In a 2023 study published in the Annals of Emergency Medicine, European researchers fed the AI system ChatGPT information on 30 ER patients. Details included physician notes on the patients’ symptoms, physical exams, and lab results. ChatGPT made the correct diagnosis in 97% of patients compared to 87% for human doctors.

Should we stop? Because we could go on. In the last few years, these AI vs Physician studies have proliferated, and guess who’s winning?

65% of Doctors are Concerned

Now, the standard answer with anything AI-and-Medicine goes something like this: AI is coming, and it will be a transformative tool for physicians and improve patient care.

But the underlying unanswered question is: Physicians spend many years and a lot of money to become really good at what they do. How, exactly, should a doctor feel about a machine that can suddenly do the job better and faster?

The Medscape 2023 Physician and AI Report surveyed 1043 US physicians about their views on AI. In total, 65% are concerned about AI making diagnosis and treatment decisions, but 56% are enthusiastic about having it as an adjunct.

Cardiologists, anesthesiologists, and radiologists are most enthusiastic about AI, whereas family physicians and pediatricians are the least enthusiastic.

To get a more personal view of how physicians and other healthcare professionals are feeling about this transformative tech, I spoke with a variety of practicing doctors, a psychotherapist, and a third-year Harvard Medical School student.

‘Abysmally Poor Understanding’

Alfredo A. Sadun, MD, PhD, has been a neuro-ophthalmologist for nearly 50 years. A graduate of MIT and vice-chair of ophthalmology at UCLA, he’s long been fascinated by AI’s march into medicine. He’s watched it accomplish things that no ophthalmologist can do, such as identify gender, age, and risk for heart attack and stroke from retinal scans. But he doesn›t see the same level of interest and comprehension among the medical community.

“There’s still an abysmally poor understanding of AI among physicians in general,” he said. “It’s striking because these are intelligent, well-educated people. But we tend to draw conclusions based on what we’re familiar with, and most doctors’ experience with computers involves EHRs [electronic health records] and administrative garbage. It’s the reason they’re burning out.”

Easing the Burden

Anthony Philippakis, MD, PhD, left his cardiology practice in 2015 to become the chief data officer at the Broad Institute of MIT and Harvard. While there, he helped develop an AI-based method for identifying patients at risk for atrial fibrillation. Now, he’s a general partner at Google Ventures with the goal of bridging the gap between data sciences and medicine. His perspective on AI is unique, given that he’s seen the issue from both sides.

“I am not a bitter physician, but to be honest, when I was practicing, way too much of my time was spent staring at screens and not enough laying hands on patients,” he said. “Can you imagine what it would be like to speak to the EHR naturally and say, ‘Please order the following labs for this patient and notify me when the results come in.’ Boy, would that improve healthcare and physician satisfaction. Every physician I know is excited and optimistic about that. Almost everyone I’ve talked to feels like AI could take a lot of the stuff they don’t like doing off their plates.”

Indeed, the dividing line between physician support for AI and physician suspicion or skepticism of AI is just that. In our survey, more than three quarters of physicians said they would consider using AI for office administrative tasks, scheduling, EHRs, researching medical conditions, and even summarizing a patient’s record before a visit. But far fewer are supportive of it delivering diagnoses and treatments. This, despite an estimated 800,000 Americans dying or becoming permanently disabled each year because of diagnostic error.

Could AI Have Diagnosed This?

John D. Nuschke, MD, has been a primary care physician in Allentown, Pennsylvania, for 40 years. He’s a jovial general physician who insists his patients call him Jack. He’s recently started using an AI medical scribe called Freed. With the patient’s permission, it listens in on the visit and generates notes, saving Dr. Nuschke time and helping him focus on the person. He likes that type of assistance, but when it comes to AI replacing him, he’s skeptical.

“I had this patient I diagnosed with prostate cancer,” he explained. “He got treated and was fine for 5 years. Then, he started losing weight and feeling awful — got weak as a kitten. He went back to his urologist and oncologist who thought he had metastatic prostate cancer. He went through PET scans and blood work, but there was no sign his cancer had returned. So the specialists sent him back to me, and the second he walked in, I saw he was floridly hyperthyroid. I could tell across the room just by looking at him. Would AI have been able to make that diagnosis? Does AI do physical exams?”

Dr. Nuschke said he’s also had several instances where patients received their cancer diagnosis from the lab through an automated patient-portal system rather than from him. “That’s an AI of sorts, and I found it distressing,” he said.

Empathy From a Robot

All the doctors I spoke to were hopeful that by freeing them from the burden of administrative work, they would be able to return to the reason they got into this business in the first place — to spend more time with patients in need and support them with grace and compassion.

But suppose AI could do that too?

In a 2023 study conducted at the University of California San Diego and published in JAMA Internal Medicine, three licensed healthcare professionals compared the responses of ChatGPT and physicians to real-world health questions. The panel rated the AI’s answers nearly four times higher in quality and almost 10 times more empathetic than physicians’ replies.

A similar 2024 study in Nature found that Google’s large-language model AI matched or surpassed physician diagnostic accuracy in all six of the medical specialties considered. Plus, it outperformed doctors in 24 of 26 criteria for conversation quality, including politeness, explanation, honesty, and expressing care and commitment.

Nathaniel Chin, MD, is a gerontologist at the University of Wisconsin and advisory board member for the Alzheimer’s Foundation of America. Although he admits that studies like these “sadden me,” he’s also a realist. “There was hesitation among physicians at the beginning of the pandemic to virtual care because we missed the human connection,” he explained, “but we worked our way around that. We need to remember that what makes a chatbot strong is that it’s nothuman. It doesn’t burn out, it doesn’t get tired, it can look at data very quickly, and it doesn’t have to go home to a family and try to balance work with other aspects of life. A human being is very complex, whereas a chatbot has one single purpose.”

“Even if you don’t have AI in your space now or don’t like the idea of it, that doesn’t matter,” he added. “It’s coming. But it needs to be done right. If AI is implemented by clinicians for clinicians, it has great potential. But if it’s implemented by businesspeople for business reasons, perhaps not.”

‘The Ones Who Use the Tools the Best Will Be the Best’

One branch of medicine that stands to be dramatically affected by AI is mental health. Because bots are natural data-crunchers, they are becoming adept at analyzing the many subtle clues (phrasing in social media posts and text messages, smartwatch biometrics, therapy session videos…) that could indicate depression or other psychological disorders. In fact, its availability via smartphone apps could help democratize and destigmatize the practice.

“There is a day ahead — probably within 5 years — when a patient won’t be able to tell the difference between a real therapist and an AI therapist,” said Ken Mallon, MS, LMFT, a clinical psychotherapist and data scientist in San Jose, California. “That doesn’t worry me, though. It’s hard on therapists’ egos, but new technologies get developed. Things change. People who embrace these tools will benefit from them. The ones who use the tools the best will be the best.”

Time to Restructure Med School

Aditya Jain is in his third year at Harvard Medical School. At age 24, he’s heading into this brave new medical world with excitement and anxiety. Excitement because he sees AI revolutionizing healthcare on every level. Although the current generations of physicians and patients may grumble about its onset, he believes younger ones will feel comfortable with “DocGPT.” He’s excited that his generation of physicians will be the “translators and managers of this transition” and redefine “what it means to be a doctor.”

His anxiety, however, stems from the fact that AI has come on so fast that “it has not yet crossed the threshold of medical education,” he said. “Medical schools still largely prepare students to work as solo clinical decision makers. Most of my first 2 years were spent on pattern recognition and rote memorization, skills that AI can and will master.”

Indeed, Mr. Jain said AI was not a part of his first- or second-year curriculum. “I talk to students who are a year older than me, graduating, heading to residency, and they tell me they wish they had gotten a better grasp of how to use these technologies in medicine and in their practice. They were surprised to hear that people in my year hadn’t started using ChatGPT. We need to expend a lot more effort within the field, within academia, within practicing physicians, to figure out what our role will be in a world where AI is matching or even exceeding human intelligence. And then we need to restructure the medical education to better accomplish these goals.”

So Are You Ready for AI to Be a Better Doctor Than You?

“Yes, I am,” said Dr. Philippakis without hesitation. “When I was going through my medical training, I was continually confronted with the reality that I personally was not smart enough to keep all the information in my head that could be used to make a good decision for a patient. We have now reached a point where the amount of information that is important and useful in the practice of medicine outstrips what a human being can know. The opportunity to enable physicians with AI to remedy that situation is a good thing for doctors and, most importantly, a good thing for patients. I believe the future of medicine belongs not so much to the AI practitioner but to the AI-enabled practitioner.”

“Quick story,” added Dr. Chin. “I asked ChatGPT two questions. The first was ‘Explain the difference between Alzheimer’s and dementia’ because that’s the most common misconception in my field. And it gave me a pretty darn good answer — one I would use in a presentation with some tweaking. Then I asked it, ‘Are you a better doctor than me?’ And it replied, ‘My purpose is not to replace you, my purpose is to be supportive of you and enhance your ability.’ ”

“Quick story,” added Dr. Chin. “I asked ChatGPT two questions. The first was ‘Explain the difference between Alzheimer’s and dementia’ because that’s the most common misconception in my field. And it gave me a pretty darn good answer — one I would use in a presentation with some tweaking. Then I asked it, ‘Are you a better doctor than me?’ And it replied, ‘My purpose is not to replace you, my purpose is to be supportive of you and enhance your ability.’ ”

The second-floor operating rooms at Lehigh Valley Hospital in Allentown, Pennsylvania, are numbered sequentially — except when you get to what should be operation room (OR) 13. It’s OR M. The M doesn’t stand for Maternity or any other specialty. Rather in this high-tech, state-of-the art healthcare center, it’s there to ward off bad juju and evil spirits.

“Just as taller buildings usually don’t have a 13th floor or hotels don’t have a room 13, it revolves around the common superstition of the unlucky nature of number 13,” said a hospital spokesperson.

During the pandemic, the public was told repeatedly that modern medicine is science-based. But when I started talking to surgeons and other physicians for this article, I uncovered something decidedly unscientific.

In ORs and emergency rooms (ERs), small-town doctor’s offices, and mega hospitals, there’s a measure of dread before full moons and Friday the 13th, and no one dares utter the Q word (as in, “It sure is quiet today.”) That would risk bringing the wrath of the medical gods, and you’d earn the reputation of being a jinx or “black cloud.” Likewise, the songs “Stairway to Heaven” or “Another One Bites the Dust” will never be heard in any waiting room, elevator, or OR.

Indeed, when it comes to superstitions and rituals in medicine, it seems everyone has a story or a belief. …
 

A 2-Hour Ritual

Carmen Fong, MD, a colorectal surgeon in New York City, had a presurgical ritual that took her nearly 2 hours to complete. “I’d wake up at the same time every day, pack two hard-boiled eggs and a thermos of coffee in my small leather bag, walk to work via the same route, and swipe into the preop area while waving hi to the front desk,” she recounted. “I’d talk to the patient, sign the consent with the same ballpoint pen, go upstairs to my office, change into my scrubs [same cap and Danskos], then turn on my computer, and take a sip of coffee before heading back down to the OR. I’d always remove my badge and place it near the nurses’ workstation, then put on the patient’s SCDs [sequential compression devices] myself. I’d hold the oxygen mask while telling the patient, ‘See you later.’ Never ‘It will be okay’ or ‘Have a good sleep.’ Always ‘See you later.’ ”

Dr. Fong did this for 5 years prior to more than a thousand surgeries. She did it because it made her feel calm and in control, which translated to more successful operations. “It never failed me.”
 

Wonder Woman Clogs

Anureet Bajaj, MD, a plastic surgeon in Oklahoma City, wore Wonder Woman clogs in the OR for years because “they made me feel stronger, and my surgeries went better.” She’s also very specific about her OR playlist; “it must be ‘80s music.” And for a time, she wore a friendship bracelet that one of her employees made to commemorate getting through a particularly hard day. “If I forgot it, my heart sank, and my anxiety rose,” she said. “Wearing it gave me security and confidence that the day would go well.”

A Moment of Silence

Juliet Emamaullee, MD, PhD, is a liver and kidney transplant surgeon at Keck Hospital and Children’s Hospital Los Angeles. Because of the complexity of her operations, she must know every aspect of her patients’ medical history. This leads to a level of intimacy that most people never have with their doctors. “Transplant surgeons are playing god in many ways,” she said. “During procurement, after we prep and drape the donor and right before I make the incision, everyone in the OR has a moment of silence to acknowledge the donation. If the organ has been transported, then I’ll say a prayer to myself that I do good work with this generous gift of life.”

Magical Thinking

Before we go any further, I should clarify that there’s a difference between rituals and superstitions like the ones just shared and routines and practices such as handwashing or doublechecking that it’s the right hip and not the left. All pilots have a preflight checklist that’s necessary for safety, but some might also make the sign of the cross.

Lester Gottesman, MD, has been a surgeon at the Icahn School of Medicine at Mount Sinai Hospital in New York City for nearly 50 years. He believes rituals and superstitions are more prevalent in medicine than in any other profession, despite there being no definitive research confirming their effectiveness.

In fact, it’s the opposite.

One of the few studies to examine superstitions among physicians was published in the Annals of Surgery in 2021. Researchers analyzed the operational records of 27,914 consecutive patients who underwent general, visceral, or vascular surgery. They found no association of moon phases, zodiac signs, or Friday the 13th with poor outcomes. Having acute coronary syndrome on Friday the 13th also did not influence the 13-year mortality rate compared to other dates in the year. And although 70% of physicians believe that some colleagues are “black clouds,” an analysis of 96 physicians and 6149 admissions found no such pattern.

Granted, this is just one analysis, but the results aren’t surprising. No one really believes in this stuff. So, why does it persist?

Dr. Gottesman cited an episode from the popular medical TV show Grey’s Anatomy, in which chief surgeon Meredith Grey puts it this way: “Superstition lies in the space between what we can control and what we can’t. …We rely on superstitions because we are smart enough to know we don’t have all the answers and that life works in mysterious ways. Don’t diss the juju from wherever it comes.”

“Superstition and science both start at the same place — to explain an unexplainable event,” said Dr. Gottesman, who always checks his suture lines at the end of a surgery in the order in which he did them. “If science provides a coherent answer, so be it. If not, the human’s need for order will assign causality to otherwise inanimate objects, noncausal events, or divine influence.”

In other words, the more unknowns and trepidation, the greater the tendency toward what Dr. Gottesman called “magical thinking.” And when you consider healing’s long history, you realize that ritual and superstition defined medicine for centuries. Gottesman pointed out that it wasn’t until Hippocrates separated religion and superstition from disease around 430 BC that modern medicine was born. But because doctors still don’t know everything, an element of magic endures.

The question is, in this high-tech age, do these stubborn beliefs still have a place? Do they help or hinder doctors, and, most important, do they have any effect on patient outcomes?
 

Five Benefits

To reiterate, there are no studies showing that Wonder Woman clogs convey surgical superpowers or that eating two hard-boiled eggs boosts OR performance. But anecdotally, many doctors admit to experiencing noticeable perks from their quirks. Let’s start with the supposed benefits:

• Less stress: A quarter of US clinicians are considering switching careers, primarily due to burnout, according to a 2022 Bain survey. “The fact that [rituals and superstitions] are so prevalent in such a high-stress field can’t be coincidence,” said Dr. Fong. “Offloading some of the responsibility to whatever gods there may be is a way of taming our anxieties so we can function better.”
• Hyperfocus: Dr. Emamaullee played volleyball in high school and college. She suggested that her presurgical routine isn’t all that different from her warmup before a championship match. It’s habitual behavior that helps induce a state of heightened concentration, confidence, and immersion. Athletes call it being “in the zone” or in a “state of flow,” and Dr. Emamaullee said she experiences the same thing in the OR.
• More control: Remember those horrific images of patients with COVID-19 overwhelming ERs in Brooklyn and Queens during the pandemic? Dr. Fong was in the middle of that. “In crisis situations where there are more unknowns, rituals and superstitions become even more important,” she said. “I may not be able to control what’s happening, but I can control myself. Rituals help restore some normalcy and organization, and they give me a sense of calm.”
• Better performance: A series of general-population experiments published in the journal Psychological Science in 2010 concluded that “good-luck–related superstitions” boosted self-confidence in mastering upcoming tasks and improved motor dexterity, memory, and overall performance.
• Placebo effect: This phenomenon is well-established in medicine. Give someone a special pill or treatment, and a significant portion will claim benefit. “Placebo is magical thinking,” said Dr. Gottesman. “It has identifiable and quantifiable effects on human disease.” And perhaps on medical practitioners, too. If a doctor believes her friendship bracelet has special powers and helps her be a better physician, then it just might.

Four Drawbacks

• Compulsive behavior: When superstitious beliefs or repetitive behaviors begin causing personal distress, interfering with daily duties, or negatively affecting patient outcomes, then there’s a problem. There’s a story on Quora about a neurosurgeon who always ate two Hostess Ho Hos chocolate cakes before operations. When he forgot to do so one day, he supposedly left his patient on the table and ran off to eat them. Even if it’s urban legend, it’s a useful illustration of quirk disrupting work.
• Less flexibility: Every human body and every surgery is different. “When ritualistic behaviors or habits become so rigid that you lose the ability to adapt, then that becomes dangerous for the patient,” said Dr. Fong. “The art of medicine, not unlike jazz, often comes from the improvisation.”
• Self-fulfilling: Just as rituals and superstitions can empower and provide a sense of control, they can quickly turn on physicians who forget a part of their routine or leave their talisman on the bureau. Instead of confidence, they supply doubt. The karma becomes kryptonite.
• Avoiding responsibility: After years of friendship bracelets and Wonder Woman clogs, Dr. Bajaj is making a deliberate effort to excise magical thinking from her practice. “It can hold you back if you’re not careful,” she said. “If you start using it as a crutch when something goes wrong — like ‘Oh, I wasn’t wearing my clogs today and that’s why my flap failed’ — then you’re not doing your due diligence and figuring out what really happened.” Rather than placing the responsibility for her day going well on superstition, she’s trying to own it herself by living with more intent.

The Diagnosis

Most of the medical experts I spoke with didn’t think there was anything wrong with rituals or superstitions as long as they didn’t become compulsive or a convenient repository of blame.

“Rituals and superstitions are an acknowledgment that forces external to ourselves exist,” concluded Dr. Fong. “They’re like tiny offerings to whatever gods are out there to please be on our side. And we keep doing them because there’s a reward — better patient outcomes, which is all we want to achieve in the end. I say embrace them.”

On Oct. 5, 2022, at 10:24 a.m., Chris Nowinski, PhD, cofounder of the Boston-based Concussion Legacy Foundation (CLF), was in his home office when the email came through. For the first time, the National Institutes of Health (NIH) acknowledged there was a causal link between repeated blows to the head and chronic traumatic encephalopathy (CTE).

“I pounded my desk, shouted YES! and went to find my wife so I could pick her up and give her a big hug,” he recalled. “It was the culmination of 15 years of research and hard work.”

Robert Cantu, MD, who has been studying head trauma for 50+ years and has published more than 500 papers about it, compares the announcement to the 1964 Surgeon General’s report that linked cigarette smoking with lung cancer and heart disease. With the NIH and the Centers of Disease Control and Prevention (CDC) now in agreement about the risks of participating in impact sports and activities, he said, “We’ve reached a tipping point that should finally prompt deniers such as the NHL, NCAA, FIFA, World Rugby, the International Olympic Committee, and other [sports organizations] to remove all unnecessary head trauma from their sports.”

“A lot of the credit for this must go to Chris,” added Dr. Cantu, medical director and director of clinical research at the Cantu Concussion Center at Emerson Hospital in Concord, Mass. “Clinicians like myself can reach only so many people by writing papers and giving speeches at medical conferences. For this to happen, the message needed to get out to parents, athletes, and society in general. And Chris was the vehicle for doing that.”

Dr. Nowinski didn’t set out to be the messenger. He played football at Harvard in the late 1990s, making second-team All-Ivy as a defensive tackle his senior year. In 2000, he enrolled in Killer Kowalski’s Wrestling Institute and eventually joined Vince McMahon’s World Wrestling Entertainment (WWE).

There he played the role of 295-pound villain “Chris Harvard,” an intellectual snob who dressed in crimson tights and insulted the crowd’s IQ. “Roses are red. Violets are blue. The reason I’m talking so slowly is because no one in [insert name of town he was appearing in] has passed grade 2!”

“I’d often apply my education during a match,” he wrote in his book, “Head Games: Football’s Concussion Crisis.“ In a match in Bridgeport, Conn., I assaulted [my opponent] with a human skeleton, ripped off the skull, got down on bended knee, and began reciting Hamlet. Those were good times.”

Those good times ended abruptly, however, during a match with Bubba Ray Dudley at the Hartford Civic Center in Connecticut in 2003. Even though pro wrestling matches are rehearsed, and the blows aren’t real, accidents happen. Mr. Dudley mistakenly kicked Dr. Nowinski in the jaw with enough force to put him on his back and make the whole ring shake.

“Holy shit, kid! You okay?” asked the referee. Before a foggy Dr. Nowinski could reply, 300-pound Mr. Dudley crashed down on him, hooked his leg, and the ref began counting, “One! Two! …” Dr. Nowinski instinctively kicked out but had forgotten the rest of the script. He managed to finish the match and stagger backstage.

His coherence and awareness gradually returned, but a “throbbing headache” persisted. A locker room doctor said he might have a concussion and recommended he wait to see how he felt before wrestling in Albany, N.Y., the next evening.

The following day the headache had subsided, but he still felt “a little strange.” Nonetheless, he told the doctor he was fine and strutted out to again battle Bubba Ray, this time in a match where he eventually got thrown through a ringside table and suffered the Dudley Death Drop. Afterward, “I crawled backstage and laid down. The headache was much, much worse.”
 

An event and a process

Dr. Nowinski continued to insist he was “fine” and wrestled a few more matches in the following days before finally acknowledging something was wrong. He’d had his bell rung numerous times in football, but this was different. Even more worrisome, none of the doctors he consulted could give him any definitive answers. He finally found his way to Emerson Hospital, where Dr. Cantu was the chief of neurosurgery. 

“I remember that day vividly,” said Dr. Cantu. “Chris was this big, strapping, handsome guy – a hell of an athlete whose star was rising. He didn’t realize that he’d suffered a series of concussions and that trying to push through them was the worst thing he could be doing.”

Concussions and their effects were misunderstood by many athletes, coaches, and even physicians back then. It was assumed that the quarter inch of bone surrounding the adult brain provided adequate protection from common sports impacts and that any aftereffects were temporary. A common treatment was smelling salts and a pat on the back as the athlete returned to action.

However, the brain floats inside the skull in a bath of cerebral fluid. Any significant impact causes it to slosh violently from side to side, damaging tissue, synapses, and cells resulting in inflammation that can manifest as confusion and brain fog.

“A concussion is actually not defined by a physical injury,” explained Dr. Nowinski, “but by a loss of brain function that is induced by trauma. Concussion is not just an event, but also a process.” It’s almost as if the person has suffered a small seizure.

Fortunately, most concussion symptoms resolve within 2 weeks, but in some cases, especially if there’s been additional head trauma, they can persist, causing anxiety, depression, anger, and/or sleep disorders. Known as postconcussion syndrome (PCS), this is what Dr. Nowinski was unknowingly suffering from when he consulted Dr. Cantu.

In fact, one night it an Indianapolis hotel, weeks after his initial concussion, he awoke to find himself on the floor and the room in shambles. His girlfriend was yelling his name and shaking him. She told him he’d been having a nightmare and had suddenly started screaming and tearing up the room. “I didn’t remember any of it,” he said.

Dr. Cantu eventually advised Dr. Nowinski against ever returning to the ring or any activity with the risk for head injury. Research shows that sustaining a single significant concussion increases the risk of subsequent more-severe brain injuries.

“My diagnosis could have sent Chris off the deep end because he could no longer do what he wanted to do with this life,” said Dr. Cantu. “But instead, he used it as a tool to find meaning for his life.”

Dr. Nowinski decided to use his experience as a teaching opportunity, not just for other athletes but also for sports organizations and the medical community.

His book, which focused on the NFL’s “tobacco-industry-like refusal to acknowledge the depths of the problem,” was published in 2006. A year later, Dr. Nowinski partnered with Dr. Cantu to found the Sports Legacy Institute, which eventually became the Concussion Legacy Foundation (CLF).


 

Cold calling for brain donations

Robert Stern, PhD, is another highly respected authority in the study of neurodegenerative disease. In 2007, he was directing the clinical core of Boston University’s Alzheimer’s Disease Center. After giving a lecture to a group of financial planners and elder-law attorneys one morning, he got a request for a private meeting from a fellow named Chris Nowinski.

“I’d never heard of him, but I agreed,” recalled Dr. Stern, a professor of neurology, neurosurgery, anatomy, and neurobiology at Boston University. “A few days later, this larger-than-life guy walked into our conference room at the BU School of Medicine, exuding a great deal of passion, intellect, and determination. He told me his story and then started talking about the long-term consequences of concussions in sports.”

Dr. Stern had seen patients with dementia pugilistica, the old-school term for CTE. These were mostly boxers with cognitive and behavioral impairment. “But I had not heard about football players,” he said. “I hadn’t put the two together. And as I was listening to Chris, I realized if what he was saying was true then it was not only a potentially huge public health issue, but it was also a potentially huge scientific issue in the field of neurodegenerative disease.” 

Dr. Nowinski introduced Dr. Stern to Dr. Cantu, and together with Ann McKee, MD, professor of neurology and pathology at BU, they cofounded the Center for the Study of Traumatic Encephalopathy (CSTE) in 2008. It was the first center of its kind devoted to the study of CTE in the world.

One of Dr. Nowinski’s first jobs at the CSTE was soliciting and procuring brain donations. Since CTE is generally a progressive condition that can take decades to manifest, autopsy was the only way to detect it.

The brains of two former Pittsburgh Steelers, Mike Webster and Terry Long, had been examined after their untimely deaths. After immunostaining, investigators found both former NFL players had “protein misfolds” characteristic of CTE.

This finding drew a lot of public and scientific attention, given that Mr. Long died by suicide and Mr. Webster was homeless when he died of a heart attack. But more scientific evidence was needed to prove a causal link between the head trauma and CTE.

Dr. Nowinski scoured obituaries looking for potential brains to study. When he found one, he would cold call the family and try to convince them to donate it to science. The first brain he secured for the center belonged to John Grimsley, a former NFL linebacker who in 2008 died at age 45 of an accidental gunshot wound. Often, Dr. Nowinski would even be the courier, traveling to pick up the brain after it had been harvested.

Over the next 10 years, Dr. Nowinski and his research team secured 500 brain donations. The research that resulted was staggering. In the beginning only 45 cases of CTE had been identified in the world, but in the first 111 NFL players who were autopsied, 110 had the disorder.

Of the first 53 college football players autopsied, 48 had CTE. Although Dr. Nowinski’s initial focus was football, evidence of CTE was soon detected among athletes in boxing, hockey, soccer, and rugby, as well as in combat veterans. However, the National Football League and other governing sports bodies initially denied any connection between sport-related head trauma and CTE.
 

Cumulative damage

In 2017, after 7 years of study, Dr. Nowinski earned a PhD in neurology. As the scientific evidence continued to accumulate, two shifts occurred that Dr. Stern said represent Dr. Nowinski’s greatest contributions. First, concussion is now widely recognized as an acute brain injury with symptoms that need to be immediately diagnosed and addressed.

“This is a completely different story from where things were just 10 years ago,” said Dr. Stern, “and Chris played a central role, if not the central role, in raising awareness about that.”

All 50 states and the District of Columbia now have laws regarding sports-related concussion. And there are brain banks in Australia, Canada, New Zealand, Brazil, and the United Kingdom studying CTE. More than 2,500 athletes in a variety of sports, including NASCAR’s Dale Earnhardt Jr. and NFL hall of famer Nick Buoniconti, have publicly pledged to donate their brains to science after their deaths.

Second, said Dr. Stern, we now know that although concussions can contribute to CTE, they are not the sole cause. It’s repetitive subconcussive trauma, without symptoms of concussion, that do the most damage.

“These happen during every practice and in every game,” said Dr. Stern. In fact, it’s estimated that pro football players suffer thousands of subconcussive incidents over the course of their careers. So, a player doesn’t have to see stars or lose consciousness to suffer brain damage; small impacts can accumulate over time.

Understanding this point is crucial for making youth sports safer. “Chris has played a critical role in raising awareness here, too,” said Dr. Stern. “Allowing our kids to get hit in the head over and over can put them at greater risk for later problems, plus it just doesn’t make common sense.”

“The biggest misconception surrounding head trauma in sports,” said Dr. Nowinski, “is the belief among players, coaches, and even the medical and scientific communities that if you get hit in the head and don’t have any symptoms then you’re okay and there hasn’t been any damage. That couldn’t be further from the truth. We now know that people are suffering serious brain injuries due to the accumulated effect of subconcussive impacts, and we need to get the word out about that.”

A major initiative from the Concussion Legacy Foundation called “Stop Hitting Kids in the Head” has the goal of convincing every sport to eliminate repetitive head impacts in players under age 14 – the time when the skull and brain are still developing and most vulnerable – by 2026. In fact, Dr. Nowinski wrote that “there could be a lot of kids who are misdiagnosed and medicated for various behavioral or emotional problems that may actually be head injury–related.”

Starting in 2009, the NFL adopted a series of rule changes designed to better protect its players against repeated head trauma. Among them is a ban on spearing or leading with the helmet, penalties for hitting defenseless players, and more stringent return-to-play guidelines, including concussion protocols.

The NFL has also put more emphasis on flag football options for youngsters and, for the first time, showcased this alternative in the 2023 Pro Bowl. But Dr. Nowinski is pressuring the league to go further. “While acknowledging that the game causes CTE, the NFL still underwrites recruiting 5-year-olds to play tackle football,” he said. “In my opinion, that’s unethical, and it needs to be addressed.”
 

WWE one of the most responsive organizations

Dr. Nowinski said WWE has been one of the most responsive sports organizations for protecting athletes. A doctor is now ringside at every match as is an observer who knows the script, thereby allowing for instant medical intervention if something goes wrong. “Since everyone is trying to look like they have a concussion all the time, it takes a deep understanding of the business to recognize a real one,” he said.

But this hasn’t been the case with other sports. “I am eternally disappointed in the response of the professional sports industry to the knowledge of CTE and long-term concussion symptoms,” said Dr. Nowinski.

“For example, FIFA [international soccer’s governing body] still doesn’t allow doctors to evaluate [potentially concussed] players on the sidelines and put them back in the game with a free substitution [if they’re deemed okay]. Not giving players proper medical care for a brain injury is unethical,” he said. BU’s Center for the Study of Traumatic Encephalopathy diagnosed the first CTE case in soccer in 2012, and in 2015 Dr. Nowinski successfully lobbied U.S. Soccer to ban heading the ball before age 11.

“Unfortunately, many governing bodies have circled the wagons in denying their sport causes CTE,” he continued. “FIFA, World Rugby, the NHL, even the NCAA and International Olympic Committee refuse to acknowledge it and, therefore, aren’t taking any steps to prevent it. They see it as a threat to their business model. Hopefully, now that the NIH and CDC are aligned about the risks of head impact in sports, this will begin to change.”

Meanwhile, research is continuing. Scientists are getting closer to being able to diagnose CTE in living humans, with ongoing studies using PET scans, blood markers, and spinal fluid markers. In 2019, researchers identified tau proteins specific to CTE that they believe are distinct from those of Alzheimer’s and other neurodegenerative diseases. Next step would be developing a drug to slow the development of CTE once detected.

Nonetheless, athletes at all levels in impact sports still don’t fully appreciate the risks of repeated head trauma and especially subconcussive blows. “I talk to former NFL and college players every week,” said Dr. Stern. “Some tell me, ‘I love the sport, it gave me so much, and I would do it again, but I’m not letting my grandchildren play.’ But others say, ‘As long as they know the risks, they can make their own decision.’ “

Dr. Nowinski has a daughter who is 4 and a son who’s 2. Both play soccer but, thanks to dad, heading isn’t allowed in their age groups. If they continue playing sports, Dr. Nowinski said he’ll make sure they understand the risks and how to protect themselves. This is a conversation all parents should have with their kids at every level to make sure they play safe, he added.

Those in the medical community can also volunteer their time to explain head trauma to athletes, coaches, and school administrators to be sure they understand its seriousness and are doing everything to protect players.

As you watch this year’s Super Bowl, Dr. Nowinski and his team would like you to keep something in mind. Those young men on the field for your entertainment are receiving mild brain trauma repeatedly throughout the game.

Even if it’s not a huge hit that gets replayed and makes everyone gasp, even if no one gets ushered into the little sideline tent for a concussion screening, even if no one loses consciousness, brain damage is still occurring. Watch the heads of the players during every play and think about what’s going on inside their skulls regardless of how big and strong those helmets look.

On Oct. 5, 2022, at 10:24 a.m., Chris Nowinski, PhD, cofounder of the Boston-based Concussion Legacy Foundation (CLF), was in his home office when the email came through. For the first time, the National Institutes of Health (NIH) acknowledged there was a causal link between repeated blows to the head and chronic traumatic encephalopathy (CTE).

“I pounded my desk, shouted YES! and went to find my wife so I could pick her up and give her a big hug,” he recalled. “It was the culmination of 15 years of research and hard work.”

Robert Cantu, MD, who has been studying head trauma for 50+ years and has published more than 500 papers about it, compares the announcement to the 1964 Surgeon General’s report that linked cigarette smoking with lung cancer and heart disease. With the NIH and the Centers of Disease Control and Prevention (CDC) now in agreement about the risks of participating in impact sports and activities, he said, “We’ve reached a tipping point that should finally prompt deniers such as the NHL, NCAA, FIFA, World Rugby, the International Olympic Committee, and other [sports organizations] to remove all unnecessary head trauma from their sports.”

“A lot of the credit for this must go to Chris,” added Dr. Cantu, medical director and director of clinical research at the Cantu Concussion Center at Emerson Hospital in Concord, Mass. “Clinicians like myself can reach only so many people by writing papers and giving speeches at medical conferences. For this to happen, the message needed to get out to parents, athletes, and society in general. And Chris was the vehicle for doing that.”

“I’d often apply my education during a match,” he wrote in his book, “Head Games: Football’s Concussion Crisis.“ In a match in Bridgeport, Conn., I assaulted [my opponent] with a human skeleton, ripped off the skull, got down on bended knee, and began reciting Hamlet. Those were good times.”

Those good times ended abruptly, however, during a match with Bubba Ray Dudley at the Hartford Civic Center in Connecticut in 2003. Even though pro wrestling matches are rehearsed, and the blows aren’t real, accidents happen. Mr. Dudley mistakenly kicked Dr. Nowinski in the jaw with enough force to put him on his back and make the whole ring shake.

“Holy shit, kid! You okay?” asked the referee. Before a foggy Dr. Nowinski could reply, 300-pound Mr. Dudley crashed down on him, hooked his leg, and the ref began counting, “One! Two! …” Dr. Nowinski instinctively kicked out but had forgotten the rest of the script. He managed to finish the match and stagger backstage.

His coherence and awareness gradually returned, but a “throbbing headache” persisted. A locker room doctor said he might have a concussion and recommended he wait to see how he felt before wrestling in Albany, N.Y., the next evening.

The following day the headache had subsided, but he still felt “a little strange.” Nonetheless, he told the doctor he was fine and strutted out to again battle Bubba Ray, this time in a match where he eventually got thrown through a ringside table and suffered the Dudley Death Drop. Afterward, “I crawled backstage and laid down. The headache was much, much worse.”
 

An event and a process

Dr. Nowinski continued to insist he was “fine” and wrestled a few more matches in the following days before finally acknowledging something was wrong. He’d had his bell rung numerous times in football, but this was different. Even more worrisome, none of the doctors he consulted could give him any definitive answers. He finally found his way to Emerson Hospital, where Dr. Cantu was the chief of neurosurgery. 

“I remember that day vividly,” said Dr. Cantu. “Chris was this big, strapping, handsome guy – a hell of an athlete whose star was rising. He didn’t realize that he’d suffered a series of concussions and that trying to push through them was the worst thing he could be doing.”

Concussions and their effects were misunderstood by many athletes, coaches, and even physicians back then. It was assumed that the quarter inch of bone surrounding the adult brain provided adequate protection from common sports impacts and that any aftereffects were temporary. A common treatment was smelling salts and a pat on the back as the athlete returned to action.

However, the brain floats inside the skull in a bath of cerebral fluid. Any significant impact causes it to slosh violently from side to side, damaging tissue, synapses, and cells resulting in inflammation that can manifest as confusion and brain fog.

“A concussion is actually not defined by a physical injury,” explained Dr. Nowinski, “but by a loss of brain function that is induced by trauma. Concussion is not just an event, but also a process.” It’s almost as if the person has suffered a small seizure.

Fortunately, most concussion symptoms resolve within 2 weeks, but in some cases, especially if there’s been additional head trauma, they can persist, causing anxiety, depression, anger, and/or sleep disorders. Known as postconcussion syndrome (PCS), this is what Dr. Nowinski was unknowingly suffering from when he consulted Dr. Cantu.

In fact, one night it an Indianapolis hotel, weeks after his initial concussion, he awoke to find himself on the floor and the room in shambles. His girlfriend was yelling his name and shaking him. She told him he’d been having a nightmare and had suddenly started screaming and tearing up the room. “I didn’t remember any of it,” he said.

Dr. Cantu eventually advised Dr. Nowinski against ever returning to the ring or any activity with the risk for head injury. Research shows that sustaining a single significant concussion increases the risk of subsequent more-severe brain injuries.

“My diagnosis could have sent Chris off the deep end because he could no longer do what he wanted to do with this life,” said Dr. Cantu. “But instead, he used it as a tool to find meaning for his life.”

Dr. Nowinski decided to use his experience as a teaching opportunity, not just for other athletes but also for sports organizations and the medical community.

His book, which focused on the NFL’s “tobacco-industry-like refusal to acknowledge the depths of the problem,” was published in 2006. A year later, Dr. Nowinski partnered with Dr. Cantu to found the Sports Legacy Institute, which eventually became the Concussion Legacy Foundation (CLF).


 

Cold calling for brain donations

Robert Stern, PhD, is another highly respected authority in the study of neurodegenerative disease. In 2007, he was directing the clinical core of Boston University’s Alzheimer’s Disease Center. After giving a lecture to a group of financial planners and elder-law attorneys one morning, he got a request for a private meeting from a fellow named Chris Nowinski.

“I’d never heard of him, but I agreed,” recalled Dr. Stern, a professor of neurology, neurosurgery, anatomy, and neurobiology at Boston University. “A few days later, this larger-than-life guy walked into our conference room at the BU School of Medicine, exuding a great deal of passion, intellect, and determination. He told me his story and then started talking about the long-term consequences of concussions in sports.”

Dr. Stern had seen patients with dementia pugilistica, the old-school term for CTE. These were mostly boxers with cognitive and behavioral impairment. “But I had not heard about football players,” he said. “I hadn’t put the two together. And as I was listening to Chris, I realized if what he was saying was true then it was not only a potentially huge public health issue, but it was also a potentially huge scientific issue in the field of neurodegenerative disease.” 

Dr. Nowinski introduced Dr. Stern to Dr. Cantu, and together with Ann McKee, MD, professor of neurology and pathology at BU, they cofounded the Center for the Study of Traumatic Encephalopathy (CSTE) in 2008. It was the first center of its kind devoted to the study of CTE in the world.

One of Dr. Nowinski’s first jobs at the CSTE was soliciting and procuring brain donations. Since CTE is generally a progressive condition that can take decades to manifest, autopsy was the only way to detect it.

The brains of two former Pittsburgh Steelers, Mike Webster and Terry Long, had been examined after their untimely deaths. After immunostaining, investigators found both former NFL players had “protein misfolds” characteristic of CTE.

This finding drew a lot of public and scientific attention, given that Mr. Long died by suicide and Mr. Webster was homeless when he died of a heart attack. But more scientific evidence was needed to prove a causal link between the head trauma and CTE.

Dr. Nowinski scoured obituaries looking for potential brains to study. When he found one, he would cold call the family and try to convince them to donate it to science. The first brain he secured for the center belonged to John Grimsley, a former NFL linebacker who in 2008 died at age 45 of an accidental gunshot wound. Often, Dr. Nowinski would even be the courier, traveling to pick up the brain after it had been harvested.

Over the next 10 years, Dr. Nowinski and his research team secured 500 brain donations. The research that resulted was staggering. In the beginning only 45 cases of CTE had been identified in the world, but in the first 111 NFL players who were autopsied, 110 had the disorder.

Of the first 53 college football players autopsied, 48 had CTE. Although Dr. Nowinski’s initial focus was football, evidence of CTE was soon detected among athletes in boxing, hockey, soccer, and rugby, as well as in combat veterans. However, the National Football League and other governing sports bodies initially denied any connection between sport-related head trauma and CTE.
 

Cumulative damage

In 2017, after 7 years of study, Dr. Nowinski earned a PhD in neurology. As the scientific evidence continued to accumulate, two shifts occurred that Dr. Stern said represent Dr. Nowinski’s greatest contributions. First, concussion is now widely recognized as an acute brain injury with symptoms that need to be immediately diagnosed and addressed.

“This is a completely different story from where things were just 10 years ago,” said Dr. Stern, “and Chris played a central role, if not the central role, in raising awareness about that.”

All 50 states and the District of Columbia now have laws regarding sports-related concussion. And there are brain banks in Australia, Canada, New Zealand, Brazil, and the United Kingdom studying CTE. More than 2,500 athletes in a variety of sports, including NASCAR’s Dale Earnhardt Jr. and NFL hall of famer Nick Buoniconti, have publicly pledged to donate their brains to science after their deaths.

Second, said Dr. Stern, we now know that although concussions can contribute to CTE, they are not the sole cause. It’s repetitive subconcussive trauma, without symptoms of concussion, that do the most damage.

“These happen during every practice and in every game,” said Dr. Stern. In fact, it’s estimated that pro football players suffer thousands of subconcussive incidents over the course of their careers. So, a player doesn’t have to see stars or lose consciousness to suffer brain damage; small impacts can accumulate over time.

Understanding this point is crucial for making youth sports safer. “Chris has played a critical role in raising awareness here, too,” said Dr. Stern. “Allowing our kids to get hit in the head over and over can put them at greater risk for later problems, plus it just doesn’t make common sense.”

“The biggest misconception surrounding head trauma in sports,” said Dr. Nowinski, “is the belief among players, coaches, and even the medical and scientific communities that if you get hit in the head and don’t have any symptoms then you’re okay and there hasn’t been any damage. That couldn’t be further from the truth. We now know that people are suffering serious brain injuries due to the accumulated effect of subconcussive impacts, and we need to get the word out about that.”

A major initiative from the Concussion Legacy Foundation called “Stop Hitting Kids in the Head” has the goal of convincing every sport to eliminate repetitive head impacts in players under age 14 – the time when the skull and brain are still developing and most vulnerable – by 2026. In fact, Dr. Nowinski wrote that “there could be a lot of kids who are misdiagnosed and medicated for various behavioral or emotional problems that may actually be head injury–related.”

Starting in 2009, the NFL adopted a series of rule changes designed to better protect its players against repeated head trauma. Among them is a ban on spearing or leading with the helmet, penalties for hitting defenseless players, and more stringent return-to-play guidelines, including concussion protocols.

The NFL has also put more emphasis on flag football options for youngsters and, for the first time, showcased this alternative in the 2023 Pro Bowl. But Dr. Nowinski is pressuring the league to go further. “While acknowledging that the game causes CTE, the NFL still underwrites recruiting 5-year-olds to play tackle football,” he said. “In my opinion, that’s unethical, and it needs to be addressed.”
 

WWE one of the most responsive organizations

Dr. Nowinski said WWE has been one of the most responsive sports organizations for protecting athletes. A doctor is now ringside at every match as is an observer who knows the script, thereby allowing for instant medical intervention if something goes wrong. “Since everyone is trying to look like they have a concussion all the time, it takes a deep understanding of the business to recognize a real one,” he said.

But this hasn’t been the case with other sports. “I am eternally disappointed in the response of the professional sports industry to the knowledge of CTE and long-term concussion symptoms,” said Dr. Nowinski.

“For example, FIFA [international soccer’s governing body] still doesn’t allow doctors to evaluate [potentially concussed] players on the sidelines and put them back in the game with a free substitution [if they’re deemed okay]. Not giving players proper medical care for a brain injury is unethical,” he said. BU’s Center for the Study of Traumatic Encephalopathy diagnosed the first CTE case in soccer in 2012, and in 2015 Dr. Nowinski successfully lobbied U.S. Soccer to ban heading the ball before age 11.

“Unfortunately, many governing bodies have circled the wagons in denying their sport causes CTE,” he continued. “FIFA, World Rugby, the NHL, even the NCAA and International Olympic Committee refuse to acknowledge it and, therefore, aren’t taking any steps to prevent it. They see it as a threat to their business model. Hopefully, now that the NIH and CDC are aligned about the risks of head impact in sports, this will begin to change.”

Meanwhile, research is continuing. Scientists are getting closer to being able to diagnose CTE in living humans, with ongoing studies using PET scans, blood markers, and spinal fluid markers. In 2019, researchers identified tau proteins specific to CTE that they believe are distinct from those of Alzheimer’s and other neurodegenerative diseases. Next step would be developing a drug to slow the development of CTE once detected.

Nonetheless, athletes at all levels in impact sports still don’t fully appreciate the risks of repeated head trauma and especially subconcussive blows. “I talk to former NFL and college players every week,” said Dr. Stern. “Some tell me, ‘I love the sport, it gave me so much, and I would do it again, but I’m not letting my grandchildren play.’ But others say, ‘As long as they know the risks, they can make their own decision.’ “

Dr. Nowinski has a daughter who is 4 and a son who’s 2. Both play soccer but, thanks to dad, heading isn’t allowed in their age groups. If they continue playing sports, Dr. Nowinski said he’ll make sure they understand the risks and how to protect themselves. This is a conversation all parents should have with their kids at every level to make sure they play safe, he added.

Those in the medical community can also volunteer their time to explain head trauma to athletes, coaches, and school administrators to be sure they understand its seriousness and are doing everything to protect players.

As you watch this year’s Super Bowl, Dr. Nowinski and his team would like you to keep something in mind. Those young men on the field for your entertainment are receiving mild brain trauma repeatedly throughout the game.

Even if it’s not a huge hit that gets replayed and makes everyone gasp, even if no one gets ushered into the little sideline tent for a concussion screening, even if no one loses consciousness, brain damage is still occurring. Watch the heads of the players during every play and think about what’s going on inside their skulls regardless of how big and strong those helmets look.
