Too little sleep or poor sleep quality during the teen years can significantly increase the risk for multiple sclerosis (MS) during adulthood, new research suggests.

In a large case-control study, individuals who slept less than 7 hours a night on average during adolescence were 40% more likely to develop MS later on. The risk was even higher for those who rated their sleep quality as bad.

On the other hand, MS was significantly less common among individuals who slept longer as teens – indicating a possible protective benefit.

While sleep duration has been associated with mortality or disease risk for other conditions, sleep quality usually has little to no effect on risk, lead investigator Torbjörn Åkerstedt, PhD, sleep researcher and professor of psychology, department of neuroscience, Karolinska Institutet, Stockholm, told this news organization.

“I hadn’t really expected that, but those results were quite strong, even stronger than sleep duration,” Dr. Åkerstedt said.

“We don’t really know why this is happening in young age, but the most suitable explanation is that the brain in still developing quite a bit, and you’re interfering with it,” he added.

The findings were published online in the Journal of Neurology, Neurosurgery and Psychiatry.
 

Strong association

Other studies have tied sleep deprivation to increased risk for serious illness, but the link between sleep and MS risk isn’t as well studied.

Previous research by Dr. Åkerstedt showed that the risk for MS was higher among individuals who took part in shift work before the age of 20. However, the impact of sleep duration or quality among teens was unknown.

The current Swedish population-based case-control study included 2,075 patients with MS and 3,164 without the disorder. All participants were asked to recall how many hours on average they slept per night between the ages of 15 and 19 years and to rate their sleep quality during that time.

Results showed that individuals who slept fewer than 7 hours a night during their teen years were 40% more likely to have MS as adults (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.1-1.7).

Poor sleep quality increased MS risk even more (OR, 1.5; 95% CI, 1.3-1.9).

The association remained strong even after adjustment for additional sleep on weekends and breaks and excluding shift workers.
 

Long sleep ‘apparently good’

The researchers also conducted several sensitivity studies to rule out confounders that might bias the association, such as excluding participants who reported currently experiencing less sleep or poor sleep.

“You would expect that people who are suffering from sleep problems today would be the people who reported sleep problems during their youth,” but that didn’t happen, Dr. Åkerstedt noted.

The investigators also entered data on sleep duration and sleep quality at the same time, thinking the data would cancel each other out. However, the association remained the same.

“Quite often you see that sleep duration would eliminate the effect of sleep complaints in the prediction of disease, but here both remain significant when they are entered at the same time,” Dr. Åkerstedt said. “You get the feeling that this might mean they act together to produce results,” he added.

“One other thing that surprised me is that long sleep was apparently good,” said Dr. Åkerstedt.

The investigators have conducted several studies on sleep duration and mortality. In recent research, they found that both short sleep and long sleep predicted mortality – “and often, long sleep is a stronger predictor than short sleep,” he said.
 

Underestimated problem?

Commenting on the findings, Kathleen Zackowski, PhD, associate vice president of research for the National Multiple Sclerosis Society in Baltimore, noted that participants were asked to rate their own sleep quality during adolescence, a subjective report that may mean sleep quality has an even larger association with MS risk.

“That they found a result with sleep quality says to me that there probably is a bigger problem, because I don’t know if people over- or underestimate their sleep quality,” said Dr. Zackowski, who was not involved with the research.

“If we could get to that sleep quality question a little more objectively, I bet that we’d find there’s a lot more to the story,” she said.

That’s a story the researchers would like to explore, Dr. Åkerstedt reported. Designing a prospective study that more closely tracks sleeping habits during adolescence and follows individuals through adulthood could provide valuable information about how sleep quality and duration affect immune system development and MS risk, he said.

Dr. Zackowski said clinicians know that MS is not caused just by a genetic abnormality and that other environmental lifestyle factors seem to play a part.

“If we find out that sleep is one of those lifestyle factors, this is very changeable,” she added.

The study was funded by the Swedish Research Council, the Swedish Research Council for Health, Working Life and Welfare, the Swedish Brain Foundation, AFA Insurance, the European Aviation Safety Authority, the Tercentenary Fund of the Bank of Sweden, the Margaretha af Ugglas Foundation, the Swedish Foundation for MS Research, and NEURO Sweden. Dr. Åkerstadt has been supported by Tercentenary Fund of Bank of Sweden, AFA Insurance, and the European Aviation Safety Authority. Dr. Zackowski reports no relevant financial relationships.

A surgeon in Tulsa shot by a disgruntled patient. A doctor in India beaten by a group of bereaved family members. A general practitioner in the United Kingdom threatened with stabbing. The reality is grim: Health care workers across the globe experience violence while at work. A new study identifies this trend and finds that 25% of health care workers polled were willing to quit because of such violence.

“That was pretty appalling,” Rahul Kashyap, MD, MBA, MBBS, recalls. Dr. Kashyap is one of the leaders of the Violence Study of Healthcare Workers and Systems (ViSHWaS), which polled an international sample of physicians, nurses, and hospital staff. This study has worrying implications, Dr. Kashyap says. In a time when hospital staff are reporting burnout in record numbers, further deterrents may be the last thing our health care system needs. But Dr. Kashyap hopes that bringing awareness to these trends may allow physicians, policymakers, and the public to mobilize and intervene before it’s too late.

Previous studies have revealed similar trends. The rate of workplace violence directed at U.S. health care workers is five times that of workers in any other industry, according to the Bureau of Labor Statistics. The same study found that attacks had increased 63% from 2011 to 2018. Other polls that focus on the pandemic show that nearly half of U.S. nurses believe that violence increased since the world shut down. Well before the pandemic, however, a study from the Indian Medical Association found that 75% of doctors experienced workplace violence.

With this history in mind, perhaps it’s not surprising that the idea for the study came from the authors’ personal experiences. They had seen coworkers go through attacks, or they had endured attacks themselves, Dr. Kashyap says. But they couldn’t find any global data to back up these experiences. So Dr. Kashyap and his colleagues formed a web of volunteers dedicated to creating a cross-sectional study.

They got in touch with researchers from countries across Asia, the Middle East, South America, North America, and Africa. The initial group agreed to reach out to their contacts, casting a wide net. Researchers used WhatsApp, LinkedIn, and text messages to distribute the survey. Health care workers in each country completed the brief questionnaire, recalling their prepandemic world and evaluating their current one.

Within 2 months, they had reached health care workers in more than 100 countries. They concluded the study when they received about 5,000 results, according to Dr. Kashyap, and then began the process of stratifying the data. For this report, they focused on critical care, emergency medicine, and anesthesiology, which resulted in 598 responses from 69 countries. Of these, India and the United States had the highest number of participants.

In all, 73% of participants reported facing physical or verbal violence while in the hospital; 48% said they felt less motivated to work because of that violence; 39% of respondents believed that the amount of violence they experienced was the same as before the COVID-19 pandemic; and 36% of respondents believed that violence had increased. Even though they were trained on guidelines from the Occupational Safety and Health Administration, 20% of participants felt unprepared to face violence.

Although the study didn’t analyze the reasons workers felt this way, Dr. Kashyap speculates that it could be related to the medical distrust that grew during the pandemic or the stress patients and health care professionals experienced during its peak.

Regardless, the researchers say their study is a starting point. Now that the trend has been highlighted, it may be acted on.

Moving forward, Dr. Kashyap believes that controlling for different variables could determine whether factors like gender or shift time put a worker at higher risk for violence. He hopes it’s possible to interrupt these patterns and reestablish trust in the hospital environment. “It’s aspirational, but you’re hoping that through studies like ViSHWaS, which means trust in Hindi ... [we could restore] the trust and confidence among health care providers for the patients and family members.”

At least one state licensing agency is revoking nursing licenses allegedly obtained in a multistate fake diploma scheme.

The U.S. Department of Justice recently announced charges against 25 owners, operators, and employees of three Florida nursing schools in a fraud scheme in which they sold as many as 7,600 fake nursing degrees.

The purchasers in the diploma scheme paid $10,000 to $15,000 for degrees and transcripts and some 2,800 of the buyers passed the national nursing licensing exam to become registered nurses (RNs) and licensed practice nurses/vocational nurses (LPN/VNs) around the country, according to The New York Times.

Many of the degree recipients went on to work at hospitals, nursing homes, and Veterans Affairs medical centers, according to the U.S. Attorney’s Office for the Southern District of Florida.

Several national nursing organizations cooperated with the investigation, and the Delaware Division of Professional Regulation already annulled 26 licenses, according to the Delaware Nurses Association. Fake licenses were issued in five states, according to federal reports.

“We are deeply unsettled by this egregious act,” DNA President Stephanie McClellan, MSN, RN, CMSRN, said in the group’s press statement. “We want all Delaware nurses to be aware of this active issue and to speak up if there is a concern regarding capacity to practice safely by a colleague/peer,” she said.

The Oregon State Board of Nursing is also investigating at least a dozen nurses who may have paid for their degrees, according to a Portland CBS affiliate.

The National Council of State Boards of Nursing said in a statement that it had helped authorities identify and monitor the individuals who allegedly provided the false degrees.
 

Nursing community reacts

News of the fraud scheme spread through the nursing community, including social media. “The recent report on falsified nursing school degrees is both heartbreaking and serves as an eye-opener,” tweeted Usha Menon, PhD, RN, FAAN, dean and health professor of the University of South Florida Health College of Nursing. “There was enough of a need that prompted these bad actors to develop a scheme that could’ve endangered dozens of lives.”

Jennifer Mensik Kennedy, PhD, MBA, RN, the new president of the American Nurses Association, also weighed in. “The accusation that personnel at once-accredited nursing schools allegedly participated in this scheme is simply deplorable. These unlawful and unethical acts disparage the reputation of actual nurses everywhere who have rightfully earned [their titles] through their education, hard work, dedication, and time.”

The false degrees and transcripts were issued by three once-accredited and now-shuttered nursing schools in South Florida: Palm Beach School of Nursing, Sacred Heart International Institute, and Sienna College.

The alleged co-conspirators reportedly made $114 million from the scheme, which dates back to 2016, according to several news reports. Each defendant faces up to 20 years in prison.

Most LPN programs charge $10,000 to $15,000 to complete a program, Robert Rosseter, a spokesperson for the American Association of Colleges of Nursing (AACN), told this news organization.

None were AACN members, and none were accredited by the Commission on Collegiate Nursing Education, which is AACN’s autonomous accrediting agency, Mr. Rosseter said. AACN membership is voluntary and is open to schools offering baccalaureate or higher degrees, he explained.

“What is disturbing about this investigation is that there are over 7,600 people around the country with fraudulent nursing credentials who are potentially in critical health care roles treating patients,” Chad Yarbrough, acting special agent in charge for the FBI in Miami, said in the federal justice department release.
 

‘Operation Nightingale’ based on tip

The federal action, dubbed “Operation Nightingale” after the nursing pioneer Florence Nightingale, began in 2019. It was based on a tip related to a case in Maryland, according to Nurse.org.

That case ensnared Palm Beach School of Nursing owner Johanah Napoleon, who reportedly was selling fake degrees for $6,000 to $18,000 each to two individuals in Maryland and Virginia. Ms. Napoleon was charged in 2021 and eventually pled guilty. The Florida Board of Nursing shut down the Palm Beach school in 2017 owing to its students’ low passing rate on the national licensing exam.

Two participants in the bigger scheme who had also worked with Ms. Napoleon – Geralda Adrien and Woosvelt Predestin – were indicted in 2021. Ms. Adrien owned private education companies for people who at aspired to be nurses, and Mr. Predestin was an employee. They were sentenced to 27 months in prison last year and helped the federal officials build the larger case.

The 25 individuals who were charged Jan. 25 operated in Delaware, New York, New Jersey, Texas, and Florida.
 

Schemes lured immigrants

In the scheme involving Siena College, some of the individuals acted as recruiters to direct nurses who were looking for employment to the school, where they allegedly would then pay for an RN or LPN/VN degree. The recipients of the false documents then used them to obtain jobs, including at a hospital in Georgia and a Veterans Affairs medical center in Maryland, according to one indictment. The president of Siena and her co-conspirators sold more than 2,000 fake diplomas, according to charging documents.

At the Palm Beach College of Nursing, individuals at various nursing prep and education programs allegedly helped others obtain fake degrees and transcripts, which were then used to pass RN and LPN/VN licensing exams in states that included Massachusetts, New Jersey, New York, and Ohio, according to the indictment.

Some individuals then secured employment with a nursing home in Ohio, a home health agency for pediatric patients in Massachusetts, and skilled nursing facilities in New York and New Jersey.

Prosecutors allege that the president of Sacred Heart International Institute and two other co-conspirators sold 588 fake diplomas.

The FBI said that some of the aspiring nurses who were talked into buying the degrees were LPNs who wanted to become RNs and that most of those lured into the scheme were from South Florida’s Haitian American immigrant community, Nurse.org reported.

News of the fraud scheme spread through the nursing community, including social media. “The recent report on falsified nursing school degrees is both heartbreaking and serves as an eye-opener,” tweeted Usha Menon, PhD, RN, FAAN, dean and health professor of the University of South Florida Health College of Nursing. “There was enough of a need that prompted these bad actors to develop a scheme that could’ve endangered dozens of lives.”

Jennifer Mensik Kennedy, PhD, MBA, RN, the new president of the American Nurses Association, also weighed in. “The accusation that personnel at once-accredited nursing schools allegedly participated in this scheme is simply deplorable. These unlawful and unethical acts disparage the reputation of actual nurses everywhere who have rightfully earned [their titles] through their education, hard work, dedication, and time.”

The false degrees and transcripts were issued by three once-accredited and now-shuttered nursing schools in South Florida: Palm Beach School of Nursing, Sacred Heart International Institute, and Sienna College.

The alleged co-conspirators reportedly made $114 million from the scheme, which dates back to 2016, according to several news reports. Each defendant faces up to 20 years in prison.

Most LPN programs charge $10,000 to $15,000 to complete a program, Robert Rosseter, a spokesperson for the American Association of Colleges of Nursing (AACN), told this news organization.

None were AACN members, and none were accredited by the Commission on Collegiate Nursing Education, which is AACN’s autonomous accrediting agency, Mr. Rosseter said. AACN membership is voluntary and is open to schools offering baccalaureate or higher degrees, he explained.

“What is disturbing about this investigation is that there are over 7,600 people around the country with fraudulent nursing credentials who are potentially in critical health care roles treating patients,” Chad Yarbrough, acting special agent in charge for the FBI in Miami, said in the federal justice department release.
 

‘Operation Nightingale’ based on tip

The federal action, dubbed “Operation Nightingale” after the nursing pioneer Florence Nightingale, began in 2019. It was based on a tip related to a case in Maryland, according to Nurse.org.

That case ensnared Palm Beach School of Nursing owner Johanah Napoleon, who reportedly was selling fake degrees for $6,000 to $18,000 each to two individuals in Maryland and Virginia. Ms. Napoleon was charged in 2021 and eventually pled guilty. The Florida Board of Nursing shut down the Palm Beach school in 2017 owing to its students’ low passing rate on the national licensing exam.

Two participants in the bigger scheme who had also worked with Ms. Napoleon – Geralda Adrien and Woosvelt Predestin – were indicted in 2021. Ms. Adrien owned private education companies for people who at aspired to be nurses, and Mr. Predestin was an employee. They were sentenced to 27 months in prison last year and helped the federal officials build the larger case.

The 25 individuals who were charged Jan. 25 operated in Delaware, New York, New Jersey, Texas, and Florida.
 

Schemes lured immigrants

In the scheme involving Siena College, some of the individuals acted as recruiters to direct nurses who were looking for employment to the school, where they allegedly would then pay for an RN or LPN/VN degree. The recipients of the false documents then used them to obtain jobs, including at a hospital in Georgia and a Veterans Affairs medical center in Maryland, according to one indictment. The president of Siena and her co-conspirators sold more than 2,000 fake diplomas, according to charging documents.

At the Palm Beach College of Nursing, individuals at various nursing prep and education programs allegedly helped others obtain fake degrees and transcripts, which were then used to pass RN and LPN/VN licensing exams in states that included Massachusetts, New Jersey, New York, and Ohio, according to the indictment.

Some individuals then secured employment with a nursing home in Ohio, a home health agency for pediatric patients in Massachusetts, and skilled nursing facilities in New York and New Jersey.

Prosecutors allege that the president of Sacred Heart International Institute and two other co-conspirators sold 588 fake diplomas.

The FBI said that some of the aspiring nurses who were talked into buying the degrees were LPNs who wanted to become RNs and that most of those lured into the scheme were from South Florida’s Haitian American immigrant community, Nurse.org reported.

At least one state licensing agency is revoking nursing licenses allegedly obtained in a multistate fake diploma scheme.

The U.S. Department of Justice recently announced charges against 25 owners, operators, and employees of three Florida nursing schools in a fraud scheme in which they sold as many as 7,600 fake nursing degrees.

The purchasers in the diploma scheme paid $10,000 to $15,000 for degrees and transcripts and some 2,800 of the buyers passed the national nursing licensing exam to become registered nurses (RNs) and licensed practice nurses/vocational nurses (LPN/VNs) around the country, according to The New York Times.

Many of the degree recipients went on to work at hospitals, nursing homes, and Veterans Affairs medical centers, according to the U.S. Attorney’s Office for the Southern District of Florida.

Several national nursing organizations cooperated with the investigation, and the Delaware Division of Professional Regulation already annulled 26 licenses, according to the Delaware Nurses Association. Fake licenses were issued in five states, according to federal reports.

“We are deeply unsettled by this egregious act,” DNA President Stephanie McClellan, MSN, RN, CMSRN, said in the group’s press statement. “We want all Delaware nurses to be aware of this active issue and to speak up if there is a concern regarding capacity to practice safely by a colleague/peer,” she said.

The Oregon State Board of Nursing is also investigating at least a dozen nurses who may have paid for their degrees, according to a Portland CBS affiliate.

The National Council of State Boards of Nursing said in a statement that it had helped authorities identify and monitor the individuals who allegedly provided the false degrees.

The two national emergency declarations dealing with the COVID-19 pandemic will end May 11, President Joe Biden said on Jan. 30.

Doing so will have many effects, including the end of free vaccines and health services to fight the pandemic. The public health emergency has been renewed every 90 days since it was declared by the Trump administration in January 2020.

The declaration allowed major changes throughout the health care system to deal with the pandemic, including the free distribution of vaccines, testing, and treatments. In addition, telehealth services were expanded, and Medicaid and the Children’s Health Insurance Program were extended to millions more Americans.

Biden said the COVID-19 national emergency is set to expire March 1 while the declared public health emergency would currently expire on April 11. The president said both will be extended to end May 11.

There were nearly 300,000 newly reported COVID-19 cases in the United States for the week ending Jan. 25, according to CDC data, as well as more than 3,750 deaths.

Hidden in the Dec. 1, 2022, issue of the New England Journal of Medicine was a small article on using deferiprone for Parkinson’s disease.

The idea behind it makes sense. A key factor in Parkinson’s disease is a loss of cells in the substantia nigra. The cells that have been lost have a build-up of iron content, suggesting that iron contributes to their demise. Therefore, maybe using an iron chelating agent to remove it may help.

Like I said, it makes sense.

Unfortunately, it didn’t quite work that way. In spite of a clear reduction of nigrostriatal iron, compared with the placebo group, the treated patients had worse MDS-UPDRS scores over 36 weeks than those on the placebo.

Back to the drawing board.

I’m not criticizing the people who did the study – it seemed like a reasonable hypothesis, and testing it is the only way we find out if it’s correct. We learn just as much, if not more, from a negative study as from a positive one, incrementally working toward the answer with each.

We face the same thing with the amyloid theory in Alzheimer’s disease. Getting rid of amyloid should fix the problem.

But it doesn’t, at least not completely. Even lecanemab, the latest-and-greatest of treatments, only shows a 27% slowing in disease progression. This is certainly meaningful – I’m not knocking it – but we’re still far from a cure. To date we haven’t even stopped disease progression, let alone reversed it.

Although the new drugs have a remarkable mechanism of action, the clinical results aren’t nearly as good as one would expect if amyloid was the whole issue.

Which, at this point, it probably isn’t, anymore than nigrostriatal iron deposition is the sole cause of Parkinson’s disease.

In medicine, as in so many other things, there’s simply a lot that we don’t know yet. Right now we’re better able to find planets 27,700 light years away (SWEEPS-11) than we are at knowing the cause of neuronal changes in the person sitting across the desk from us. That’s not saying we won’t have the answers someday, it just means we don’t have them now.

I was in my 3rd year of medical school in January of 1992, (surgery rotation at the Omaha VA, to be specific) when the first definitive planet outside our solar system was identified. Today, 31 years later, the number of exoplanets stands at 5,297.

But the laws of physics are generally a lot more predictable than those of biology.

That doesn’t mean we won’t find the answers, or more effective treatments, eventually. But it will take more time, work, and studies – with both positive and negative results – to get there.

Adhering to six healthy lifestyle behaviors is linked to slower memory decline in older adults, a large population-based study suggests.

Investigators found that a healthy diet, cognitive activity, regular physical exercise, not smoking, and abstaining from alcohol were significantly linked to slowed cognitive decline irrespective of APOE4 status.

After adjusting for health and socioeconomic factors, investigators found that each individual healthy behavior was associated with a slower-than-average decline in memory over a decade. A healthy diet emerged as the strongest deterrent, followed by cognitive activity and physical exercise.

“A healthy lifestyle is associated with slower memory decline, even in the presence of the APOE4 allele,” study investigators led by Jianping Jia, MD, PhD, of the Innovation Center for Neurological Disorders and the department of neurology, Xuan Wu Hospital, Capital Medical University, Beijing, write.

“This study might offer important information to protect older adults against memory decline,” they add.

The study was published online in the BMJ.
 

Preventing memory decline

Memory “continuously declines as people age,” but age-related memory decline is not necessarily a prodrome of dementia and can “merely be senescent forgetfulness,” the investigators note. This can be “reversed or [can] become stable,” instead of progressing to a pathologic state.

Factors affecting memory include aging, APOE4 genotype, chronic diseases, and lifestyle patterns, with lifestyle “receiving increasing attention as a modifiable behavior.”

Nevertheless, few studies have focused on the impact of lifestyle on memory, and those that have are mostly cross-sectional and also “did not consider the interaction between a healthy lifestyle and genetic risk,” the researchers note.

To investigate, the researchers conducted a longitudinal study, known as the China Cognition and Aging Study, that considered genetic risk as well as lifestyle factors.

The study began in 2009 and concluded in 2019. Participants were evaluated and underwent neuropsychological testing in 2012, 2014, 2016, and at the study’s conclusion.

Participants (n = 29,072; mean [SD] age, 72.23 [6.61] years; 48.54% women; 20.43% APOE4 carriers) were required to have normal cognitive function at baseline. Data on those whose condition progressed to mild cognitive impairment (MCI) or dementia during the follow-up period were excluded after their diagnosis.

The Mini–Mental State Examination was used to assess global cognitive function. Memory function was assessed using the World Health Organization/University of California, Los Angeles Auditory Verbal Learning Test.

“Lifestyle” consisted of six modifiable factors: physical exercise (weekly frequency and total time), smoking (current, former, or never-smokers), alcohol consumption (never drank, drank occasionally, low to excess drinking, and heavy drinking), diet (daily intake of 12 food items: fruits, vegetables, fish, meat, dairy products, salt, oil, eggs, cereals, legumes, nuts, tea), cognitive activity (writing, reading, playing cards, mahjong, other games), and social contact (participating in meetings, attending parties, visiting friends/relatives, traveling, chatting online).

Participants’ lifestyles were scored on the basis of the number of healthy factors they engaged in.

Important for public health

During the 10-year period, 7,164 participants died, and 3,567 stopped participating.

Participants in the favorable and average groups showed slower memory decline per increased year of age (0.007 [0.005-0.009], P < .001; and 0.002 [0 .000-0.003], P = .033 points higher, respectively), compared with those in the unfavorable group.

Healthy diet had the strongest protective effect on memory.

‘Important, encouraging’ research

In a comment, Severine Sabia, PhD, a senior researcher at the Université Paris Cité, INSERM Institut National de la Santé et de la Recherche Medicalé, France, called the findings “important and encouraging.”

However, said Dr. Sabia, who was not involved with the study, “there remain important research questions that need to be investigated in order to identify key behaviors: which combination, the cutoff of risk, and when to intervene.”

Future research on prevention “should examine a wider range of possible risk factors” and should also “identify specific exposures associated with the greatest risk, while also considering the risk threshold and age at exposure for each one.”

In an accompanying editorial, Dr. Sabia and co-author Archana Singh-Manoux, PhD, note that the risk of cognitive decline and dementia are probably determined by multiple factors.

They liken it to the “multifactorial risk paradigm introduced by the Framingham study,” which has “led to a substantial reduction in cardiovascular disease.” A similar approach could be used with dementia prevention, they suggest.

The authors received support from the Xuanwu Hospital of Capital Medical University for the submitted work. One of the authors received a grant from the French National Research Agency. The other authors have disclosed no relevant financial relationships. Dr. Sabia received grant funding from the French National Research Agency. Dr. Singh-Manoux received grants from the National Institute on Aging of the National Institutes of Health.

“Lifestyle” consisted of six modifiable factors: physical exercise (weekly frequency and total time), smoking (current, former, or never-smokers), alcohol consumption (never drank, drank occasionally, low to excess drinking, and heavy drinking), diet (daily intake of 12 food items: fruits, vegetables, fish, meat, dairy products, salt, oil, eggs, cereals, legumes, nuts, tea), cognitive activity (writing, reading, playing cards, mahjong, other games), and social contact (participating in meetings, attending parties, visiting friends/relatives, traveling, chatting online).

Participants’ lifestyles were scored on the basis of the number of healthy factors they engaged in.

Important for public health

During the 10-year period, 7,164 participants died, and 3,567 stopped participating.

Participants in the favorable and average groups showed slower memory decline per increased year of age (0.007 [0.005-0.009], P < .001; and 0.002 [0 .000-0.003], P = .033 points higher, respectively), compared with those in the unfavorable group.

Healthy diet had the strongest protective effect on memory.

‘Important, encouraging’ research

In a comment, Severine Sabia, PhD, a senior researcher at the Université Paris Cité, INSERM Institut National de la Santé et de la Recherche Medicalé, France, called the findings “important and encouraging.”

However, said Dr. Sabia, who was not involved with the study, “there remain important research questions that need to be investigated in order to identify key behaviors: which combination, the cutoff of risk, and when to intervene.”

Future research on prevention “should examine a wider range of possible risk factors” and should also “identify specific exposures associated with the greatest risk, while also considering the risk threshold and age at exposure for each one.”

In an accompanying editorial, Dr. Sabia and co-author Archana Singh-Manoux, PhD, note that the risk of cognitive decline and dementia are probably determined by multiple factors.

They liken it to the “multifactorial risk paradigm introduced by the Framingham study,” which has “led to a substantial reduction in cardiovascular disease.” A similar approach could be used with dementia prevention, they suggest.

The authors received support from the Xuanwu Hospital of Capital Medical University for the submitted work. One of the authors received a grant from the French National Research Agency. The other authors have disclosed no relevant financial relationships. Dr. Sabia received grant funding from the French National Research Agency. Dr. Singh-Manoux received grants from the National Institute on Aging of the National Institutes of Health.

Sustaining even a single head injury has been linked to a significantly increased risk of all-cause mortality in new research.

An analysis of more than 13,000 adult participants in the Atherosclerosis Risk in Communities (ARIC) study showed a dose-response pattern in which one head injury was linked to a 66% increased risk for all-cause mortality, and two or more head injuries were associated with twice the risk in comparison with no head injuries.

These findings underscore the importance of preventing head injuries and of swift clinical intervention once a head injury occurs, lead author Holly Elser, MD, PhD, department of neurology, Hospital of the University of Pennsylvania, Philadelphia, told this news organization.

“Clinicians should counsel patients who are at risk for falls about head injuries and ensure patients are promptly evaluated in the hospital setting if they do have a fall – especially with loss of consciousness or other symptoms, such as headache or dizziness,” Dr. Elser added.

The findings were published online in JAMA Neurology.
 

Consistent evidence

There is “pretty consistent evidence” that mortality rates are increased in the short term after head injury, predominantly among hospitalized patients, Dr. Elser noted.

“But there’s less evidence about the long-term mortality implications of head injuries and less evidence from adults living in the community,” she added.

The analysis included 13,037 participants in the ARIC study, an ongoing study involving adults aged 45-65 years who were recruited from four geographically and racially diverse U.S. communities. The mean age at baseline (1987-1989) was 54 years; 57.7% were women; and 27.9% were Black.

Study participants are followed at routine in-person visits and semiannually via telephone.

Data on head injuries came from hospital diagnostic codes and self-reports. These reports included information on the number of injuries and whether the injury required medical care and involved loss of consciousness.

During the 27-year follow-up, 18.4% of the study sample had at least one head injury. Injuries occurred more frequently among women, which may reflect the predominance of women in the study population, said Dr. Elser.

Overall, about 56% of participants died during the study period. The estimated median amount of survival time after head injury was 4.7 years.

The most common causes of death were neoplasm, cardiovascular disease, and neurologic disorders. Regarding specific neurologic causes of death, the researchers found that 62.2% of deaths were due to neurodegenerative disease among individuals with head injury, vs. 51.4% among those without head injury.

This, said Dr. Elser, raises the possibility of reverse causality. “If you have a neurodegenerative disorder like Alzheimer’s disease dementia or Parkinson’s disease that leads to difficulty walking, you may be more likely to fall and have a head injury. The head injury in turn may lead to increased mortality,” she noted.

However, she stressed that the data on cause-specific mortality are exploratory. “Our research motivates future studies that really examine this time-dependent relationship between neurodegenerative disease and head injuries,” Dr. Elser said.
 

Dose-dependent response

In the unadjusted analysis, the hazard ratio of mortality among individuals with head injury was 2.21 (95% confidence interval, 2.09-2.34) compared with those who did not have head injury.

The association remained significant with adjustment for sociodemographic factors (HR, 1.99; 95% CI, 1.88-2.11) and with additional adjustment for vascular risk factors (HR, 1.92; 95% CI, 1.81-2.03).

The findings also showed a dose-response pattern in the association of head injuries with mortality. Compared with participants who did not have head injury, the HR was 1.66 (95% CI, 1.56-1.77) for those with one head injury and 2.11 (95% CI, 1.89-2.37) for those with two or more head injuries.

“It’s not as though once you’ve had one head injury, you’ve accrued all the damage you possibly can. We see pretty clearly here that recurrent head injury further increased the rate of deaths from all causes,” said Dr. Elser.

Injury severity was determined from hospital diagnostic codes using established algorithms. Results showed that mortality rates were increased with even mild head injury.

Interestingly, the association between head injury and all-cause mortality was weaker among those whose injuries were self-reported. One possibility is that these injuries were less severe, Dr. Elser noted.

“If you have head injury that’s mild enough that you don’t need to go to the hospital, it’s probably going to confer less long-term health risks than one that’s severe enough that you needed to be examined in an acute care setting,” she said.

Results were similar by race and for sex. “Even though there were more women with head injuries, the rate of mortality associated with head injury doesn’t differ from the rate among men,” Dr. Elser reported.

However, the association was stronger among those younger than 54 years at baseline (HR, 2.26) compared with older individuals (HR, 2.0) in the model that adjusted for demographics and lifestyle factors.

This may be explained by the reference group (those without a head injury) – the mortality rate was in general higher for the older participants, said Dr. Elser. It could also be that younger adults are more likely to have severe head injuries from, for example, motor vehicle accidents or violence, she added.

These new findings underscore the importance of public health measures, such as seatbelt laws, to reduce head injuries, the investigators note.

They add that clinicians with patients at risk for head injuries may recommend steps to lessen the risk of falls, such as having access to durable medical equipment, and ensuring driver safety.
 

Shorter life span

Commenting for this news organization, Frank Conidi, MD, director of the Florida Center for Headache and Sports Neurology in Port St. Lucie and past president of the Florida Society of Neurology, said the large number of participants “adds validity” to the finding that individuals with head injury are likely to have a shorter life span than those who do not suffer head trauma – and that this “was not purely by chance or from other causes.”

However, patients may not have accurately reported head injuries, in which case the rate of injury in the self-report subgroup would not reflect the actual incidence, noted Dr. Conidi, who was not involved with the research.

“In my practice, most patients have little knowledge as to the signs and symptoms of concussion and traumatic brain injury. Most think there needs to be some form of loss of consciousness to have a head injury, which is of course not true,” he said.

Dr. Conidi added that the finding of a higher incidence of death from neurodegenerative disorders supports the generally accepted consensus view that about 30% of patients with traumatic brain injury experience progression of symptoms and are at risk for early dementia.

The ARIC study is supported by the National Heart, Lung, and Blood Institute. Dr. Elser and Dr. Conidi have reported no relevant financial relationships.

When you became a doctor, you may have moved to one city for med school, another for residency, and a third to be an attending. All that moving can make it hard to maintain friendships. Factor in the challenges from the pandemic, and a physician’s life can be lonely. So, when a patient invites you for coffee or a game of pickleball, do you accept? For almost one-third of the physicians who responded to the Medscape Physician Friendships: The Joys and Challenges 2022, the answer might be yes.

About 29% said they develop friendships with patients. However, a lot depends on the circumstances. As one physician in the report said: “I have been a pediatrician for 35 years, and my patients have grown up and become productive adults in our small, rural, isolated area. You can’t help but know almost everyone.”

As the daughter of a cardiologist, Nishi Mehta, MD, a radiologist and founder of the largest physician-only Facebook group in the country, grew up with that small-town-everyone-knows-the-doctor model.

“When I was a kid, I’d go to the mall, and my friends and I would play a game: How long before a patient [of my dad’s] comes up to me?” she said. At the time, Dr. Mehta was embarrassed, but now she marvels that her dad knew his patients so well that they would recognize his daughter in crowded suburban mall.

In other instances, a physician may develop a friendly relationship after a patient leaves their care. For example, Leo Nissola, MD, now a full-time researcher and immunotherapy scientist in San Francisco, has stayed in touch with some of the patients he treated while at the University of Texas MD Anderson Cancer Center, Houston.

Dr. Nissola said it was important to stay connected with the patients he had meaningful relationships with. “It becomes challenging, though, when a former patient asks for medical advice.” At that moment, “you have to be explicitly clear that the relationship has changed.”
 

A hard line in the sand

The blurring of lines is one reason many doctors refuse to befriend patients, even after they are no longer treating them. The American College of Physicians Ethics Manual advises against treating anyone with whom you have a close relationship, including family and friends.

“Friendships can get in the way of patients being honest with you, which can interfere with medical care,” Dr. Mehta said. “If a patient has a concern related to something they wouldn’t want you to know as friends, it can get awkward. They may elect not to tell you.”

And on the flip side, friendship can provide a view into your private life that you may not welcome in the exam room.

“Let’s say you go out for drinks [with a patient], and you’re up late, but you have surgery the next day,” said Brandi Ring, MD, an ob.gyn. and the associate medical director at the Center for Children and Women in Houston. Now, one of your patients knows you were out until midnight when you had to be in the OR at 5:00 a.m.

Worse still, your relationship could color your decisions about a patient’s care, even unconsciously. It can be hard to maintain objectivity when you have an emotional investment in someone’s well-being.

“We don’t necessarily treat family and friends to the standards of medical care,” said Dr. Ring. “We go above and beyond. We might order more tests and more scans. We don’t always follow the guidelines, especially in critical illness.”

For all these reasons and more, the ACP advises against treating friends.
 

Put physician before friend

But adhering to those guidelines can lead physicians to make some painful decisions. Cutting yourself off from the possibility of friendship is never easy, and the Medscape report found that physicians tend to have fewer friends than the average American.

“Especially earlier in my practice, when I was a young parent, and I would see a lot of other young parents in the same stage in life, I’d think, ‘In other circumstances, I would be hanging out at the park with this person,’ “ said Kathleen Rowland, MD, a family medicine physician and vice chair of education in the department of family medicine at Rush University, Chicago. “But the hard part is, the doctor-patient relationship always comes first.”

To a certain extent, one’s specialty may determine the feasibility of becoming friends with a patient. While Dr. Mehta has never done so, as a radiologist, she doesn’t usually see patients repeatedly. Likewise, a young gerontologist may have little in common with his octogenarian patients. And an older pediatrician is not in the same life stage as his patients’ sleep-deprived new parents, possibly making them less attractive friends.

However, practicing family medicine is all about long-term physician-patient relationships. Getting to know patients and their families over many years can lead to a certain intimacy. Dr. Rowland said that, while a wonderful part of being a physician is getting that unique trust whereby patients tell you all sorts of things about their lives, she’s never gone down the friendship path.

“There’s the assumption I’ll take care of someone for a long period of time, and their partner and their kids, maybe another generation or two,” Dr. Rowland said. “People really do rely on that relationship to contribute to their health.”

Worse, nowadays, when people may be starved for connection, many patients want to feel emotionally close and cared for by their doctor, so it’d be easy to cross the line. While patients deserve a compassionate, caring doctor, the physician is left to walk the line between those boundaries. Dr. Rowland said, “It’s up to the clinician to say: ‘My role is as a doctor. You deserve caring friends, but I have to order your mammogram and your blood counts. My role is different.’ ”
 

Friendly but not friends

It can be tricky to navigate the boundary between a cordial, warm relationship with a patient and that patient inviting you to their daughter’s wedding.

“People may mistake being pleasant and friendly for being friends,” said Larry Blosser, MD, chief medical officer at Central Ohio Primary Care, Westerville. In his position, he sometimes hears from patients who have misunderstood their relationship with a doctor in the practice. When that happens, he advises the physician to consider the persona they’re presenting to the patient. If you’re overly friendly, there’s the potential for confusion, but you can’t be aloof and cold, he said.

Maintaining that awareness helps to prevent a patient’s offhand invitation to catch a movie or go on a hike. And verbalizing it to your patients can make your relationship clear from the get-go.

“I tell patients we’re a team. I’m the captain, and they’re my MVP. When the match is over, whatever the results, we’re done,” said Karenne Fru, MD, PhD, a fertility specialist at Oma Fertility Atlanta. Making deep connections is essential to her practice, so Dr. Fru structures her patient interactions carefully. “Infertility is such an isolating experience. While you’re with us, we care about what’s going on in your life, your pets, and your mom’s chemo. We need mutual trust for you to be compliant with the care.”

However, that approach won’t work when you see patients regularly, as with family practice or specialties that see the same patients repeatedly throughout the year. In those circumstances, the match is never over but one in which the onus is on the physician to establish a friendly yet professional rapport without letting your self-interest, loneliness, or lack of friends interfere.

“It’s been a very difficult couple of years for a lot of us. Depending on what kind of clinical work we do, some of us took care of healthy people that got very sick or passed away,” Dr. Rowland said. “Having the chance to reconnect with people and reestablish some of that closeness, both physical and emotional, is going to be good for us.”

Just continue conveying warm, trusting compassion for your patients without blurring the friend lines.

For all these reasons and more, the ACP advises against treating friends.
 

Put physician before friend

But adhering to those guidelines can lead physicians to make some painful decisions. Cutting yourself off from the possibility of friendship is never easy, and the Medscape report found that physicians tend to have fewer friends than the average American.

“Especially earlier in my practice, when I was a young parent, and I would see a lot of other young parents in the same stage in life, I’d think, ‘In other circumstances, I would be hanging out at the park with this person,’ “ said Kathleen Rowland, MD, a family medicine physician and vice chair of education in the department of family medicine at Rush University, Chicago. “But the hard part is, the doctor-patient relationship always comes first.”

To a certain extent, one’s specialty may determine the feasibility of becoming friends with a patient. While Dr. Mehta has never done so, as a radiologist, she doesn’t usually see patients repeatedly. Likewise, a young gerontologist may have little in common with his octogenarian patients. And an older pediatrician is not in the same life stage as his patients’ sleep-deprived new parents, possibly making them less attractive friends.

However, practicing family medicine is all about long-term physician-patient relationships. Getting to know patients and their families over many years can lead to a certain intimacy. Dr. Rowland said that, while a wonderful part of being a physician is getting that unique trust whereby patients tell you all sorts of things about their lives, she’s never gone down the friendship path.

“There’s the assumption I’ll take care of someone for a long period of time, and their partner and their kids, maybe another generation or two,” Dr. Rowland said. “People really do rely on that relationship to contribute to their health.”

Worse, nowadays, when people may be starved for connection, many patients want to feel emotionally close and cared for by their doctor, so it’d be easy to cross the line. While patients deserve a compassionate, caring doctor, the physician is left to walk the line between those boundaries. Dr. Rowland said, “It’s up to the clinician to say: ‘My role is as a doctor. You deserve caring friends, but I have to order your mammogram and your blood counts. My role is different.’ ”
 

Friendly but not friends

It can be tricky to navigate the boundary between a cordial, warm relationship with a patient and that patient inviting you to their daughter’s wedding.

“People may mistake being pleasant and friendly for being friends,” said Larry Blosser, MD, chief medical officer at Central Ohio Primary Care, Westerville. In his position, he sometimes hears from patients who have misunderstood their relationship with a doctor in the practice. When that happens, he advises the physician to consider the persona they’re presenting to the patient. If you’re overly friendly, there’s the potential for confusion, but you can’t be aloof and cold, he said.

Maintaining that awareness helps to prevent a patient’s offhand invitation to catch a movie or go on a hike. And verbalizing it to your patients can make your relationship clear from the get-go.

“I tell patients we’re a team. I’m the captain, and they’re my MVP. When the match is over, whatever the results, we’re done,” said Karenne Fru, MD, PhD, a fertility specialist at Oma Fertility Atlanta. Making deep connections is essential to her practice, so Dr. Fru structures her patient interactions carefully. “Infertility is such an isolating experience. While you’re with us, we care about what’s going on in your life, your pets, and your mom’s chemo. We need mutual trust for you to be compliant with the care.”

However, that approach won’t work when you see patients regularly, as with family practice or specialties that see the same patients repeatedly throughout the year. In those circumstances, the match is never over but one in which the onus is on the physician to establish a friendly yet professional rapport without letting your self-interest, loneliness, or lack of friends interfere.

“It’s been a very difficult couple of years for a lot of us. Depending on what kind of clinical work we do, some of us took care of healthy people that got very sick or passed away,” Dr. Rowland said. “Having the chance to reconnect with people and reestablish some of that closeness, both physical and emotional, is going to be good for us.”

Just continue conveying warm, trusting compassion for your patients without blurring the friend lines.

When you became a doctor, you may have moved to one city for med school, another for residency, and a third to be an attending. All that moving can make it hard to maintain friendships. Factor in the challenges from the pandemic, and a physician’s life can be lonely. So, when a patient invites you for coffee or a game of pickleball, do you accept? For almost one-third of the physicians who responded to the Medscape Physician Friendships: The Joys and Challenges 2022, the answer might be yes.

About 29% said they develop friendships with patients. However, a lot depends on the circumstances. As one physician in the report said: “I have been a pediatrician for 35 years, and my patients have grown up and become productive adults in our small, rural, isolated area. You can’t help but know almost everyone.”

As the daughter of a cardiologist, Nishi Mehta, MD, a radiologist and founder of the largest physician-only Facebook group in the country, grew up with that small-town-everyone-knows-the-doctor model.

“When I was a kid, I’d go to the mall, and my friends and I would play a game: How long before a patient [of my dad’s] comes up to me?” she said. At the time, Dr. Mehta was embarrassed, but now she marvels that her dad knew his patients so well that they would recognize his daughter in crowded suburban mall.

In other instances, a physician may develop a friendly relationship after a patient leaves their care. For example, Leo Nissola, MD, now a full-time researcher and immunotherapy scientist in San Francisco, has stayed in touch with some of the patients he treated while at the University of Texas MD Anderson Cancer Center, Houston.

Dr. Nissola said it was important to stay connected with the patients he had meaningful relationships with. “It becomes challenging, though, when a former patient asks for medical advice.” At that moment, “you have to be explicitly clear that the relationship has changed.”
 

A hard line in the sand

The blurring of lines is one reason many doctors refuse to befriend patients, even after they are no longer treating them. The American College of Physicians Ethics Manual advises against treating anyone with whom you have a close relationship, including family and friends.

“Friendships can get in the way of patients being honest with you, which can interfere with medical care,” Dr. Mehta said. “If a patient has a concern related to something they wouldn’t want you to know as friends, it can get awkward. They may elect not to tell you.”

And on the flip side, friendship can provide a view into your private life that you may not welcome in the exam room.

“Let’s say you go out for drinks [with a patient], and you’re up late, but you have surgery the next day,” said Brandi Ring, MD, an ob.gyn. and the associate medical director at the Center for Children and Women in Houston. Now, one of your patients knows you were out until midnight when you had to be in the OR at 5:00 a.m.

Worse still, your relationship could color your decisions about a patient’s care, even unconsciously. It can be hard to maintain objectivity when you have an emotional investment in someone’s well-being.

“We don’t necessarily treat family and friends to the standards of medical care,” said Dr. Ring. “We go above and beyond. We might order more tests and more scans. We don’t always follow the guidelines, especially in critical illness.”

General pediatricians and a multidisciplinary team of specialists agreed most of the time on which children should be diagnosed with autism spectrum disorder (ASD), data from a new study suggest.

But when it came to ruling out ASD, the agreement rate was much lower.

The study by Melanie Penner, MSc, MD, with the Autism Research Centre at Bloorview Research Institute, Toronto, and colleagues found that 89% of the time when a physician determined a child had ASD, the multidisciplinary team agreed. But when a pediatrician thought a child did not have ASD, the multidisciplinary team agreed only 60% of the time. The study was published in JAMA Network Open.

Multidisciplinary team model can’t keep up with demand

The findings are important as many guidelines recommend multidisciplinary teams (MDTs) for all ASD diagnostic assessment. However, the resources for this model can’t meet the demand of children needing a diagnosis and can lead to long waits for ASD therapies.

In Canada, the researchers note, the average wait time from referral to receipt of ASD diagnosis has been reported as 7 months and “has likely lengthened since the COVID-19 pandemic.”

Jennifer Gerdts, PhD, an attending psychologist at the Seattle Children’s Autism Center, said in an interview that the wait there for diagnosis in children older than 4 is “multiple years,” a length of time that’s common across the United States. Meanwhile, in many states families can’t access services without a diagnosis.

Expanding capacity with diagnoses by general pediatricians may improve access, but the diagnostic accuracy is critical.

Dr. Gerdts, who was not part of the study, said this research is “hugely important in the work that is under way to build community capacity for diagnostic evaluation.”

She said this study shows that not all diagnoses need the resources of a multiple-disciplinary team and that “pediatricians can do it, too, and they can do it pretty accurately.” Dr. Gerdts evaluates children for autism and helps train pediatricians to make diagnoses.
 

Pediatricians, specialist team completed blinded assessments

The 17 pediatricians in the study and the specialist team independently completed blinded assessment and each recorded a decision on whether the child had ASD. The prospective diagnostic study was conducted in a specialist assessment center in Toronto and in general pediatrician practices in Ontario from June 2016 to March 2020.

Children were younger than 5.5 years, did not have an ASD diagnosis and were referred because there was a development concern. The pediatricians referred 106 children (75% boys; average age, 3.5 years). More than half (57%) of the participating children were from minority racial and ethnic groups.

The children were randomly assigned to two groups: One included children who had their MDT visits before their pediatrician assessment and the other group included those who had their MDT visits after their pediatrician assessment.

The MDT diagnosed more than two-thirds of the children (68%) with ASD.

Sensitivity and specificity of the pediatrician assessments, compared with that of the specialist team, were 0.75 (95% confidence interval, 0.67-0.83) and 0.79 (95% CI, 0.62-0.91), respectively.
 

A look at pediatricians’ accuracy

Pediatricians reported the decisions they would have made had the child not been in the study.

• In 69% of the true-positive cases, pediatricians would have given an ASD diagnosis.
• In 44% of true-negative cases, they would have told the family the child did not have autism; in 30% of those case, they would give alternative diagnoses (most commonly ADHD and language delay).
• The pediatrician would have diagnosed ASD in only one of the seven false-positive cases and would refer those patients to a subspecialist 71% of the time.
• In false-negative cases, the pediatrician would incorrectly tell the family the child does not have autism 44% of the time.

Regarding the false-negative cases, the authors wrote, “more caution is needed for pediatricians when definitively ruling out ASD, which might result in diagnostic delays.”
 

Confidence is key

Physician confidence was also correlated with accuracy.

The authors wrote: “Among true-positive cases (MDT and pediatrician agree the child has ASD), the pediatrician was certain or very certain 80% of the time (43 cases) and the MDT was certain or very certain 96% of the time (52 cases). As such, if pediatricians conferred ASD diagnoses when feeling certain or very certain, they would make 46 correct diagnoses and 2 incorrect diagnoses.”

The high accuracy of diagnosis when physicians are confident suggests “listening to that sense of certainty is important,” Dr. Gerdts said. Conversely, these numbers show when a physician is uncertain about diagnosing ASD, they should listen to that instinct, too, and refer.

The results of the study support having general pediatricians diagnose and move forward with their patients when the signs of ASD are more definitive, saving the less-certain cases for the more resource-intensive teams to diagnose. Many states are moving toward that “tiered” system, Dr. Gerdts said.

“For many, and in fact most children, general pediatricians are pretty accurate when making an autism diagnosis,” she said.

“Let’s get [general pediatricians] confident in recognizing when this is outside their skill and ability level,” she said. “If you’re not sure, it is better to refer them on than to misdiagnose them.”

The important missing piece she said is how to support them “so they don’t feel pressure to make that call,” Dr. Gerdts said.

This project was funded by a grant from the Bloorview Research Institute, a grant from the Canadian Institutes of Health Research and a grant from the Canadian Institutes of Health. Three coauthors consult for and receive grants from several pharmaceutical companies and other organizations. Dr. Gerdts declared no relevant financial relationships.

Middle-aged adults who spend just 9 additional minutes a day participating in moderate to vigorous physical activity (MVPA) experience improved cognition in new findings that underscore the critical role brisk exercise, such as running and cycling, plays in brain health.

“Even minor differences in daily behavior appeared meaningful for cognition in this study,” researcher John J. Mitchell, MSci and PhD candidate, Medical Research Council, London, told this news organization.

The findings were published online in the Journal of Epidemiology and Community Health.
 

Research gap

Previous research has linked physical activity (PA) with increased cognitive reserve, which delays the onset of cognitive decline in later life. But disentangling the most important components of PA for cognition – such as intensity and volume – has not been well researched.

Previous studies didn’t capture sleep time, which typically takes up the largest component of the day. Sleep is “acutely relevant” when examining cognition, the investigators noted.

In addition, studies in this area often focus on just one or two activity components of the day, which “neglects the growing awareness” that movements “are all tightly interlinked,” said Mr. Mitchell.

The new study included 4,481 participants in the British Cohort Study who were born in 1970 across England, Scotland, and Wales. The participants were followed throughout childhood and adulthood.

The median age of the participants was 47 years, and they were predominantly White, female (52%), married (66%), and well educated. Most were occasional or nonrisky alcohol consumers, and half had never smoked.

The researchers collected biometric measurements and health, demographic, and lifestyle information. Participants wore a thigh-mounted accelerometer at least 7 consecutive hours a day for up to 7 days to track PA, sedentary behavior (SB), and sleep time.

The device used in the study could detect subtle movements as well as speed of accelerations, said Mr. Mitchell. “From this, we can distinguish MVPA from slow walking, standing, and sitting. It’s the current best practice for detecting the more subtle movements we make, such as brisk walking and stair climbing, beyond just ‘exercise,’ “ he added.

Light intensity PA (LIPA) describes movement such as walking and moving around the house or office, while MVPA includes activities such as brisk walking and running that accelerate the heart rate. SB, defined as time spent sitting or lying, is distinguished from standing by the thigh inclination.

On an average day, the cohort spent 51 minutes in MVPA; 5 hours, 42 minutes in LIPA; 9 hours, 16 minutes in SB; and 8 hours, 11 minutes sleeping.

Researchers calculated an overall global score for verbal memory and executive function.

The study used “compositional data analysis,” a statistical method that can examine the associations of cognition and PA in the context of all components of daily movement.

The analysis revealed a positive association between MVPA and cognition relative to all other behaviors, after adjustment for sociodemographic factors that included sex, age, education, and marital status. But the relationship lessened after further adjustment for health status – for example, cardiovascular disease or disability – and lifestyle factors, such as alcohol consumption and smoking status.

SB relative to all other movements remained positively associated with cognition after full adjustment. This, the authors speculated, may reflect engagement in cognitively stimulating activities such as reading.

To better understand the associations, the researchers used a statistical method to reallocate time in the cohort’s average day from one activity component to another.

“We held two of the components static but moved time between the other two and monitored the theoretical ramifications of that change for cognition,” said Mr. Mitchell.
 

Real cognitive change

There was a 1.31% improvement in cognition ranking compared to the sample average after replacing 9 minutes of sedentary activity with MVPA (1.31; 95% confidence interval [CI], 0.09-2.50). There was a 1.27% improvement after replacing 7 minutes of LIPA with MVPA, and a 1.2% improvement after replacing 7 minutes of sleep with MVPA.

Individuals might move up from about the 50th percentile to the 51st or 52nd percentile after just 9 minutes of more moderate to vigorous movement in place of sitting, said Mr. Mitchell. “This highlights how even very modest differences in people’s daily movement – less than 10 minutes – is linked to quite real changes in our cognitive health.”

The impact of physical activity appeared greatest on working memory and mental processes, such as planning and organization.

On the other hand, cognition declined by 1%-2% after replacing MVPA with 8 minutes of SB, 6 minutes of LIPA, or 7 minutes of sleep.

The activity tracking device couldn’t determine how well participants slept, which is “a clear limitation” of the study, said Mr. Mitchell. “We have to be cautious when trying to interpret our findings surrounding sleep.”

Another limitation is that despite a large sample size, people of color were underrepresented, limiting the generalizability of the findings. As well, other healthy pursuits – for example, reading – might have contributed to improved cognition.
 

Important findings

In a comment, Jennifer J. Heisz, PhD, associate professor and Canada research chair in brain health and aging, department of kinesiology, McMaster University, Hamilton, Ont., said the findings from the study are important.

“Through the statistical modelling, the authors demonstrate that swapping just 9 minutes of sedentary behavior with moderate to vigorous physical activity, such as a brisk walk or bike ride, was associated with an increase in cognition.”

She added that this seemed to be especially true for people who sit while at work.

The findings “confer with the growing consensus” that some exercise is better than none when it comes to brain health, said Dr. Heisz.

“Clinicians should encourage their patients to add a brisk, 10-minute walk to their daily routine and break up prolonged sitting with short movement breaks.”

She noted the study was cross-sectional, “so it is not possible to infer causation.”

The study received funding from the Medical Research Council and the British Heart Foundation. Mr. Mitchell and Dr. Heisz have disclosed no relevant financial relationships.

Middle-aged adults who spend just 9 additional minutes a day participating in moderate to vigorous physical activity (MVPA) experience improved cognition in new findings that underscore the critical role brisk exercise, such as running and cycling, plays in brain health.

“Even minor differences in daily behavior appeared meaningful for cognition in this study,” researcher John J. Mitchell, MSci and PhD candidate, Medical Research Council, London, told this news organization.

The findings were published online in the Journal of Epidemiology and Community Health.
 

Research gap

Previous research has linked physical activity (PA) with increased cognitive reserve, which delays the onset of cognitive decline in later life. But disentangling the most important components of PA for cognition – such as intensity and volume – has not been well researched.

Previous studies didn’t capture sleep time, which typically takes up the largest component of the day. Sleep is “acutely relevant” when examining cognition, the investigators noted.

In addition, studies in this area often focus on just one or two activity components of the day, which “neglects the growing awareness” that movements “are all tightly interlinked,” said Mr. Mitchell.

The new study included 4,481 participants in the British Cohort Study who were born in 1970 across England, Scotland, and Wales. The participants were followed throughout childhood and adulthood.

The median age of the participants was 47 years, and they were predominantly White, female (52%), married (66%), and well educated. Most were occasional or nonrisky alcohol consumers, and half had never smoked.

The researchers collected biometric measurements and health, demographic, and lifestyle information. Participants wore a thigh-mounted accelerometer at least 7 consecutive hours a day for up to 7 days to track PA, sedentary behavior (SB), and sleep time.

The device used in the study could detect subtle movements as well as speed of accelerations, said Mr. Mitchell. “From this, we can distinguish MVPA from slow walking, standing, and sitting. It’s the current best practice for detecting the more subtle movements we make, such as brisk walking and stair climbing, beyond just ‘exercise,’ “ he added.

Light intensity PA (LIPA) describes movement such as walking and moving around the house or office, while MVPA includes activities such as brisk walking and running that accelerate the heart rate. SB, defined as time spent sitting or lying, is distinguished from standing by the thigh inclination.

On an average day, the cohort spent 51 minutes in MVPA; 5 hours, 42 minutes in LIPA; 9 hours, 16 minutes in SB; and 8 hours, 11 minutes sleeping.

Researchers calculated an overall global score for verbal memory and executive function.

The study used “compositional data analysis,” a statistical method that can examine the associations of cognition and PA in the context of all components of daily movement.

The analysis revealed a positive association between MVPA and cognition relative to all other behaviors, after adjustment for sociodemographic factors that included sex, age, education, and marital status. But the relationship lessened after further adjustment for health status – for example, cardiovascular disease or disability – and lifestyle factors, such as alcohol consumption and smoking status.

SB relative to all other movements remained positively associated with cognition after full adjustment. This, the authors speculated, may reflect engagement in cognitively stimulating activities such as reading.

To better understand the associations, the researchers used a statistical method to reallocate time in the cohort’s average day from one activity component to another.

“We held two of the components static but moved time between the other two and monitored the theoretical ramifications of that change for cognition,” said Mr. Mitchell.
 

Real cognitive change

There was a 1.31% improvement in cognition ranking compared to the sample average after replacing 9 minutes of sedentary activity with MVPA (1.31; 95% confidence interval [CI], 0.09-2.50). There was a 1.27% improvement after replacing 7 minutes of LIPA with MVPA, and a 1.2% improvement after replacing 7 minutes of sleep with MVPA.

Individuals might move up from about the 50th percentile to the 51st or 52nd percentile after just 9 minutes of more moderate to vigorous movement in place of sitting, said Mr. Mitchell. “This highlights how even very modest differences in people’s daily movement – less than 10 minutes – is linked to quite real changes in our cognitive health.”

The impact of physical activity appeared greatest on working memory and mental processes, such as planning and organization.

On the other hand, cognition declined by 1%-2% after replacing MVPA with 8 minutes of SB, 6 minutes of LIPA, or 7 minutes of sleep.

The activity tracking device couldn’t determine how well participants slept, which is “a clear limitation” of the study, said Mr. Mitchell. “We have to be cautious when trying to interpret our findings surrounding sleep.”

Another limitation is that despite a large sample size, people of color were underrepresented, limiting the generalizability of the findings. As well, other healthy pursuits – for example, reading – might have contributed to improved cognition.
