not show a significant association with risk for dementia (P = .58 and P = .79, respectively).

IN PRACTICE:

“Visual function, especially contrast sensitivity, might be a risk factor for developing dementia,” the authors wrote. “Early vision screening may help identify adults at higher risk of dementia, allowing for timely interventions.”

SOURCE:

The study was led by Louay Almidani, MD, MSc, of the Wilmer Eye Institute at the Johns Hopkins University School of Medicine, in Baltimore, and was published online in the American Journal of Ophthalmology.

LIMITATIONS:

The study had a limited follow-up period of 1 year and may not have captured the long-term association between visual impairment and the risk for dementia. Moreover, the researchers did not consider other visual function measures such as depth perception and visual field, which might have affected the results.

DISCLOSURES:

The study did not have any funding source. The authors declared no conflicts of interest.

CHICAGO —The use of kratom, an opioid-like supplement widely available over the counter at convenience stores, smoke shops, and online, is resulting in emerging cases of hyperpigmentation, most often on the face and hands.

“This is something we will see more and more,” Heather Woolery-Lloyd, MD, director of the Skin of Color Division at the University of Miami Department of Dermatology, said at the Pigmentary Disorders Exchange Symposium. The key marker of this hyperpigmentation, she said, is that “it’s strongly photoaccentuated,” affecting areas exposed to the sun — but it also tends to spare the knuckles on patients’ hands.
 

Used Like an Opioid, But It’s Not Regulated

Kratom is a plant common in southeast Asia and is used as an analgesic. It’s marketed as a “legal opioid” or “legal high” and is sold in 2- or 3-ounce containers of extract or sold as a powder, Dr. Woolery-Lloyd said. The leaves may be boiled into a tea, smoked, chewed, or put into capsules, according to a case report published in February in the Journal of Integrative Dermatology. It is used worldwide and is not regulated in the United States.

“Many of our patients think kratom is a safe, herbal supplement” but often don’t know it can have several side effects and can be addictive, Dr. Woolery-Lloyd said. Its popularity is increasing as reflected by the number of posts related to kratom on social media platforms.

In the February case report, Shaina Patel, BA, and Nathaniel Phelan, MD, from Kansas City University, Kansas City, Missouri, wrote that side effects of kratom include drowsiness, tachycardia, vomiting, respiratory depression, and cardiac arrest, in addition to confusion and hallucinations.

Kratom also has many different effects on the psyche, Dr. Woolery-Lloyd said at the meeting. At low doses, it blocks the reuptake of norepinephrine, serotonin, and dopamine, producing a motivational effect, and at high doses, it creates an analgesic, calming effect. And people who chronically consume high doses of kratom may be susceptible to hyperpigmentation.

Kratom-associated hyperpigmentation should be considered as a diagnosis when evaluating patients for other drug-associated pigmentary disorders, “especially if pigment is photodistributed,” she said. “If you see new-onset hyperpigmentation or onset over several months and it’s very photoaccentuated, definitely ask about use of kratom.”
 

Case Reports Show Patterns of Presentation

A 2022 report from Landon R. Powell, BS, with the department of biology, Whitworth University in Spokane, Washington, and coauthors, published in JAAD Case Reports, noted that kratom use in the United States has increased dramatically. “As measured by call reports to the United States National Poison Data System, in 2011, there were 11 reported kratom exposures, and in the first 7 months of 2018, there were 357 reported exposures,” they wrote.

An estimated 1.7 million Americans aged ≥ 12 years said they had used kratom in the previous year, according to the Substance Abuse and Mental Health Services Administration 2021 National Survey on Drug Use and Health.

In the case report, Mr. Powell and coauthors described a 54-year-old White male patient who had been using kratom for the previous four to five years to reduce opioid use. During this period, he consumed kratom powder mixed with orange juice three to four times a day. He presented with “diffuse hyperpigmented patches on his arms and face in a photodistributed manner, with notable sparing of the knuckles on both hands.”
 

Dark Gray-Blue Skin

In the more recent case report, Ms. Patel and Dr. Phelan described a 30-year-old White male patient who presented with dark gray-blue skin coloring on his cheeks, back of his neck, and the backs of his hands and forearms. He had no other medical conditions and did not take any medications or supplements that cause hyperpigmentation while using kratom.

The patient had been taking kratom for years in the wake of an opioid addiction following medications for a high school injury. He developed an opioid use disorder and tried to replace his pain medications with kratom.

“The patient stopped using kratom in May 2022, but the discoloration remains. It has not regressed in the following 16 months after discontinuing kratom use,” the authors wrote, noting that “whether or not the hyperpigmentation is able to regress is unknown.”

Dr. Woolery-Lloyd is a consultant for AbbVie, Incyte, Johnson & Johnson Consumer, LivDerm, and L’Oreal; a speaker for Eli Lilly, Incyte, L’Oreal, and Ortho Dermatologics; and a researcher/investigator for AbbVie, Allergan, Eirion Therapeutics, Galderma, Pfizer, Sanofi, and Vyne Therapeutics.
 

According to an information page on kratom on the Food and Drug Administration website, health care professionals and consumers can report adverse reactions associated with kratom to the FDA’s MedWatch program.

The key marker of this hyperpigmentation, she said, is that “it’s strongly photoaccentuated,” affecting areas exposed to the sun — but it also tends to spare the knuckles on patients’ hands.
 

Used Like an Opioid, But It’s Not Regulated

Kratom is a plant common in southeast Asia and is used as an analgesic. It’s marketed as a “legal opioid” or “legal high” and is sold in 2- or 3-ounce containers of extract or sold as a powder, Dr. Woolery-Lloyd said. The leaves may be boiled into a tea, smoked, chewed, or put into capsules, according to a case report published in February in the Journal of Integrative Dermatology. It is used worldwide and is not regulated in the United States.

“Many of our patients think kratom is a safe, herbal supplement” but often don’t know it can have several side effects and can be addictive, Dr. Woolery-Lloyd said. Its popularity is increasing as reflected by the number of posts related to kratom on social media platforms.

In the February case report, Shaina Patel, BA, and Nathaniel Phelan, MD, from Kansas City University, Kansas City, Missouri, wrote that side effects of kratom include drowsiness, tachycardia, vomiting, respiratory depression, and cardiac arrest, in addition to confusion and hallucinations.

Kratom also has many different effects on the psyche, Dr. Woolery-Lloyd said at the meeting. At low doses, it blocks the reuptake of norepinephrine, serotonin, and dopamine, producing a motivational effect, and at high doses, it creates an analgesic, calming effect. And people who chronically consume high doses of kratom may be susceptible to hyperpigmentation.

Kratom-associated hyperpigmentation should be considered as a diagnosis when evaluating patients for other drug-associated pigmentary disorders, “especially if pigment is photodistributed,” she said. “If you see new-onset hyperpigmentation or onset over several months and it’s very photoaccentuated, definitely ask about use of kratom.”
 

Case Reports Show Patterns of Presentation

A 2022 report from Landon R. Powell, BS, with the department of biology, Whitworth University in Spokane, Washington, and coauthors, published in JAAD Case Reports, noted that kratom use in the United States has increased dramatically. “As measured by call reports to the United States National Poison Data System, in 2011, there were 11 reported kratom exposures, and in the first 7 months of 2018, there were 357 reported exposures,” they wrote.

An estimated 1.7 million Americans aged ≥ 12 years said they had used kratom in the previous year, according to the Substance Abuse and Mental Health Services Administration 2021 National Survey on Drug Use and Health.

In the case report, Mr. Powell and coauthors described a 54-year-old White male patient who had been using kratom for the previous four to five years to reduce opioid use. During this period, he consumed kratom powder mixed with orange juice three to four times a day. He presented with “diffuse hyperpigmented patches on his arms and face in a photodistributed manner, with notable sparing of the knuckles on both hands.”
 

Dark Gray-Blue Skin

In the more recent case report, Ms. Patel and Dr. Phelan described a 30-year-old White male patient who presented with dark gray-blue skin coloring on his cheeks, back of his neck, and the backs of his hands and forearms. He had no other medical conditions and did not take any medications or supplements that cause hyperpigmentation while using kratom.

The patient had been taking kratom for years in the wake of an opioid addiction following medications for a high school injury. He developed an opioid use disorder and tried to replace his pain medications with kratom.

“The patient stopped using kratom in May 2022, but the discoloration remains. It has not regressed in the following 16 months after discontinuing kratom use,” the authors wrote, noting that “whether or not the hyperpigmentation is able to regress is unknown.”

According to an information page on kratom on the Food and Drug Administration website, health care professionals and consumers can report adverse reactions associated with kratom to the FDA’s MedWatch program.
