Six healthy lifestyle habits linked to slowed memory decline
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.
Participants were also stratified by APOE genotype into APOE4 carriers and noncarriers.
Demographic and other items of health information, including the presence of medical illness, were used as covariates. The researchers also included the “learning effect of each participant as a covariate, due to repeated cognitive assessments.”
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.
Memory decline occurred faster in APOE4 vesus non-APOE4 carriers (0.002 points/year [95% confidence interval, 0.001-0.003]; P = .007).
But APOE4 carriers with favorable and average lifestyles showed slower memory decline (0.027 [0.023-0.031] and 0.014 [0.010-0.019], respectively), compared with those with unfavorable lifestyles. Similar findings were obtained in non-APOE4 carriers.
Those with favorable or average lifestyle were respectively almost 90% and 30% less likely to develop dementia or MCI, compared with those with an unfavorable lifestyle.
The authors acknowledge the study’s limitations, including its observational design and the potential for measurement errors, owing to self-reporting of lifestyle factors. Additionally, some participants did not return for follow-up evaluations, leading to potential selection bias.
Nevertheless, the findings “might offer important information for public health to protect older [people] against memory decline,” they note – especially since the study “provides evidence that these effects also include individuals with the APOE4 allele.”
‘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.

Even one head injury boosts all-cause mortality risk
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.

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.

Don’t cross the friends line with patients
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.

Pediatricians, specialists largely agree on ASD diagnoses
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.

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.
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.

Nine more minutes a day of vigorous exercise tied to better cognition
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.

Flu, other common viruses linked to neurologic disease
People hospitalized with viral infections like the flu are more likely to have disorders that degrade the nervous system, like Alzheimer’s or Parkinson’s, later in life, a new analysis shows.
The viruses included influenza, encephalitis, herpes, hepatitis, pneumonia, meningitis, and shingles. Those viruses were linked to one or more of these conditions: Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis (ALS), dementia, and multiple sclerosis.
The authors of the study, which was published this month in the journal Neuron, cautioned that their findings stopped short of saying the viruses caused the disorders.
“Neurodegenerative disorders are a collection of diseases for which there are very few effective treatments and many risk factors,” study author and National Institutes of Health researcher Andrew B. Singleton, PhD, said in a news release from the NIH. “Our results support the idea that viral infections and related inflammation in the nervous system may be common – and possibly avoidable – risk factors for these types of disorders.”
For the study, two data sets were analyzed with a combined 800,000 medical records for people in Finland and the United Kingdom. People who were hospitalized with COVID-19 were excluded from the study.
Generalized dementia was the condition linked to the most viruses. People exposed to viral encephalitis, which causes brain inflammation, were 20 times more likely to be diagnosed with Alzheimer’s, compared with those who were not diagnosed with that virus.
Both influenza and pneumonia were also associated with all of the neurodegenerative disorder diagnoses studied, with the exception of multiple sclerosis. The researchers found that severe flu cases were linked to the most risks.
“Keep in mind that the individuals we studied did not have the common cold. Their infections made them so sick that they had to go to the hospital,” said study author and NIH researcher Michael Nalls, PhD. “Nevertheless, the fact that commonly used vaccines reduce the risk or severity of many of the viral illnesses observed in this study raises the possibility that the risks of neurodegenerative disorders might also be mitigated.”
The researchers examined the time from when someone was infected with a virus to the time when they were diagnosed with one of the neurodegenerative disorders. They found that most had a high risk within 1 year of infection. But in six scenarios, there were significant links that showed up after 5-15 years.
The authors wrote that vaccines that are available for some of the viruses studied may be a way to reduce the risk of getting diseases that degrade the nervous system.

The authors wrote that vaccines that are available for some of the viruses studied may be a way to reduce the risk of getting diseases that degrade the nervous system.

Minorities with epilepsy blocked from receiving ‘highest quality of care’
, new research shows.
Even after controlling for epilepsy severity, comorbid conditions, and other factors that might affect medication choice, researchers found that newer medication use was 29% less likely in Black patients, 23% less likely in Native Hawaiian and other Pacific Islander patients, and 7% less likely in Hispanic patients, compared with White individuals.
“I hope that clinicians will see from our findings that minoritized patients with epilepsy face a myriad of barriers in receiving the highest quality of care, including ASM use,” said lead investigator Wyatt P. Bensken, PhD, adjunct assistant professor of Population and Quantitative Health Sciences at Case Western Reserve University, Cleveland. “Considering your patients’ barriers, and how that influences their care – including ASM selection – will be critical to helping reduce these population-level inequities.”
The study was published online in Neurology Clinical Practice.
A prompt for practice change
For the study, researchers used Medicaid claims for more than 78,000 people who had filled at least two prescriptions for an ASM between 2010 and 2014.
Most patients were White (53.4%); 22.6% were Black; 11.9% were Hispanic; 1.6% were Asian; 1.5% were Native Hawaiian or other Pacific Islander; 0.6% American Indian or Alaskan Native; and 8.3% were classified as “other.”
One-quarter of participants were taking an older ASM, such as carbamazepine, phenytoin, and valproate. About 65% were taking second-generation ASMs, including gabapentin, levetiracetam, and zonisamide. A little less than 10% were taking lacosamide, perampenel, or another third-generation ASM.
Compared with White patients, newer medication prescriptions were significantly less likely in Black individuals (adjusted odds ratio, 0.71; 95% confidence interval, 0.68-0.75), Native Hawaiian or other Pacific Islanders (aOR, 0.77; 95% CI, 0.67-0.88), and Hispanic patients (aOR, 0.93; 95% CI, 0.88-0.99).
Third-generation ASMs were used by 10.7% of White patients versus 6% of Black individuals and 5.1% of American Indian or Alaskan Native patients.
Researchers also found that taking a second-generation ASM was associated with better treatment adherence (aOR, 1.17; 95% CI, 1.11-1.23) and that patients on newer ASMs were more than three times as likely to be under the care of a neurologist (aOR, 3.26; 95% CI, 3.13-3.41).
The findings draw attention to racial inequities surrounding access to medication and specialists and subspecialists, Dr. Bensken said. Identifying specific barriers and developing solutions is the long-range goal, he added.
“In the interim, increasing the attention to these inequities will, we hope, prompt changes across practices,” Dr. Bensken said.
A ‘wake-up call’
Commenting on the findings, Joseph Sirven, MD, professor of neurology at the Mayo Clinic Florida, Jacksonville, said the results were “striking” because newer ASMs are generally the go-to for most physicians who treat epilepsy.
“Use of first-generation ASMs is typically reserved [for] if one runs out of options,” Dr. Sirven said.
This study and others like it should serve as a “wake-up call” for clinicians, Dr. Sirven added.
“This study is important because it shows that whether we realize it or not, race and ethnicities are playing a role in ASM, and this is related to financial access to newer-generation drugs,” he said. “Similar findings are seen in impoverished countries where first-generation ASM drugs are routinely used because of drug pricing.”
More to explore
Also commenting on the study, Scott Mintzer, MD, a professor and director of the Epilepsy Monitoring Unit at Thomas Jefferson University, Philadelphia, said using first-generation ASMs as a proxy for quality of care is “a very innovative concept.”
“From that perspective, the finding that racial minority patients are more likely to be on a first-generation drug is not surprising. But after that it gets far more complicated to interpret,” he added.
Neither adherence nor care by a neurologist was different in a consistent direction within the various minority populations, Dr. Mintzer noted. In addition, Black patients were as likely to see a neurologist as White patients but still more likely to be on a first-generation drug.
There are also a few caveats to the findings that should be considered, Dr. Mintzer added. First, the sample included only Medicaid recipients, nearly 35% of whom had a comorbid psychosis. Those and other characteristics of the study pool suggest participants aren’t representative of the United States population as a whole. Second, significant shifts in ASM use have occurred since the study data cutoff in 2014, none of which are reflected in these findings.
“So, I don’t think we can really say how to address this yet,” Dr. Mintzer said. “There’s a lot to explore about whether this is still occurring, how generalizable these findings are, and what they might be due to, as there are a host of potential explanations, which the authors themselves acknowledge.”
The study was funded by the U.S. Centers for Disease Control and Prevention and the National Institute on Minority Health and Health Disparities. Dr. Bensken has received support for this work from NIMHD and serves on the Editorial Board of the journal Neurology. Dr. Sirven and Mintzer report no relevant financial relationships.

Severe health diagnoses drive suicide risk
Individuals diagnosed with a severe physical health condition were significantly more likely to commit suicide at 6 months and at 1 year later, based on data from more than 47 million individuals in a national database.
Previous smaller studies have shown a link between increased risk for suicide and a range of health conditions including cancer, coronary heart disease, neurologic conditions, diabetes, and osteoporosis, Vahé Nafilyan, PhD, of the Office for National Statistics, Newport, England, and colleagues wrote.
However, large-scale population-level studies of the association between specific diagnoses and suicide are lacking, they said.
In a study published in The Lancet Regional Health–Europe, the researchers reviewed a dataset that combined the 2011 Census, death registration records, and the Hospital Episode Statistics. The study population included 47,354,696 individuals aged 6 years and older living in England in 2017. The mean age of the study population was 39.6 years, and 52% were female. The researchers examined deaths that occurred between Jan. 1, 2017, and Dec. 31, 2021.
The health conditions included in the analysis were low-survival cancers, chronic ischemic heart disease, chronic obstructive pulmonary disease, and degenerative neurological disease.
The diagnosis of any of these conditions significantly increased the risk for suicide compared with controls. The highest risk appeared within 6 months of a diagnosis or first treatment, but the increased risk persisted at 1 year.
The suicide rate among low-survival cancer patients was 16.6 per 100,000 patients, compared with 5.7 per 100,000 controls; at 1 year, these rates were 21.6 and 9.5 per 100,000 patients and controls, respectively.
For COPD patients, the suicide rate at 6 months after diagnosis was 13.7 per 100,000 patients versus 5.6 per 100,000 matched controls; the suicide rates at 1 year were 22.4 per 100,000 patients and 10.6 per 100,000 matched controls.
The suicide rate at 6 months for individuals diagnosed with chronic ischemic heart disease was 11.0 per 100,000 patients and 4.2 per 100,000 matched controls; at 1 year, the suicide rates were 16.1 per 100,000 patients and 8.8 per 100,000 matched controls.
The 1-year suicide rate was especially high among patients with degenerative neurological conditions (114.5 per 100,000 patients); however, the estimate was considered imprecise because of the rarity of these diseases and subsequent low number of suicides, the researchers noted.
The results support data from previous studies showing links between increased risk of suicide and severe physical conditions, the researchers wrote. Patterns of suicide were similar between men and women and after adjusting for sociodemographic factors.
The findings were limited by the inability to fully control for a history of depression or self-harm, and by the imprecise estimates given the rare occurrence of suicide overall, the researchers noted. Other limitations included the late registration of deaths from external causes and the focus only on suicides that occurred in England and Wales, meaning that individuals who traveled abroad for assisted suicide were not captured in the dataset.
“Further research is needed to understand the mechanisms driving the elevated risk of suicide and help provide the best support to these patients,” the researchers concluded.
However, the current results enhance the literature with a large, population-based review of the elevated suicide risk among individuals newly diagnosed with severe health conditions, and reflect the need for better support for these patients to help with coping, they said.
The study was funded by the Office for National Statistics. The researchers reported no relevant financial relationships.

The longevity gene: Healthy mutant reverses heart aging
Everybody wants a younger heart
As more people live well past 90, scientists have been taking a closer look at how they’ve been doing it. Mostly it boiled down to genetics. You either had it or you didn’t. Well, a recent study suggests that doesn’t have to be true anymore, at least for the heart.
Scientists from the United Kingdom and Italy found an antiaging gene in some centenarians that has shown possible antiaging effects in mice and in human heart cells. A single administration of the mutant antiaging gene, they found, stopped heart function decay in middle-aged mice and even reversed the biological clock by the human equivalent of 10 years in elderly mice.
When the researchers applied the antiaging gene to samples of human heart cells from elderly people with heart problems, the cells “resumed functioning properly, proving to be more efficient in building new blood vessels,” they said in a written statement. It all kind of sounds like something out of Dr. Frankenstein’s lab.
I want to believe … in better sleep
The “X-Files” theme song plays. Mulder and Scully are sitting in a diner, breakfast laid out around them. The diner is quiet, with only a few people inside.
Mulder: I’m telling you, Scully, there’s something spooky going on here.
Scully: You mean other than the fact that this town in Georgia looks suspiciously like Vancouver?
Mulder: Not one person we spoke to yesterday has gotten a full night’s sleep since the UFO sighting last month. I’m telling you, they’re here, they’re experimenting.
Scully: Do you really want me to do this to you again?
Mulder: Do what again?
Scully: There’s nothing going on here that can’t be explained by the current research. Why, in January 2023 a study was published revealing a link between poor sleep and belief in paranormal phenomena like UFOS, demons, or ghosts. Which probably explains why you’re on your third cup of coffee for the morning.
Mulder: Scully, you’ve literally been abducted by aliens. Do we have to play this game every time?
Scully: Look, it’s simple. In a sample of nearly 9,000 people, nearly two-thirds of those who reported experiencing sleep paralysis or exploding head syndrome reported believing in UFOs and aliens walking amongst humanity, despite making up just 3% of the overall sample.
Furthermore, about 60% of those reporting sleep paralysis also reported believing near-death experiences prove the soul lingers on after death, and those with stronger insomnia symptoms were more likely to believe in the devil.
Mulder: Aha!
Scully: Aha what?
Mulder: You’re a devout Christian. You believe in the devil and the soul.
Scully: Yes, but I don’t let it interfere with a good night’s sleep, Mulder. These people saw something strange, convinced themselves it was a UFO, and now they can’t sleep. It’s a vicious cycle. The study authors even said that people experiencing strange nighttime phenomena could interpret this as evidence of aliens or other paranormal beings, thus making them even more susceptible to further sleep disruption and deepening beliefs. Look who I’m talking to.
Mulder: Always with the facts, eh?
Scully: I am a doctor, after all. And if you want more research into how paranormal belief and poor sleep quality are linked, I’d be happy to dig out the literature, because the truth is out there, Mulder.
Mulder: I hate you sometimes.
It’s ChatGPT’s world. We’re just living in it
Have you heard about ChatGPT? The artificial intelligence chatbot was just launched in November and it’s already more important to the Internet than either Vladimir Putin or “Rick and Morty.”
What’s that? You’re wondering why you should care? Well, excuuuuuse us, but we thought you might want to know that ChatGPT is in the process of taking over the world. Let’s take a quick look at what it’s been up to.
“ChatGPT bot passes law school exam”
“ChatGPT passes MBA exam given by a Wharton professor”
“A freelance writer says ChatGPT wrote a $600 article in just 30 seconds”
And here’s one that might be of interest to those of the health care persuasion: “ChatGPT can pass part of the U.S. Medical Licensing Exam.” See? It’s coming for you, too.
The artificial intelligence known as ChatGPT “performed at >50% accuracy across [the three USMLE] examinations, exceeding 60% in most analyses,” a group of researchers wrote on the preprint server medRxiv, noting that 60% is usually the pass threshold for humans taking the exam in any given year.
ChatGPT was not given any special medical training before the exam, but the investigators pointed out that another AI, PubMedGPT, which is trained exclusively on biomedical domain literature, was only 50.8% accurate on the USMLE. Its reliance on “ongoing academic discourse that tends to be inconclusive, contradictory, or highly conservative or noncommittal in its language” was its undoing, the team suggested.
To top it off, ChatGPT is listed as one of the authors at the top of the medRxiv report, with an acknowledgment at the end saying that “ChatGPT contributed to the writing of several sections of this manuscript.”
We’ve said it before, and no doubt we’ll say it again: We’re doomed.

I want to believe … in better sleep
The “X-Files” theme song plays. Mulder and Scully are sitting in a diner, breakfast laid out around them. The diner is quiet, with only a few people inside.
Mulder: I’m telling you, Scully, there’s something spooky going on here.
Scully: You mean other than the fact that this town in Georgia looks suspiciously like Vancouver?
Mulder: Not one person we spoke to yesterday has gotten a full night’s sleep since the UFO sighting last month. I’m telling you, they’re here, they’re experimenting.
Scully: Do you really want me to do this to you again?
Mulder: Do what again?
Scully: There’s nothing going on here that can’t be explained by the current research. Why, in January 2023 a study was published revealing a link between poor sleep and belief in paranormal phenomena like UFOS, demons, or ghosts. Which probably explains why you’re on your third cup of coffee for the morning.
Mulder: Scully, you’ve literally been abducted by aliens. Do we have to play this game every time?
Scully: Look, it’s simple. In a sample of nearly 9,000 people, nearly two-thirds of those who reported experiencing sleep paralysis or exploding head syndrome reported believing in UFOs and aliens walking amongst humanity, despite making up just 3% of the overall sample.
Furthermore, about 60% of those reporting sleep paralysis also reported believing near-death experiences prove the soul lingers on after death, and those with stronger insomnia symptoms were more likely to believe in the devil.
Mulder: Aha!
Scully: Aha what?
Mulder: You’re a devout Christian. You believe in the devil and the soul.
Scully: Yes, but I don’t let it interfere with a good night’s sleep, Mulder. These people saw something strange, convinced themselves it was a UFO, and now they can’t sleep. It’s a vicious cycle. The study authors even said that people experiencing strange nighttime phenomena could interpret this as evidence of aliens or other paranormal beings, thus making them even more susceptible to further sleep disruption and deepening beliefs. Look who I’m talking to.
Mulder: Always with the facts, eh?
Scully: I am a doctor, after all. And if you want more research into how paranormal belief and poor sleep quality are linked, I’d be happy to dig out the literature, because the truth is out there, Mulder.
Mulder: I hate you sometimes.
It’s ChatGPT’s world. We’re just living in it
Have you heard about ChatGPT? The artificial intelligence chatbot was just launched in November and it’s already more important to the Internet than either Vladimir Putin or “Rick and Morty.”
What’s that? You’re wondering why you should care? Well, excuuuuuse us, but we thought you might want to know that ChatGPT is in the process of taking over the world. Let’s take a quick look at what it’s been up to.
“ChatGPT bot passes law school exam”
“ChatGPT passes MBA exam given by a Wharton professor”
“A freelance writer says ChatGPT wrote a $600 article in just 30 seconds”
And here’s one that might be of interest to those of the health care persuasion: “ChatGPT can pass part of the U.S. Medical Licensing Exam.” See? It’s coming for you, too.
The artificial intelligence known as ChatGPT “performed at >50% accuracy across [the three USMLE] examinations, exceeding 60% in most analyses,” a group of researchers wrote on the preprint server medRxiv, noting that 60% is usually the pass threshold for humans taking the exam in any given year.
ChatGPT was not given any special medical training before the exam, but the investigators pointed out that another AI, PubMedGPT, which is trained exclusively on biomedical domain literature, was only 50.8% accurate on the USMLE. Its reliance on “ongoing academic discourse that tends to be inconclusive, contradictory, or highly conservative or noncommittal in its language” was its undoing, the team suggested.
To top it off, ChatGPT is listed as one of the authors at the top of the medRxiv report, with an acknowledgment at the end saying that “ChatGPT contributed to the writing of several sections of this manuscript.”
We’ve said it before, and no doubt we’ll say it again: We’re doomed.
Everybody wants a younger heart
As more people live well past 90, scientists have been taking a closer look at how they’ve been doing it. Mostly it boiled down to genetics. You either had it or you didn’t. Well, a recent study suggests that doesn’t have to be true anymore, at least for the heart.
Scientists from the United Kingdom and Italy found an antiaging gene in some centenarians that has shown possible antiaging effects in mice and in human heart cells. A single administration of the mutant antiaging gene, they found, stopped heart function decay in middle-aged mice and even reversed the biological clock by the human equivalent of 10 years in elderly mice.
When the researchers applied the antiaging gene to samples of human heart cells from elderly people with heart problems, the cells “resumed functioning properly, proving to be more efficient in building new blood vessels,” they said in a written statement.

Despite ongoing challenges, experts are optimistic about the future of MS therapy
Prior to 1993, a multiple sclerosis (MS) diagnosis could often mean an abbreviated lifespan marked by progressive disability and loss of function. That changed when the Food and Drug Administration approved interferon beta-1b (Betaseron) in 1993, which revolutionized MS therapy and gave hope to the entire MS community.
"The most surprising thing about MS management over the last 30 years is that we’ve been able to treat MS – especially relapsing MS,” said Fred D. Lublin, MD, professor of neurology and director of the Corinne Goldsmith Dickinson Center for Multiple Sclerosis in Mount Sinai in New York. “The approval of interferon was a major therapeutic advancement because it was the first treatment for what was an untreatable disease.”
Mark Gudesblatt, MD, medical director of the Comprehensive MS Care Center of South Shore Neurologic Associates in Patchogue, N.Y., agrees.
“For people with MS, it’s an extraordinarily lucky and amazingly optimistic time,” he said. “Before interferon beta-1b, MS was called ‘the crippler of young adults’ because more than 50% of these people would require a walker 10 years after diagnosis, and a large number of young and middle-age patients with MS were residing in nursing homes.”
According to Dr. Lublin, the emergence of the immunomodulating therapies placed MS at the leading edge of neurotherapeutics. Interferon beta-1b laid the foundation for new therapies such as another interferon (interferon beta-1a; Avonex), glatiramer acetate (Copaxone), and many other effective therapies with different mechanisms of action. Since the emergence of the first therapy, more than 20 oral and infusion agents with moderate to high efficacy have come to market for relapsing MS.
Treatment options, treatment challenges
Dr. Gudesblatt points out that having numerous therapies from which to choose is both a blessing and a problem.
“The good news is that there are so many options for treating relapsing MS today,” he said. “The bad news is there are so many options. Like doctors who are treating high blood pressure, doctors managing patients with MS often struggle to determine which medication is best for individual patients.”
Despite the promise of vastly better outcomes and prolonged lifespan, MS therapy still faces its share of challenges, including effective therapies for progressive MS and reparative-restorative therapies.
“Choice in route of administration and timing of administration allow for larger and broader discussions to try to meet patients’ needs,” Dr. Lublin said. “We’ve been extremely successful at treating relapses, but not as successful in treating progressive disease.”
The unclear mechanism of pathogenesis amplifies the challenges clinicians face in successful management of patients with MS. For example, experts agree that the therapies for progressive MS have only proven moderately effective at best. The paucity of therapies available for progressive MS and the limitations of the current therapies further limit the outcomes.
Looking ahead
Experts expressed optimistic views about the future of MS therapy as a whole. From Dr. Lublin’s perspective, the MS community stands to gain valuable insights from emerging research focused on treating progressive disease along with new testing to understand the underlying mechanism of progressive disease. Enhanced understanding of the underlying pathogenesis of progressive MS coupled with the ability to diagnose MS – such as improved MRI techniques – have facilitated this process.
Among the therapies with novel mechanisms of action in the pipeline include agents that generate myelin sheath repair. Another potential therapeutic class on the horizon, known as TPK inhibitors, addresses the smoldering of the disease. With these and other therapeutic advances, Dr. Lublin hopes to see better control of progressive disease.
An agenda for the future
In addition, barriers such as access to care, cost, insurance coverage, and tolerance remain ongoing stressors that will likely continue weighing on the MS community and its stakeholders into the future.
Dr. Gudesblatt concluded that advancing MS outcomes in the future hinges on several additional factors.
“We need medicines that are better for relapse and progression; medicines that are better tolerated and safer; and better medicine to address the underlying disease as well as its symptoms. But we also need to appreciate, recognize, and address cognitive impairment along the MS continuum and develop effective reparative options,” he said.
Regardless, he emphasized that these “amazing advancements” in MS therapy have renewed hope that research may identify and expand effective treatments for multiple other neurologic conditions such as muscular dystrophies, neurodegenerative and genetic disorders, movement disorders, and dysautonomia-related diseases. Like MS, all of these conditions have limited therapies, some of which have minimal efficacy. But none of these other disorders has disease-modifying therapies currently available.
‘A beacon of hope’
“MS is the beacon of hope for multiple disease states because it’s cracked the door wide open,” Dr. Gudesblatt said. Relapse no longer gauges the prognosis of today’s MS patient – a prognosis both experts think will only continue to improve with forthcoming innovations.
While the challenges for MS still exist, the bright future that lies ahead may eventually eclipse them.
