TOPLINE:

Depression is linked to a significantly increased risk for cardiovascular disease (CVD), particularly in women, new data from a large retrospective cohort study show. Researchers suggest that screening and treating patients for depression may lead to a decreased incidence of CVD.

METHODOLOGY:

• Researchers analyzed health insurance claims from more than 4 million Japanese patients filed between 2005 and 2022.
• Participants were 18-75 (median age, 44) without a history of CVD or stroke, heart failure, or atrial fibrillation.
• Investigators followed participants for a mean period of 2.5-3.5 years to observe the number of CVD events in those who had a diagnosis of depression.
• During the follow-up period, there were 119,000 CVD events in men (14 per 10,000 person-years) and 61,800 CVD events in women (111 per 10,000 person-years).

TAKEAWAY:

• Compared with women without depression, those with depression had a 64% higher risk for CVD (hazard ratio [HR], 1.64), while men with depression had a 39% higher risk for CVD vs their counterparts without depression (HR, 1.39; P < .001).
• This association was significant even after controlling for various factors such as body mass index, diabetes, smoking, alcohol consumption, and physical inactivity.
• Investigators offered several theories about the increased risk for CVD in women with depression, including how depression during hormonal shifts can contribute to a greater impact on cardiovascular health.

IN PRACTICE:

“Healthcare professionals must recognize the important role of depression in the development of CVD and emphasize the importance of a comprehensive, patient-centered approach to its prevention and management,” study author Hidehiro Kaneko, MD, said in a press release. “Assessing the risk of CVD in depressed patients and treating and preventing depression may lead to a decrease of CVD cases.”

SOURCE:

Keitaro Senoo, MD, of the Kyoto Prefectural University of Medicine, Kyoto, Japan, led the study, which was published online on March 12 in JACC: Asia.

LIMITATIONS:

The study is observational, so causality between depression and subsequent CVD events cannot be established. In addition, depression severity is unknown.

DISCLOSURES:

The study was funded by the Ministry of Health, Labour, and Welfare, Japan, and the Ministry of Education, Culture, Sports, Science, and Technology, Japan. There were no disclosures reported.

Skipping meals, mood and anxiety disorders, as well as vaping and substance use, all raise the risk for frequent recurrent headaches in children and adolescents, new data from a population-based study showed.

Children and teens with anxiety or mood disorders had twice the risk for frequent headaches, defined as occurring once or more per week, and those who regularly ate breakfast and dinners with their family had an 8% lower risk for frequent headaches than those who did not eat regular meals.

“It is not uncommon for children and teens to have headaches, and while medications are used to stop and sometimes prevent headaches, lifestyle changes also may offer an effective route to relief by preventing headaches from happening and improving quality of life,” study investigator Serena L. Orr, MD, MSc, University of Calgary in Alberta, Canada, said in a press release.

The findings were published online in Neurology.
 

Negative Consequences

Previous research shows frequent recurrent headaches occur in up to 30% of children and adolescents and can lead to lower academic achievement and lower quality of life.

Treatment recommendations often focus on adjusting lifestyle behaviors, such as sleep and meal timing or smoking.

To further investigate these links, researchers used data from the 2019 Canadian Health Survey on Children and Youth and included about 5 million children and teens aged 5-17 years. In most cases, a parent or guardian answered the survey questions.

In addition to assessing participants for headache frequency in the past week, the survey included questions about how often they had breakfast, were physically active, or spent playing video games or with a mobile device, for instance. Parents/guardians were also asked whether the youth had ever been diagnosed with a mood or anxiety disorder.

For participants aged between 12 and 17 years, there were also questions about smoking, alcohol consumption, and substance use.

The mean age of participants was 11 years, and 48% were female. About 6% of the participants had frequent recurrent headaches.

Investigators found that meal regularity was inversely associated with frequent headaches (P < .001). In an adjusted model, youth who often ate breakfast and dinner with their families had an 8% lower risk for frequent headaches than those who didn’t dine with their families regularly.

“It is possible regular family meals may lead to greater connectedness and communication within the family and better mental health outcomes, which in turn may impact headache frequency,” Dr. Orr noted.

Youth who spent more than 21 hours per week in front of computer screens or with video games had higher odds for frequent headaches (P < .001), but this association did not survive statistical adjustment for demographics or lifestyle factors.

Both mood and anxiety disorders were associated with twice the risk for frequent headaches, and this risk survived adjustment for age, sex, household income, and other lifestyle factors.

In adolescents aged 12-17 years, there was an association between drinking alcohol and frequent headache, with higher alcohol consumption increasing the likelihood of frequent headache. For instance, those who drank once or more per week had three times the risk for frequent headache (P < .001), and those who indulged in binge drinking at least five times per month had five times the risk for frequent headache (P < .001).

Smoking cannabis was also associated with frequent headache in a dose-dependent manner. Daily users had a threefold increased risk for frequent headache vs those who didn’t use cannabis (P < .001).

Similarly, those who smoked or used e-cigarettes daily also had a threefold increased risk for frequent headaches versus nonusers.

One of the study’s limitations was that it didn’t include participants living in foster homes, institutions or on First Nation reserves. Investigators also were not able to determine headache type and did not assess hydration, which can be an important lifestyle factor in headache etiology.
 

Prioritize Questions About Lifestyle?

In an accompanying editorial, Irene Patniyot, MD, of Baylor College of Medicine in Houston, Texas, noted that lifestyle advice is an important part of managing headache disorders in children and youth and questioned whether neurologists should prioritize discussions about lifestyle habits in this patient population. However, she noted, given the heavy demands on neurologists’ time, this may be “idealistic.”

One potential solution may lie in automating electronic questionnaires for inclusion in patients’ medical records. “Data extraction from electronic questionnaires has already led to new data on symptoms associated with headache in youth and can potentially lead to earlier identification and treatment of mental health disorders and lifestyle habits that negatively affect headache burden and overall well-being,” Dr. Patniyot wrote.

The study was funded by the Social Sciences and Humanities Research Council of Canada, the Canadian Institutes of Health Research, the Canada Foundation for Innovation, and Statistics Canada. Dr. Orr reported receiving royalties from Cambridge University Press; serving on the editorial boards of Headache, Neurology, and the American Migraine Foundation; and receiving research funding from the Canadian Institutes of Health Research and the Alberta Children’s Hospital Research Institute. Other disclosures were noted in the original article.

Epilepsy was linked to a significantly increased the risk for hospitalization and death from COVID-19 early in the pandemic, while healthcare utilization rates in this patient population declined, data from two linked studies showed. 

Results showed that individuals with epilepsy had a 60% higher risk for hospitalization and a 33% higher risk of dying from COVID-19 than those without the disorder. However, during the pandemic, the number of hospitalizations and ER visits by people with epilepsy dropped by as much as 30%. 

“The neurotropic effects of Sars-CoV-2 might explain some of this increased risk for people with epilepsy, or epilepsy might be associated with alterations in the immune system, predisposing to more severe COVID-19,” wrote the investigators, led by Owen Pickrell, MBBChirm, PhD, Swansea University, United Kingdom.

The findings were published online March 5 in Epilepsia. 
 

Skill Shifting 

Epilepsy is one of the most common neurological conditions and affects approximately 50 million people worldwide, with significant comorbidity and an increased risk for early death.

During the pandemic, clinicians treating people with epilepsy and other conditions shifted their skills to treat an ever-increasing number of patients with COVID-19, which may have hindered epilepsy-specific services for a time.

To further explore how the COVID-19 pandemic may have affected the health of this patient population, researchers analyzed health records from a large database with information about hospital admissions, primary care visits, COVID-19 vaccination status, and demographics of 90% of Welsh residents.

Those living with epilepsy before or during the study period (March 1, 2020, to June 31, 2021) were identified and compared with controls without epilepsy. 

The analysis included approximately 27,280 people with epilepsy and 136,400 matched controls. Among those with epilepsy, there were 158 deaths (0.58%) and 933 hospitalizations (3.4%). In comparison, there were 370 deaths (0.27%) and 1871 hospitalizations (1.4%) in the control group.

Unadjusted analyses showed the risk of dying from COVID-19 for those with epilepsy vs controls was more than twofold higher (hazard ratio [HR], 2.15; 95% CI; 1.78-2.59) and the increase in the risk for hospitalization was similar (HR, 2.15; 95% CI; 1.94-2.37). 

After adjusting for 40 comorbidities, including serious mental illness, asthma, and diabetes, those with epilepsy had a 60% increased risk for hospitalization (adjusted HR [aHR], 1.60) and a 33% increased risk for death (aHR, 1.33) than those without epilepsy (all P < .0001). 

The findings “may have implications for prioritizing future COVID-19 treatments and vaccinations for people with epilepsy,” the investigators wrote.

Study limitations included the inability to account for the effect of vaccinations or prior infections with SARS-CoV-2. Moreover, the study did not account for geographical or temporal variations in prevalence and COVID-19 variants. 
 

Consultations Canceled 

In the related study, researchers analyzed healthcare utilization by people with epilepsy before and after the pandemic using the same database. Results showed hospital admissions, ER visits, and outpatient visits significantly decreased during the pandemic. 

In the year before the pandemic, people with epilepsy had double the rate of ER visits (rate ratio [RR], 2.36), hospital admissions (RR, 2.08), and outpatient appointments (RR, 1.92) compared with matched controls. 

However, during the pandemic there was a greater reduction in hospital admissions (RR, 0.70; 95% CI, 0.69-0.72) and ER visits (RR, 0.78; 95% CI, 0.77-0.70) in those with epilepsy versus matched controls (RR, 0.82; 95% CI, 0.81-0.83) as well as hospital visits and ER visits (RR, 0.87; 95% CI, 0.86-0.88; all P < .0001). New epilepsy diagnoses also decreased during the pandemic (RR, 0.73; P < .0001)

The redeployment of epileptologists during the pandemic also meant that epilepsy consultations and investigations were canceled, making it harder for people with epilepsy to access specialty care, the researchers noted. 

“Our research also showed that there were fewer new diagnoses of epilepsy and fewer contacts with health services by people with epilepsy, during the period we examined,” Huw Strafford, lead data analyst for the studies, said in a release.

Both studies were funded by Health and Care Research Wales. Dr. Pickrell reported receiving speaker fees from UCB Pharma and Angelini Pharma, travel grants from Angelini Pharma, and an unrestricted grant from UCB Pharma.

In the related study, researchers analyzed healthcare utilization by people with epilepsy before and after the pandemic using the same database. Results showed hospital admissions, ER visits, and outpatient visits significantly decreased during the pandemic. 

In the year before the pandemic, people with epilepsy had double the rate of ER visits (rate ratio [RR], 2.36), hospital admissions (RR, 2.08), and outpatient appointments (RR, 1.92) compared with matched controls. 

However, during the pandemic there was a greater reduction in hospital admissions (RR, 0.70; 95% CI, 0.69-0.72) and ER visits (RR, 0.78; 95% CI, 0.77-0.70) in those with epilepsy versus matched controls (RR, 0.82; 95% CI, 0.81-0.83) as well as hospital visits and ER visits (RR, 0.87; 95% CI, 0.86-0.88; all P < .0001). New epilepsy diagnoses also decreased during the pandemic (RR, 0.73; P < .0001)

The redeployment of epileptologists during the pandemic also meant that epilepsy consultations and investigations were canceled, making it harder for people with epilepsy to access specialty care, the researchers noted. 

“Our research also showed that there were fewer new diagnoses of epilepsy and fewer contacts with health services by people with epilepsy, during the period we examined,” Huw Strafford, lead data analyst for the studies, said in a release.

Both studies were funded by Health and Care Research Wales. Dr. Pickrell reported receiving speaker fees from UCB Pharma and Angelini Pharma, travel grants from Angelini Pharma, and an unrestricted grant from UCB Pharma.

Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.

Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.

“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam, Rotterdam, the Netherlands, said in a press release.

The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Ms. Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.

“The tasks that these dogs perform, along with their companionship, may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.

The findings were published online in Neurology.
 

Improve Quality of Life

The study included 25 individuals with medically refractory epilepsy who had an average of two or more seizures per week, with seizure characteristics associated with a high risk for injuries or dysfunction. They also had to be able to care for a service dog.

All were observed under usual care, which included antiseizure medications, neurostimulation devices, and other supportive therapies. Participants could then choose to work with a service dog that had completed socialization and obedience training or be assigned a puppy they would train at home.

The median follow-up was 19 months with usual care and 12 months with the intervention. Participants recorded seizure activity in diaries and completed surveys on seizure severity, quality of life, and well-being every 3 months. Daily seizure counts were converted to obtain cumulative seizure frequencies over 28-day periods.

Of the 25 original participants, six discontinued trial participation before the end of follow-up, four of whom left the study due to difficulty with dog care and training.

Participants receiving usual care reported an average of 115 seizures per 28-day period, while those with trained service dogs recorded 73 seizures in the same period, or a 37% difference between groups.

Researchers found that participants had an average of 31% fewer seizures during the past 3 months when they had seizure dogs, with seven participants achieving a 50%-100% reduction in seizures.

The number of seizure-free days increased from an average of 11 days per 28-day period before receiving a service dog to 15 days after working with a dog.

Scores on the EQ-5D-5L, which measures perceived health problems, decreased on average by 2.5% per consecutive 28-day period with the intervention, reflecting an increase in generic health-related quality of life (0.975; 95% CI, 0.954-0.997).

“These findings show that seizure dogs can help people with epilepsy,” said Ms. van Hezik-Wester. “However, we also found that this partnership with seizure dogs might not be the right fit for everyone, as some people discontinued their participation in this program. More research is needed to better understand which people can benefit from working with seizure dogs.”
 

Enhanced Quality of Life

In an accompanying editorial, Amir Mbonde, MB, and Amy Crepeau, MD, of Mayo Clinic in Phoenix, Arizona, noted the findings add to a growing body of work on the effectiveness of service dogs in reducing seizure frequency.

“In addition to improved seizure control, the EPISODE study demonstrated the benefit of seizure dogs in enhancing the quality of life for patients, a crucial component of comprehensive epilepsy care,” they wrote.

In prior studies, seizure dogs have identified an odor that a person emits before a seizure in up to 97% of people, they noted, adding that this ability “offers immense clinical benefits to people with epilepsy, enhancing their independence, social engagement, employment opportunities, self-confidence, and thus quality of life.”

Study limitations include its small sample size and high attrition rate.

The study was funded by the Netherlands Organization for Health Research and Development and Innovatiefonds Zorgverzekeraars.

TOPLINE:

Exposure to more traffic-related air pollution is associated with greater levels of amyloid plaques in the brain, with exposure in the 3 years before death having the greatest risk, a new postmortem study showed.

METHODOLOGY:

• Investigators examined the brain tissue of 224 people living in the Atlanta area who agreed to donate their brains after death (average age of death, 76 years) for the presence of amyloid plaques and tau tangles.
• They also studied the amount of fine particulate matter < 2.5 microns (PM2.5) from traffic-related air pollution at participants’ home addresses at 1, 3, and 5 years before death.
• The presence of the APOE e4 gene was examined for evidence of any effect on the relationship between air pollution and evidence of Alzheimer’s disease (AD).

TAKEAWAY: 

The average level of exposure in the year before death was 1.32 µg/m³ and 1.35 µg/m³ in the 3 years before death.

People with 1 µg/m³ higher PM2.5 exposure in the year before death were nearly twice as likely to have higher levels of plaques (odds ratio [OR], 1.92; 95% CI, 1.12-3.30), while those with higher exposure in the 3 years before death were 87% more likely to have higher levels of plaques (OR, 1.87; 95% CI, 1.01-3.17).

A little more than half (56%) of the sample were positive for the APOE e4 genotype, but the strongest association between pollution and neuropathology markers was for noncarriers of the genotype, although this relationship did not reach statistical significance.

IN PRACTICE:

“More research is needed to establish causality for the association between PM2.5 and AD, including epidemiologic and mechanistic studies. Future studies should also investigate the association between PM2.5 and other dementia-related pathologies, including cerebrovascular pathology,” the study authors wrote. 

SOURCE:

Anke Hüls, PhD, of Emory University in Atlanta, led the study, which was published online on February 21, 2024, in Neurology.

LIMITATIONS:

The sample was not population-based but a convenience sample composed mostly of highly educated White participants.

DISCLOSURES:

The study was funded by the National Institute of Environmental Health Sciences, the Goizueta Alzheimer’s Disease Research Center, the National Institute on Aging, and the National Institutes of Health. There were no relevant disclosures.

TOPLINE:

Scents that trigger specific, vivid autobiographical memories (AMs) could improve deficits in memory recall in patients with major depressive disorder (MDD), new research suggests. Investigators found that odor cues may be a stronger tool than word cues for improving memory, which could help reduce MDD symptoms.

METHODOLOGY:

• Participants included 32 individuals aged 18-55 years (mean age, 30 years; 26 females) with a diagnosis of MDD recruited from the community.
• Those with psychosis, bipolar I or II, neurological disorders, or drug or alcohol abuse were excluded.
• Participants were presented with a series of 12 words and 12 odors, such as cough syrup, tobacco ash, and Vicks VapoRub, and asked to recall a specific memory in response to each cue.
• AMs were rated in terms of vividness, frequency, and whether they were associated with positive or negative emotions.

TAKEAWAY:

• Although participants only guessed correct stimulus odors 30% of the time, they recalled more specific memories from odor cues than from word cues (68% vs 52%; P < .001).
• Odor-cued recall was more arousing and vivid (P < .001) than recall responses generated by word cues.
• Compared with the population mean for responses to word cues in healthy controls, study participants recalled fewer specific memories in response to words (P < .001), but the percentage of specific memories recalled in response to odor cues did not differ from the healthy control population mean.
• Investigators hoped to further their research by investigating the mechanisms underlying odor-cued AMs, particularly to test if the amygdala and hippocampus are activated during recall.

IN PRACTICE:

“This study suggests the potential for increasing autobiographical memory specificity in individuals with MDD, with the future goal of reducing depression symptoms for this population and informing a better understanding of the neural mechanisms influencing odor-based AM recall,” the authors wrote. “We hope this initial study spurs larger studies in more diverse samples that include healthy control participants to further investigate and explain these associations.”

TOPLINE:

Playing a musical instrument is associated with better working memory and executive function, and singing in a group is associated with better executive function, new study results showed.

METHODOLOGY:

• This was a nested study within PROTECT-UK, a longitudinal cohort study designed to examine aging and brain health. Participants completed three tests for working memory and one for executive function up to three times a year between 2019 and 2022.
• A group of 1107 participants (83% female; mean age 68 years) completed the Edinburgh Lifetime Musical Experience Questionnaire, which posed questions about playing musical instruments, singing, listening to music, and self-reported musical ability.
• Participants were split into two groups, namely, those who reported singing or playing a musical instrument (89%) or not (11%), and compared.

TAKEAWAY:

• Participants who reported playing a musical instrument performed significantly better on working memory (P < .0001) and executive function tasks (P < .0005) than those who didn’t play an instrument.
• The effect on working memory was the most heightened in those who reported playing keyboard (P < .0001), while those who played a woodwind instrument (P < .04) and/or sang (P < .014) showed significantly better performance on the executive function task.
• Nearly 90% of the sample had experience playing a musical instrument, with 44% playing currently. The majority of participants reported playing either one (28%) or two (23%) instruments.

IN PRACTICE:

Public health interventions might promote dementia risk reduction by incorporating music into programming, the authors concluded. “There is considerable evidence for the benefit of music group activities for individuals with dementia, and this approach could be extended as part of a health aging package for healthy older adults to enable them to proactively reduce their risk and to promote brain health,” they wrote.

Gaia Vetere, MD, of the University of Exeter in Exeter, England, led the study, which was published online on January 28, 2024, in the International Journal of Geriatric Psychiatry.

LIMITATIONS:

The data were self-reported so may be subject to bias, and the size of the comparison group (those who didn’t play an instrument or sing) was much smaller.

DISCLOSURES:

The study was funded by the National Institute for Health and Care Research Exeter Biomedical Research Centre. Disclosures were noted in the original article.

• This was a nested study within PROTECT-UK, a longitudinal cohort study designed to examine aging and brain health. Participants completed three tests for working memory and one for executive function up to three times a year between 2019 and 2022.
• A group of 1107 participants (83% female; mean age 68 years) completed the Edinburgh Lifetime Musical Experience Questionnaire, which posed questions about playing musical instruments, singing, listening to music, and self-reported musical ability.
• Participants were split into two groups, namely, those who reported singing or playing a musical instrument (89%) or not (11%), and compared.

TAKEAWAY:

• Participants who reported playing a musical instrument performed significantly better on working memory (P < .0001) and executive function tasks (P < .0005) than those who didn’t play an instrument.
• The effect on working memory was the most heightened in those who reported playing keyboard (P < .0001), while those who played a woodwind instrument (P < .04) and/or sang (P < .014) showed significantly better performance on the executive function task.
• Nearly 90% of the sample had experience playing a musical instrument, with 44% playing currently. The majority of participants reported playing either one (28%) or two (23%) instruments.

IN PRACTICE:

Public health interventions might promote dementia risk reduction by incorporating music into programming, the authors concluded. “There is considerable evidence for the benefit of music group activities for individuals with dementia, and this approach could be extended as part of a health aging package for healthy older adults to enable them to proactively reduce their risk and to promote brain health,” they wrote.

The number of state psychiatric hospital beds has hit a historic low with about 11 beds per 100,000 population, a new report showed.

More than half of those beds (52%) were occupied by forensic patients, individuals with serious mental illness (SMI) who were committed to the state hospital through the criminal legal system to help establish competency for trial.

“The shortage of psychiatric beds has real consequences for people with SMI — some will wait months in jail despite not yet being found guilty of a crime, others will be denied admission despite being critically ill, and others still will be discharged prematurely onto the streets to free up beds, where they may grow sicker and be at an elevated risk of mortality,” wrote report coauthors Shanti Silver of the Treatment Advocacy Center (TAC) in Arlington and Elizabeth Sinclair Hanq of the National Association of State Mental Health Program Directors in Alexandria, Virginia.

Published online on January 24, Prevention Over Punishment: Finding the Right Balance of Civil and Forensic State Psychiatric Hospital Beds recommends that state and local governments work together to open additional state psychiatric hospital beds for civil and forensic patients with SMI.

To obtain data about the availability of state psychiatric hospital beds, TAC surveyed state officials from April to August 2023. Official responses were provided by 41 states and the District of Columbia.

Information for the remaining states was gathered from state websites, media articles, preexisting reports, hospital admission staff, or personal contacts living in those states.

The median occupancy rate for state-run hospitals in the new report was 90%, well above the 85% level investigators say usually signals a bed shortage. Overall, 73% of states reported occupancy rates above that level, with 11 states operating at 95% capacity.

The proportion of state psychiatric beds occupied by forensic patients has increased by 12% since 2016, largely driven by the growing number of individuals awaiting a competency determination to stand trial. Before they occupy these beds, however, people with SMI can languish in jail for months or even years, waiting for a bed to open.

About 15% of all state hospital beds and 31% of forensic beds across 34 states were occupied by individuals who had been found not guilty of a crime by reasons of insanity.

“The prioritization of admission of forensic patients has effectively created a system where someone must be arrested to access a state hospital bed,” report coauthor Lisa Dailey, TAC executive director, told this news organization. “But there are not enough beds for forensic patients either; thousands of inmates are waiting in jail on any given day for a bed to open up.”

There are several factors contributing to the scarcity of beds, including an existing hospital staffing shortage made worse by the COVID-19 pandemic and a lack of appropriate discharge facilities.

Report authors offered a number of recommendations to federal, state, and local officials to increase the availability of state-run psychiatric hospital beds, including infrastructure changes involving recruiting and retaining staff for state hospitals and funding new discharge or step-down facilities so that patients have a place to recover when they leave the hospital.

Policy changes could also help, the report noted. Policymakers should consider “dismiss and transfer” procedures to address the backlog of nearly 6000 people with SMI waiting for a state hospital bed to achieve competency to stand trial. With “dismiss and transfer,” criminal charges are dismissed or suspended while an application for civil commitment is filed in the probate court. Once a civil commitment order has been issued, the individual is released to an outpatient commitment program for treatment.

“States must strive for prevention over punishment,” the report concluded.

There was no study funding reported, nor were disclosures available.

Leading a healthy lifestyle, including regular exercise, eating fruits and vegetables, and minimal alcohol consumption, is associated with better cognitive function in older adults, new research showed.

The study, which combined longitudinal and cohort data with postmortem brain pathology reports, found that the association held even in those with Alzheimer’s disease (AD) pathology, suggesting that lifestyle factors may provide cognitive reserve and improve cognitive abilities in older age.

“While we must use caution in interpreting our findings, in part due to its cross-sectional design, these results support the role of lifestyle in providing cognitive reserve to maintain cognitive function in older adults despite the accumulation of common dementia-related brain pathologies,” Klodian Dhana, MD, of the Rush University Medical Center in Chicago, Illinois, and colleagues wrote.

The study was published online in JAMA Neurology.
 

Better Cognition

The study included 586 participants (71% female) who were followed from 1997 until 2022 as part of the Rush Memory and Aging Project longitudinal cohort study.

Investigators collected information on lifestyle and demographic factors at regular intervals, as well as information on diet, alcohol intake, and time spent participating in moderate or vigorous physical activity such as gardening, walking, calisthenics, biking, or swimming. Participants also received annual cognitive tests.

In later years, participants answered questions about whether they played card games or checkers, read, visited a museum, or did other cognitively stimulating activities.

Postmortem exams allowed the researchers to assess brain pathology (mean age at death, 91 years).

Participants were categorized as living a healthy lifestyle if they scored well in five categories: They exercised moderately or vigorously for 150 minutes per week, did not smoke, consumed one to two drinks per week, regularly played card games or did puzzles, and followed the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay diet.

For every one-point increase in the healthy lifestyle score, there were 0.120 fewer units of beta-amyloid load in the brain and a 0.22 standardized unit higher score in cognitive performance (P < .001).

After adjusting for the beta-amyloid load, phosphorated tau tangle, or other dementia-related brain pathologies, the healthy lifestyle score remained independently associated with cognition (P < .001).

More than 88% of a person’s global cognition score was a “direct association of lifestyle,” investigators noted, leaving slightly less than 12% affected by the presence of beta-amyloid.

“The mechanistic link between lifestyle and cognition could be attributed in part to the antioxidant and anti-inflammatory capacities of each lifestyle factor (eg, nutrition and physical activity) and cognitive reserve (eg, cognitive activities) that contribute to less inflammation and oxidative stress,” the authors wrote.

Further studies are necessary, they added, especially research investigating the association of lifestyle factors with markers for inflammation to understand the mechanisms of how lifestyle is associated with better cognitive scores in old age.

Study limitations include the reliance on self-reported data because cognitive impairment could interfere with inaccurate reporting. In addition, the authors noted that cognitive abilities may affect adherence to lifestyle factors.
 

‘Important Evidence’

In an accompanying editorial, Yue Leng, MD, and Kristine Yaffe, MD, of the University of San Francisco in San Francisco, California, noted that the new study adds “important evidence” to the debate over modifiable risk factors and reduction of AD risk.

“These interesting results add strength to the concept that health and lifestyle factors are important strategies for prevention and suggest that several mechanisms may be at work,” they wrote, adding that the study is “one of the first to harness brain pathology to investigate these mechanisms and is a crucial step forward in addressing these important questions.”

Still, critical questions remain regarding the mechanistic pathways linking modifiable risk factors and cognitive aging, Drs. Leng and Yaffe wrote.

“There is an urgent need for more well-designed randomized controlled trials to pave the way for dementia risk reduction in the era of precision medicine,” they wrote. “These strategies should be offered in conjunction with AD medications, similar to the approach in cardiovascular disease prevention and treatment in which medications along with lifestyle strategies are the standard of care.”

The study was funded by the National Institute on Aging. Dr. Dhana reported grants paid to his institution from the Alzheimer’s Association. No other disclosures were reported.

In patients with stimulant use disorder (SUD), even slight reductions in drug use can lessen depression and reduce cravings, a new analysis showed.

Abstinence has long been the overall goal of SUD treatment, the investigators noted. The findings from this pooled analysis of randomized clinical trials support what investigators noted was a growing recognition that reducing stimulant use can lead to better outcomes.

“This study provides evidence that reducing the overall use of drugs is important and clinically meaningful,” study author Mehdi Farokhnia, MD, MPH, of the National Institute on Drug Abuse, North Bethesda, Maryland, wrote in a press release. “This shift may open opportunities for medication development that can help individuals achieve these improved outcomes, even if complete abstinence is not immediately achievable or wanted.”

The findings were published online on January 10, 2024, in Addiction.
 

Not the Only Indicator of Success

To compare clinical indicators of improvement among those with SUDs who achieved abstinence or reduced their use, investigators pooled data from 13 randomized clinical trials with more than 2000 patients seeking treatment for cocaine or methamphetamine use disorders at centers in the United States from 2001 to 2017.

The trials used similar study protocols, including similar eligibility criteria, recruitment methods, and outcome measures. Participants were 18 or older and met criteria for methamphetamine or cocaine dependence at the beginning of each trial.

Among the participants, 1196 sought treatment for cocaine use disorder and 866 for methamphetamine use disorder. Of those, just 1487 had outcomes available by the end of the trial.

Most participants had no change in the level of use or increased their use through the trial (68%) or transitioned from low (1-4 days a month) to high (5 or more days a month) frequency use.

Nearly one third of participants (32%) stopped or reduced drug use, including 18% who cut down on stimulant use and 14% who abstained altogether.

Participants using methamphetamine were more likely to be in the abstinence vs reduced use category (21.3% vs 13.9%, respectively), whereas participants using cocaine were less likely to be in the abstinence vs reduced use category (9.1% vs 20.9%).

Those who reached abstinence showed better clinical improvement than those who reduced use on most clinical measures (P < .009).

However, there were no significant differences between groups on the Addiction Severity Index (ASI) psychiatric problems subscale and cravings for secondary drugs.

“Our findings suggest that reduced frequency of stimulant use is also associated with improved psychosocial functioning,” the authors wrote. “These findings suggest the need to re-evaluate the traditional approach of exclusively relying on total abstinence as the only indicator of successful treatment, a goal that may not be achievable for all patients, especially after one treatment episode.”

Those who reduced drug intake showed a significant association with nearly all clinical indicators of improvement (P < .010) compared with those who didn’t, except for the ASI psychiatric problems subscale and family/social relationship domains of the Problem Free Functioning scale, and HIV risk behavior.

Study limitations included short follow-up time in most trials and follow-up measures were based only on urine drug screens. There were also a substantial number of missing assessment points.

The study was funded by the National Institute on Drug Abuse and the National Institute of Health. There were no reported disclosures.

Study limitations included short follow-up time in most trials and follow-up measures were based only on urine drug screens. There were also a substantial number of missing assessment points.

The study was funded by the National Institute on Drug Abuse and the National Institute of Health. There were no reported disclosures.
