Exposure to green space may boost cognitive function, new research suggests.

Results of a large prospective study show increasing exposure to residential green space was associated with significantly higher scores on cognitive function measures in middle-aged women, compared with women who had less exposure.

This association may be explained by a reduction in depression, researchers note. Scores for overall cognition and psychomotor speed/attention among women with high green-space exposure were equivalent to those of women an average of 1.2 years younger, they add.

“Despite the fact that the women in our study were relatively younger than those in previous studies, we were still able to detect protective associations between green space and cognition,” lead author Marcia Pescador Jimenez, PhD, assistant professor of epidemiology, Boston University School of Public Health, told this news organization.

“This may signal the public health importance of green space and the important clinical implications at the population level,” she said.

Better psychomotor speed, attention

Recent studies on the benefits of green space have shown a link between higher exposure and reduced risks for schizophrenia and ischemic stroke. Other studies have explored the link between green space and dementia and Alzheimer’s disease.

Cognitive function in middle age is associated with subsequent dementia, so Dr. Jimenez said she and her colleagues wanted to analyze the effect of residential green space on cognitive function in middle-aged women.

The study included 13,594 women (median age, 61.2 years) who are participants in the ongoing Nurses’ Health Study II, one of the largest studies to examine risk factors for chronic illness in women.

To calculate the amount of green space, researchers used the Normalized Difference Vegetation Index (NDVI), a satellite-based indicator of green vegetation around a residential address. The data were based on each participant’s 2013 residence.

After adjusting for age at assessment, race, and childhood, adulthood, and neighborhood socioeconomic status, green space was associated with higher scores on the global CogState composite (mean difference per interquartile range in green space, 0.05; 95% confidence interval, .02-.07) and psychomotor speed and attention (mean difference in score, 0.05 standard units; 95% CI, .02-.08) scales.

There was no association between green-space exposure and learning and working memory. Investigators also found no differences based on urbanicity, suggesting the benefits were similar for urban versus rural settings.
 

Specific to cognitive domains

“We were surprised to see that while our study found that higher levels of residential green space were associated with higher scores on processing speed and attention and on overall cognition, we also found that higher levels of residential green space were not associated with learning/working memory battery scores,” Dr. Jimenez said.

“This is actually in-line with previous research suggesting differing associations between green space and cognition based on the cognitive domain examined,” she added.

About 98% of participants were White, limiting the generalizability of the findings, the researchers note. There was also no information on proximity to or size of green space, or how much time individuals spent in the green space and what kinds of activities they engaged in.

Dr. Jimenez said projects examining the amount of time of green-space exposure are underway.

In addition, the researchers found lower rates of depression might contribute to the cognitive benefits associated with green-space exposure, explaining 3.95% (95% CI, .35%-7.55%) of the association between green space and psychomotor speed/attention and 6.3% (95% CI, .77%-11.81%) of the association between green space and overall cognition.

Reduced air pollution and increased physical activity, which are other factors often thought to contribute to the cognitive benefits of green space, were not significant in this study.
 

‘Interesting and novel’

Commenting on the findings, Payam Dadvand, MD, PhD, associate research professor, Barcelona Institute for Global Health, called the finding that depression may mediate green-space benefits “quite interesting and novel.”

“The results of this study, given its large sample size and its geographical coverage, adds to an emerging body of evidence on the beneficial association of exposure to green space on aging, and in particular, cognitive aging in older adults,” said Dr. Dadvand, who was not involved with the research.

The study was funded by the National Institutes of Health. Dr. Jimenez and Dr. Dadvand have reported no relevant financial relationships.

Seven physicians were among 12 medical professionals charged today by the U.S. Department of Justice with opioid distribution offenses.

In coordination with federal and state law enforcement, the DOJ charged the defendants for their involvement in the illegal distribution of opioids. At the time that they were charged with the alleged offenses, 12 of the defendants were medical professionals.

The 12 persons in eight federal districts across the country distributed more than 115 million controlled substances, including buprenorphine, clonazepam, dextroamphetamine-amphetamine, hydrocodone, morphine sulfate, oxycodone, oxymorphone, and Suboxone, per the DOJ.

“Doctors and health care professionals are entrusted with prescribing medicine responsibly and in the best interests of their patients. Today’s takedown targets medical providers across the country whose greed drove them to abandon this responsibility in favor of criminal profits,” said Anne Milgram, administrator of the Drug Enforcement Administration.
 

Medical professionals, others across six states charged

One former nurse, one business manager, and one individual who practiced medicine without a medical credential are among those listed in the indictment. These include the following:

• Eskender Getachew, MD, a Columbus, Ohio, sleep medicine specialist, was charged with unlawful distribution of controlled substances outside the use of professional practice and not for a legitimate medical practice.
• Charles Kistler, DO, an Upper Arlington, Ohio, family practice physician, was charged with unlawful distribution of controlled substances for unlawful prescribing at Midtown Family Practice Clinic in Columbus.
• Yogeshwar Gil, MBBS, a Manchester, Tenn., family medicine doctor and owner of a medical practice, was charged with conspiracy to unlawfully distribute controlled substances and maintaining a drug-involved premises. Dr. Gil was charged in connection with an alleged scheme to distribute opioids and Suboxone outside the usual course of professional practice and without a legitimate medical purpose.
• Contessa Holley, RN, a Pulaski, Tenn., former nurse and clinical director, was charged with wire fraud, aggravated identity theft, and possession of a controlled substance with intent to distribute. She’s alleged to be connected with a scheme to unlawfully obtain opioids by filling fraudulent prescriptions in the names of current and former patients who were in hospice. The indictment alleged that Ms. Holley used the patients’ hospice benefits to cover the opioids’ costs while keeping the drugs for her own use and for further distribution.
• Francene Aretha Gayle, MD, an Orlando, Fla., physician, was charged with conspiracy to unlawfully distribute controlled substances, conspiracy to commit health care fraud, health care fraud, and several substantive counts of illegally issuing opioid prescriptions. Dr. Gayle was charged along with Schara Monique Davis, a Huntsville, Ala.–based business manager. Per the indictment, Dr. Gayle and Ms. Davis operated three medical clinics in Alabama, where Dr. Gayle was the sole physician. The medical clinics billed health insurers for millions of dollars in patient visits that Dr. Gayle had supposedly conducted but during which she was allegedly absent from the clinics; other staff members conducted the visits instead. It’s alleged that Dr. Gayle presigned prescriptions for opioids that were given to patients.
• Robert Taffet, MD, a Haddonfield, N.J., orthopedic surgeon and owner of a medical practice in Sicklerville, N.J., was charged with conspiracy to unlawfully distribute controlled substances. The indictment alleges that he falsified patient files to state that he interacted with patients when he didn’t and that he issued prescriptions for opioids and other controlled substances without assessing the patients in person or by telemedicine. It’s alleged that Dr. Taffett issued prescriptions for more than 179,000 pills that were dispensed by New Jersey pharmacies between April 2020 and December 2021.
• Hau La, MD, a Brentwood, Tenn., family medicine physician and the operator of Absolute Medical Care in Smyrna, Tenn., was charged with sixteen counts of unlawful distribution of a controlled substance. The physician is alleged to have unlawfully prescribed opioids to eight patients outside the usual course of practice and without a legitimate medical purpose.
• Frederick De Mesa, of War, W.Va., practiced as a physician and used a DEA registration number that allowed him to prescribe controlled substances. Mr. De Mesa prescribed these substances without a medical license and didn’t have an active DEA registration number, according to the indictment.
• Loey Kousa, a former internist from Paintsville, Ky., was charged with unlawful distribution of controlled substances, healthcare fraud, and making false statements in connection with the delivery of health care services. The indictment alleges that the former physician issued prescriptions for opioids outside the usual course of professional practice and without a legitimate medical purpose in his capacity as owner and operator of East KY Clinic in Paintsville. He is alleged to have issued the unlawful prescriptions for patients whose treatments were covered by taxpayer-funded programs such as Medicare and Medicaid; he also billed these programs for medically unnecessary procedures for these patients.

Also included in the indictment were Jay Sadrinia, DMD, a Villa Hills, Ky., dentist, who was charged with four counts of illegal distribution of oxycodone and morphine sulfate and one count of illegal distribution of morphine sulfate that resulted in death or serious bodily injury; and Casey Kelleher, an owner-operator of Neighborhood Pharmacy in Boynton Beach, Fla., who allegedly sold large amounts of oxycodone and hydromorphone on the black market.

The Centers for Medicare & Medicaid Services’ Center for Program Integrity has taken six administrative actions against health care providers for their alleged involvement in these offenses, per the DOJ’s announcement.

“Patient care and safety are top priorities for us, and CMS has taken administrative action against six providers to protect critical resources entrusted to Medicare while also safeguarding people with Medicare,” said CMS Administrator Chiquita Brooks-LaSure.

“These actions to combat fraud, waste, and abuse in our federal programs would not be possible without the close and successful partnership of the Centers for Medicare & Medicaid Services, the Department of Justice, and the U.S. Department of Health and Human Services Office of Inspector General,” she added.

The Food and Drug Administration has cleared the first in vitro diagnostic to aid in the early detection of Alzheimer’s disease (AD).

The Lumipulse G β-Amyloid Ratio 1-42/1-40 (Fujirebio Diagnostics) test detects amyloid plaques associated with AD in adults age 55 or older who are under investigation for AD and other causes of cognitive decline.

“The availability of an in vitro diagnostic test that can potentially eliminate the need for time-consuming and expensive [positron emission tomography (PET)] scans is great news for individuals and families concerned with the possibility of an Alzheimer’s disease diagnosis,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, said in a statement.

“With the Lumipulse test, there is a new option that can typically be completed the same day and can give doctors the same information regarding brain amyloid status, without the radiation risk, to help determine if a patient’s cognitive impairment is due to Alzheimer’s disease,” he added.

In its statement, the FDA notes that there is an “unmet need for a reliable and safe test that can accurately identify patients with amyloid plaques consistent with Alzheimer’s disease.”

The agency goes on to state that this new test may eliminate the need to use PET brain scans, a “potentially costly and cumbersome option” to visualize amyloid plaques for the diagnosis of AD.

The Lumipulse test measures the ratio of β-amyloid 1-42 and β-amyloid 1-40 concentrations in human cerebral spinal fluid (CSF). A positive Lumipulse G β-amyloid Ratio (1-42/1-40) test result is consistent with the presence of amyloid plaques, similar to that revealed in a PET scan. A negative result is consistent with a negative amyloid PET scan result.

However, the FDA notes that the test is not a stand-alone assay and should be used in conjunction with other clinical evaluations and additional tests to determine treatment options.

The FDA reports that it evaluated the safety and efficacy of the test in a clinical study of 292 CSF samples from the Alzheimer’s Disease Neuroimaging Initiative sample bank.

The samples were tested by the Lumipulse G β-amyloid Ratio (1-42/1-40) and compared with amyloid PET scan results. In this clinical study, 97% of individuals with Lumipulse G β-amyloid Ratio (1-42/1-40) positive results had the presence of amyloid plaques by PET scan and 84% of individuals with negative results had a negative amyloid PET scan.

The risks associated with the Lumipulse G β-amyloid Ratio (1-42/1-40) test are mainly the possibility of false-positive and false-negative test results.

False-positive results, in conjunction with other clinical information, could lead to an inappropriate diagnosis of, and unnecessary treatment for AD.

False-negative test results could result in additional unnecessary diagnostic tests and potential delay in effective treatment for AD.

The FDA reviewed the device through the De Novo premarket review pathway, a regulatory pathway for low- to moderate-risk devices of a new type.

The agency says this action “creates a new regulatory classification, which means that subsequent devices of the same type with the same intended use may go through FDA’s 510(k) premarket process, whereby devices can obtain marketing authorization by demonstrating substantial equivalence to a predicate device.”

The Lumipulse G β-amyloid Ratio (1-42/1-40) was granted Breakthrough Device designation, a process designed to expedite the development and review of devices that may provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions.

A positive Lumipulse G β-amyloid Ratio (1-42/1-40) test result is consistent with the presence of amyloid plaques, similar to that revealed in a PET scan. A negative result is consistent with a negative amyloid PET scan result.

However, the FDA notes that the test is not a stand-alone assay and should be used in conjunction with other clinical evaluations and additional tests to determine treatment options.

The FDA reports that it evaluated the safety and efficacy of the test in a clinical study of 292 CSF samples from the Alzheimer’s Disease Neuroimaging Initiative sample bank.

The samples were tested by the Lumipulse G β-amyloid Ratio (1-42/1-40) and compared with amyloid PET scan results. In this clinical study, 97% of individuals with Lumipulse G β-amyloid Ratio (1-42/1-40) positive results had the presence of amyloid plaques by PET scan and 84% of individuals with negative results had a negative amyloid PET scan.

The risks associated with the Lumipulse G β-amyloid Ratio (1-42/1-40) test are mainly the possibility of false-positive and false-negative test results.

False-positive results, in conjunction with other clinical information, could lead to an inappropriate diagnosis of, and unnecessary treatment for AD.

False-negative test results could result in additional unnecessary diagnostic tests and potential delay in effective treatment for AD.

The FDA reviewed the device through the De Novo premarket review pathway, a regulatory pathway for low- to moderate-risk devices of a new type.

The agency says this action “creates a new regulatory classification, which means that subsequent devices of the same type with the same intended use may go through FDA’s 510(k) premarket process, whereby devices can obtain marketing authorization by demonstrating substantial equivalence to a predicate device.”

The Lumipulse G β-amyloid Ratio (1-42/1-40) was granted Breakthrough Device designation, a process designed to expedite the development and review of devices that may provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions.

The Food and Drug Administration has cleared the first in vitro diagnostic to aid in the early detection of Alzheimer’s disease (AD).

The Lumipulse G β-Amyloid Ratio 1-42/1-40 (Fujirebio Diagnostics) test detects amyloid plaques associated with AD in adults age 55 or older who are under investigation for AD and other causes of cognitive decline.

“The availability of an in vitro diagnostic test that can potentially eliminate the need for time-consuming and expensive [positron emission tomography (PET)] scans is great news for individuals and families concerned with the possibility of an Alzheimer’s disease diagnosis,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, said in a statement.

“With the Lumipulse test, there is a new option that can typically be completed the same day and can give doctors the same information regarding brain amyloid status, without the radiation risk, to help determine if a patient’s cognitive impairment is due to Alzheimer’s disease,” he added.

In its statement, the FDA notes that there is an “unmet need for a reliable and safe test that can accurately identify patients with amyloid plaques consistent with Alzheimer’s disease.”

Fecal matter may be in the fountain of youth

Yes, you read that headline correctly. New research by scientists at Quadram Institute and the University of East Anglia, both in Norwich, England, supports the claim that transferring fecal microbes might actually have some positive effects on reversing the aging process in the eyes, brain, and gut.

How do they know? Mice, of course. In the study, scientists took the gut microbes from older mice and transferred them into the younger mince. The young mice displayed inflamed signs of aging in their guts, brains, and eyes, which, we all know, decline in function as we age. What happens is a chronic inflammation of cells as we get older that can be found in the brain or gut that leads to a degenerative state over time.

When the older mice received the gut microbes from younger mice, the investigators saw the reverse: Gut, brain, and eye functionality improved. In a way, minimizing the inflammation.

There’s tons of research out there that suggests gut health is the key to a healthy life, but this study points directly to an improvement in brain and vision functionality as a result of the transfer.

Now, we’re not insinuating you get a poo transfer as you reach old age. And the shift to human studies on microbiota replacement therapy is still in the works. But this definitely is a topic to watch and could be a game changer in the age-old quest to bottle youth or at least improve quality of life as we age.

For now, the scientists did find some connections between the beneficial bacteria in the transplants and the human diet that could have similar effects, like changes in the metabolism of certain fats and vitamin that could have effects on the inflammatory cells in the eye and brain.

It’s not lying, it’s preemptive truth

Lying is bad. Bold statement, we know, but a true one. After all, God spent an entire commandment telling people not to do the whole bearing false witness thing, and God is generally known for not joking around. He’s a pretty serious dude.

In case you’ve been wandering around the desert for a while and haven’t had wifi, we have a bit of a misinformation problem these days. People lie all the time about a lot of things, and a lot of people believe the lies. According to new research, however, there are also a lot of people who recognize the lies but accept them anyway because they believe that the lies will become true in the future.

Imagine the following scenario: A friend gets a job he’s not qualified for because he listed a skill he doesn’t have. That’s bad, right? And the people the researchers interviewed agreed, at least initially. But when informed that our friend is planning on obtaining the skill in summer classes in the near future, the study participants became far more willing to excuse the initial lie.

A friend jumping the gun on training he doesn’t have yet is fairly innocuous as far as lying goes, but as the researchers found, this willingness to forgive lies because they could become true extends far further. For example, millions of people do not vote illegally in U.S. elections, nor do White people get approved for mortgages at rates 300% higher than minorities, but when asked to imagine scenarios in which those statements could be true, study participants were less likely to condemn the lie and prevent it from spreading further, especially if their political viewpoints aligned with the respective falsehood.

It seems, then, that while we may aspire to not tell lies, we take after another guy with magic powers who spent too much time in the desert: “What I told you was true, from a certain point of view.”

Consistently sleeping 7 hours per night was associated with optimal cognitive function and mental health for middle-aged adults, a new study found.

Sleep disturbances are common in older age, and previous studies have shown associations between too much or too little sleep and increased risk of cognitive decline, but the ideal amount of sleep for preserving mental health has not been well described, according to the authors of the new paper.

In the study published in Nature Aging, the team of researchers from China and the United Kingdom reviewed data from the UK Biobank, a national database of individuals in the United Kingdom that includes cognitive assessments, mental health questionnaires, and brain imaging data, as well as genetic information.

Sleep is important for physical and psychological health, and also serves a neuroprotective function by clearing waste products from the brain, lead author Yuzhu Li of Fudan University, Shanghai, China, and colleagues wrote.

The study population included 498,277 participants, aged 38-73 years, who completed touchscreen questionnaires about sleep duration between 2006 and 2010. The average age at baseline was 56.5 years, 54% were female, and the mean sleep duration was 7.15 hours.

The researchers also reviewed brain imaging data and genetic data from 39,692 participants in 2014 to examine the relationships between sleep duration and brain structure and between sleep duration and genetic risk. In addition, 156,884 participants completed an online follow-up mental health questionnaire in 2016-2017 to assess the longitudinal impact of sleep on mental health.

Both excessive and insufficient sleep was associated with impaired cognitive performance, evidenced by the U-shaped curve found by the researchers in their data analysis, which used quadratic associations.

Specific cognitive functions including pair matching, trail making, prospective memory, and reaction time were significantly impaired with too much or too little sleep, the researchers said. “This demonstrated the positive association of both insufficient and excessive sleep duration with inferior performance on cognitive tasks.”

When the researchers analyzed the association between sleep duration and mental health, sleep duration also showed a U-shaped association with symptoms of anxiety, depression, mental distress, mania, and self-harm, while well-being showed an inverted U-shape. All associations between sleep duration and mental health were statistically significant after controlling for confounding variables (P < .001).

On further analysis (using two-line tests), the researchers determined that consistent sleep duration of approximately 7 hours per night was optimal for cognitive performance and for good mental health.

The researchers also used neuroimaging data to examine the relationship between sleep duration and brain structure. Overall, greater changes were seen in the regions of the brain involved in cognitive processing and memory.

“The most significant cortical volumes nonlinearly associated with sleep duration included the precentral cortex, the superior frontal gyrus, the lateral orbitofrontal cortex, the pars orbitalis, the frontal pole, and the middle temporal cortex,” the researchers wrote (P < .05 for all).

The association between sleep duration and cognitive function diminished among individuals older than 65 years, compared with those aged approximately 40 years, which suggests that optimal sleep duration may be more beneficial in middle age, the researchers noted. However, no similar impact of age was seen for mental health. For brain structure, the nonlinear relationship between sleep duration and cortical volumes was greatest in those aged 44-59 years, and gradually flattened with older age.
 

Research supports sleep discussions with patients

“Primary care physicians can use this study in their discussions with middle-aged and older patients to recommend optimal sleep duration and measures to achieve this sleep target,” Noel Deep, MD, a general internist in group practice in Antigo, Wisc., who was not involved in the study, said in an interview.

“This study is important because it demonstrated that both inadequate and excessive sleep patterns were associated with cognitive and mental health changes,” said Dr. Deep. “It supported previous observations of cognitive decline and mental health disorders being linked to disturbed sleep. But this study was unique because it provides data supporting an optimal sleep duration of 7 hours and the ill effects of both insufficient and excessive sleep duration.

“The usual thought process has been to assume that older individuals may not require as much sleep as the younger individuals, but this study supports an optimal time duration of sleep of 7 hours that benefits the older individuals. It was also interesting to note the mental health effects caused by the inadequate and excessive sleep durations,” he added.

As for additional research, “I would like to look into the quality of the sleep, in addition to the duration of sleep,” said Dr. Deep. For example, whether the excessive sleep was caused by poor quality sleep or fragmented sleep leading to the structural and subsequent cognitive decline.
 

Study limitations

“The current study relied on self-reporting of the sleep duration and was not observed and recorded data,” Dr. Deep noted. “It would also be beneficial to not only rely on healthy volunteers reporting the sleep duration, but also obtain sleep data from individuals with known brain disorders.”

The study findings were limited by several other factors, including the use of total sleep duration only, without other measures of sleep hygiene, the researchers noted. More research is needed to investigate the mechanisms driving the association between too much and not enough sleep and poor mental health and cognitive function.

The study was supported by the National Key R&D Program of China, the Shanghai Municipal Science and Technology Major Project, the Shanghai Center for Brain Science and Brain-Inspired Technology, the 111 Project, the National Natural Sciences Foundation of China and the Shanghai Rising Star Program.

The researchers had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News.

The study findings were limited by several other factors, including the use of total sleep duration only, without other measures of sleep hygiene, the researchers noted. More research is needed to investigate the mechanisms driving the association between too much and not enough sleep and poor mental health and cognitive function.

The study was supported by the National Key R&D Program of China, the Shanghai Municipal Science and Technology Major Project, the Shanghai Center for Brain Science and Brain-Inspired Technology, the 111 Project, the National Natural Sciences Foundation of China and the Shanghai Rising Star Program.

The researchers had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose, but serves on the editorial advisory board of Internal Medicine News.
 

Symptom timelines surrounding COVID infection tend to center on either the immediate 5-day quarantine protocols for acute infection or the long-COVID symptoms that can last a month or potentially far longer.

But some patients report a “middle-range” COVID that will resolve before it becomes long COVID, yet still lasts longer than is typical for viral infections. People may return to work or daily routines, but something is off: What had been simple exercise regimens become onerous. Everyday tasks take more effort.

Does this ill-defined subset point to a “medium COVID?”

Farha Ikramuddin, MD, MHA, a physiatrist and rehabilitation specialist at the University of Minnesota and M Health Fairview in Minneapolis, points out there is no definition or diagnostic code or shared official understanding of a middle category for COVID.

“But am I seeing that? Absolutely,” she said in an interview.

“I have seen patients who are younger, healthier, [and] with not so many comorbidities have either persistence of symptoms or reappearance after the initial infection is done,” she said.

Some patients report they had very low infection or were nonsymptomatic and returned to their normal health fairly quickly after infection. Then a week later they began experiencing fatigue, lost appetite, loss of smell, and feeling full after a few bites, Dr. Ikramuddin said.

Part of the trouble in categorizing the space between returning to normal after a week and having symptoms for months is that organizations can’t agree on a timeline for when symptoms warrant a “long-COVID” label.

For instance, the Centers for Disease Control and Prevention defines it as 4 or more weeks after infection. The World Health Organization defines it as starting 3 months after COVID-19 symptom onset.

“I’m seeing ‘medium COVID’ – as one would call it – in younger and healthier patients. I’m also noticing that these symptoms are not severe enough to warrant stopping their job or changing their job schedules,” Dr. Ikramuddin said.

They go back to work, she said, but start noticing something is off.

“I am seeing that.”

“I discharge at least two patients a week from my clinic because they have moved on and no longer have symptoms,” Dr. Ikramuddin said.

In a story from Kaiser Health News published last month, WHYY health reporter Nina Feldman writes: “What I’ve come to think of as my ‘medium COVID’ affected my life. I couldn’t socialize much, drink, or stay up past 9:30 p.m. It took me 10 weeks to go for my first run – I’d been too afraid to try.”

She described a dinner with a friend after ending initial isolation protocols: “One glass of wine left me feeling like I’d had a whole bottle. I was bone-achingly exhausted but couldn’t sleep.”
 

Medical mystery

Dr. Ikramuddin notes the mechanism behind prolonged COVID-19 symptoms is still a medical mystery.

“In one scenario,” she said, “the question is being asked about whether the virus is staying dormant, similar to herpes zoster or HIV.”

“Right now, instead of getting more answers, we’re getting more questions,” Dr. Ikramuddin  said.

Mouhib Naddour, MD, a pulmonary specialist with Sharp HealthCare in San Diego, said he’s seeing that it’s taking some patients who have had COVID longer to recover than it would for other viral infections.

Some patients fall between those recovering within 2-3 weeks and patients having long COVID. Those patients in the gap could be lumped into a middle-range COVID, he told this news organization.

“We try to put things into tables and boxes but it is hard with this disease,” Dr. Naddour said.

He agrees there’s no medical definition for “medium” COVID, but he said the idea should bring hope for patients to know that, if their symptoms are persisting they don’t necessarily have long COVID – and their symptoms may still disappear.

“This is an illness that may take longer to completely recover from,” he said. “The majority of patients we’re seeing in this group could be healthy young patients who get COVID, then 2-3 weeks after they test negative, still have lingering symptoms.”
 

Common symptoms

Some commonly reported symptoms of those with enduring illness, which often overlap with other stages of COVID, are difficulty breathing, chest tightness, dry cough, chest pain, muscle and joint pain, fatigue, difficulty sleeping, and mood swings, Dr. Naddour said. 

“We need to do an extensive assessment to make sure there’s no other problem causing these symptoms,” he said.

Still, there is no set timeline for the medium-COVID range, he noted, so checking in with a primary care physician is important for people experiencing symptoms.
 

It’s a continuum, not a category

Fernando Carnavali, MD, coordinator for Mount Sinai’s Center for Post-COVID Care in New York, said he is not ready to recognize a separate category for a “medium” COVID.

He noted that science can’t even agree on a name for lasting post-COVID symptoms, whether it’s “long COVID” or “long-haul COVID,” “post-COVID syndrome” or “post-acute sequelae of COVID-19 (PASC ).” There’s no agreed-upon pathophysiology or biomarker.

“That creates these gaps of understanding on where we are,” Dr. Carnavali said in an interview.

He said he understands people’s need to categorize symptoms, but rather than a middle ground he sees a continuum.

It doesn’t mean what others may call COVID’s middle ground doesn’t exist, Dr. Carnavali said: “We are in the infancy of defining this. Trying to classify them may create more anxiety.”

The clinicians interviewed for this story report no relevant financial relationships.

New surveillance data from the Vaccine Adverse Event Reporting System (VAERS) confirm a small but statistically significant increased risk for Guillain-Barré syndrome (GBS) in the 3 weeks after receipt of the Janssen/Johnson & Johnson COVID-19 vaccine.

The Janssen vaccine (Ad26.COV2.S) is a replication-incompetent adenoviral vector vaccine.

The data show no increased risk of GBS with the Pfizer (BNT162b2) or Moderna (mRNA-1273) shots – both mRNA vaccines.

“Our findings support the current guidance from U.S. health officials that preferentially recommend use of mRNA COVID-19 vaccines for primary and booster doses,” Nicola Klein, MD, PhD, with Kaiser Permanente Vaccine Study Center, Oakland, Calif., told this news organization.

“Individuals who choose to receive Janssen/J&J COVID-19 vaccine should be informed of the potential safety risks, including GBS,” Dr. Klein said.

The study was published online in JAMA Network Open.
 

Eleven cases

Between mid-December 2020 and mid-November 2021, roughly 15.1 million doses of COVID-19 vaccine were administered to nearly 7.9 million adults in the United States.

This includes roughly 483,000 doses of the Janssen vaccine, 8.8 million doses of the Pfizer vaccine, and 5.8 million doses of the Moderna vaccine.

The researchers confirmed 11 cases of GBS after the Janssen vaccine.

The unadjusted incidence of GBS (per 100,000 person-years) was 32.4 in the first 21 days after the Janssen vaccine – substantially higher than the expected background rate of 1 to 2 cases per 100,000 person-years.

There were 36 confirmed cases of GBS after mRNA vaccines. The unadjusted incidence in the first 21 days after mRNA vaccination was 1.3 per 100,000 person-years, similar to the overall expected background rate.

In an adjusted head-to-head comparison, GBS incidence during the 21 days after receipt of the Janssen vaccine was 20.6 times higher than the GBS incidence during the 21 days after the Pfizer or Moderna mRNA vaccines, amounting to 15.5 excess cases per million Janssen vaccine recipients.

Most cases of GBS after the Janssen vaccine occurred during the 1- to 21-day risk interval, with the period of greatest risk in the 1-14 days after vaccination.

The findings of this analysis of surveillance data of COVID-19 vaccines are “consistent with an elevated risk of GBS after primary Ad26.COV2.S vaccination,” the authors wrote.
 

Novel presentation?

The researchers note that nearly all individuals who developed GBS after the Janssen vaccine had facial weakness or paralysis, in addition to weakness and decreased reflexes in the limbs, suggesting that the presentation of GBS after COVID-19 adenoviral vector vaccine may be novel.

“More research is needed to determine if the presentation of GBS after adenoviral vector vaccine differs from GBS after other exposures such as Campylobacter jejuni, and to investigate the mechanism for how adenoviral vector vaccines may cause GBS,” Dr. Klein and colleagues said.

“The Vaccine Safety Datalink continues to conduct safety surveillance for all COVID-19 vaccines, including monitoring for GBS and other serious health outcomes after vaccination,” Dr. Klein said in an interview.

This study was supported by the Centers for Disease Control and Prevention. Dr. Klein reported receiving grants from Pfizer research support for a COVID vaccine clinical trial as well as other unrelated studies, grants from Merck, grants from GlaxoSmithKline, grants from Sanofi Pasteur, and grants from Protein Science (now Sanofi Pasteur) outside the submitted work.

The risk for dementia goes up in patients with atrial fibrillation (AFib), but some evidence suggests that risk can be blunted with therapies that restore sinus rhythm. However, a new cohort study suggests that the treatment effect’s magnitude might depend on the rhythm control strategy. It hinted that AFib catheter ablation might be more effective than pharmacologic rhythm control alone at cutting the risk for dementia.

The case-matched study of more than 38,000 adults with AFib saw a 41% reduction (P < .0001) in risk for dementia among those who underwent catheter ablation after attempted rhythm control with antiarrhythmic drugs (AAD), compared with those managed with pharmacologic rhythm control therapy alone.

The observational study comprising 20 years of data comes with big limitations and can’t say for sure whether catheter ablation is better than AAD-only at cutting the dementia risk in AFib. But it and other evidence support the idea, which has yet to be explored in a randomized fashion.

In a secondary finding, the analysis showed a similar reduction in dementia risk from catheter ablation, compared with AAD, in women and in men by 40% and 45%, respectively (P < .0001 for both). The findings are particularly relevant “given the higher life-long risk of dementia among women and the lower likelihood that women will be offered ablation, which has been demonstrated repeatedly,” Emily P. Zeitler, MD, MHS, Dartmouth-Hitchcock Medical Center, Lebanon, New Hampshire, told this news organization. “I think this is another reason to try to be more generous in offering ablation to women.”

Management of AFib certainly evolved in important ways from 2000 to 2021, the period covered by the study. But a sensitivity analysis based on data from 2010 to 2021 showed “no meaningful differences” in the results, said Dr. Zeitler, who is slated to present the findings April 30 at the Heart Rhythm Society 2022 Scientific Sessions, conducted virtually and live in San Francisco.

Dr. Zeitler acknowledged that the observational study, even with its propensity-matched ablation and AAD cohorts, can only hint at a preference for ablation over AAD for lowering risk for AFib-associated dementia. “We know there’s unmeasured and unfixable confounding between those two groups, so we see this really as hypothesis-generating.”

It was “a well-done analysis,” and the conclusion that the dementia risk was lower with catheter ablation is “absolutely correct,” but only as far as the study and its limitations allow, agreed David Conen, MD, MPH, McMaster University, Hamilton, Ontario, who is not a coauthor.

“Even with propensity matching, you can get rid of some sorts of confounding, but you can never get rid of all selection bias issues.” That, he said when interviewed, takes randomized trials.

Dr. Conen, who is studying cognitive decline in AFib as a SWISS-AF trial principal investigator, pointed to a secondary finding of the analysis as evidence for such confounding. He said the ablation group’s nearly 50% drop (P < .0001) in competing risk for death, compared with patients managed with AAD, isn’t plausible.

He said the ablation group’s nearly 50% drop (P < .0001) in competing risk for death, compared with patients managed with AAD, isn’t plausible.

The risk for dementia goes up in patients with atrial fibrillation (AFib), but some evidence suggests that risk can be blunted with therapies that restore sinus rhythm. However, a new cohort study suggests that the treatment effect’s magnitude might depend on the rhythm control strategy. It hinted that AFib catheter ablation might be more effective than pharmacologic rhythm control alone at cutting the risk for dementia.

The case-matched study of more than 38,000 adults with AFib saw a 41% reduction (P < .0001) in risk for dementia among those who underwent catheter ablation after attempted rhythm control with antiarrhythmic drugs (AAD), compared with those managed with pharmacologic rhythm control therapy alone.

The observational study comprising 20 years of data comes with big limitations and can’t say for sure whether catheter ablation is better than AAD-only at cutting the dementia risk in AFib. But it and other evidence support the idea, which has yet to be explored in a randomized fashion.

In a secondary finding, the analysis showed a similar reduction in dementia risk from catheter ablation, compared with AAD, in women and in men by 40% and 45%, respectively (P < .0001 for both). The findings are particularly relevant “given the higher life-long risk of dementia among women and the lower likelihood that women will be offered ablation, which has been demonstrated repeatedly,” Emily P. Zeitler, MD, MHS, Dartmouth-Hitchcock Medical Center, Lebanon, New Hampshire, told this news organization. “I think this is another reason to try to be more generous in offering ablation to women.”

Management of AFib certainly evolved in important ways from 2000 to 2021, the period covered by the study. But a sensitivity analysis based on data from 2010 to 2021 showed “no meaningful differences” in the results, said Dr. Zeitler, who is slated to present the findings April 30 at the Heart Rhythm Society 2022 Scientific Sessions, conducted virtually and live in San Francisco.

Dr. Zeitler acknowledged that the observational study, even with its propensity-matched ablation and AAD cohorts, can only hint at a preference for ablation over AAD for lowering risk for AFib-associated dementia. “We know there’s unmeasured and unfixable confounding between those two groups, so we see this really as hypothesis-generating.”

It was “a well-done analysis,” and the conclusion that the dementia risk was lower with catheter ablation is “absolutely correct,” but only as far as the study and its limitations allow, agreed David Conen, MD, MPH, McMaster University, Hamilton, Ontario, who is not a coauthor.

“Even with propensity matching, you can get rid of some sorts of confounding, but you can never get rid of all selection bias issues.” That, he said when interviewed, takes randomized trials.

Elevated concentrations of carbon monoxide (CO) due to air pollution increases the risk of epileptic seizures, a unique new study suggests.

The link between daily outdoor CO exposure and seizure risk was particularly evident for subclinical seizures – those in patients with abnormal electroencephalography (EEG) signals but no clinical symptoms.

“Our findings suggest that people with epilepsy should avoid high CO exposure to reduce potential seizure risk,” said study investigator Zhuying Chen, PhD candidate, department of biomedical engineering, University of Melbourne.

The study was published online in Epilepsia.
 

Pollution’s impact on brain health

Emerging evidence indicates air pollution affects brain health and may increase the risk of hospitalization or outpatient visits for epilepsy. However, little is known about the effect of pollution on the occurrence of epileptic seizures.

The study used two independent long-term seizure datasets – the NeuroVista (NV) study and the Seer App seizure diary (SD). In the NeuroVista study, researchers recorded continuous intracranial iEEG from patients with refractory focal epilepsy who had been implanted with a personal seizure advisory device that wirelessly recorded seizures on an external device.

The SD dataset included diaries documenting self-reported seizures, seizure cycles, and medication adherence.

Researchers collected data on hourly concentrations of outdoor CO, nitrogen dioxide (NO₂), particulate matter of 10 μm or less in diameter (PM₁₀), ozone (O₃), and sulfur dioxide (SO₂). The levels were measured at air quality monitoring stations in Australia.

Investigators aggregated hourly observations into daily mean data. All daily concentrations of CO and SO₂ and at least 95% of daily concentrations of NO₂, O₃, and PM₁₀ were within Australian air quality standards, said Mr. Chen.

The study included 49 participants, with epilepsy data on 15 patients in the NeuroVista study and on 34 from the SD dataset.

Overall, 6,692 epileptic seizures on 3,639 seizure days were recorded during 23,349 follow-up days from 2010 to 2012 (NV dataset) and 2018 to 2021 (SD dataset).

The investigators found a significant positive association between CO concentrations and epileptic seizure risks. The relative risk (RR) was 1.04 (95% confidence interval, 1.01–1.07; P < .01) for an interquartile range (IQR) increase of CO (0.13 parts per million).
 

Sex differences

There were no significant relationships for the other four air pollutants. However, Mr. Chen noted that Australia has very low air pollution levels; most usually are within World Health Organization air quality guidelines.

“Our findings may not be generalized to other countries with high air pollution levels,” said Mr. Chen. He noted that the relatively small number of patients in the study may limit the statistical power to detect some associations.

The study showed that females had a significantly increased risk of epileptic seizures when exposed to elevated CO (RR, 1.05; 95% CI, 1.01–1.08; P < .05) and NO₂ (RR, 1.09; 95% CI, 1.01–1.16; P < .05) concentrations. There were no significant associations in males for any air pollutants.

Differences in outdoor activities and behaviors such as smoking and exercise may lead to variations in environmental exposure and help explain the sex differences, said Mr. Chen. These differences may also be due to the study’s limited sample size.

Analyzing the two datasets separately, the researchers found there was a significant association between CO concentration and epileptic seizure risk in the NV dataset (RR, 1.10; 95% CI, 1.03–1.17; P < .01).

There were no significant associations in the SD dataset for any air pollutants. This may be because only clinical seizures – those associated with evident symptoms – are self-reported, said Mr. Chen. He also noted that seizure diaries may be unreliable.

In the NV dataset, the epileptic seizure risk was significantly increased when only subclinical seizures were considered (RR, 1.20; 95% CI, 1.12–1.28; P < .001) for an IQR increase of CO concentration.

The risk was significantly decreased by 13% for subclinical seizures with an IQR increase of PM₁₀ and by 9% for subclinical seizures with an IQR increase of SO₂ concentrations.

These negative associations should be interpreted with caution, inasmuch as the associations were not robust in subsequent subgroup and sensitivity analyses, said Mr. Chen.

There were no significant associations when considering clinical seizures for any air pollutants.

The positive association for subclinical but not clinical seizures suggests that low-level CO exposure may not be strong enough to directly trigger clinical seizures, said Mr. Chen.

Although previous research has demonstrated adverse neurologic effects of exposure to air pollutants, most studies were based on hospital databases or registers. Thus, they may have missed seizures that did not lead to hospital admission.
 

Unclear mechanism

The exact mechanisms linking air pollution to seizures are unclear but probably involve the synergistic interaction of multiple pathways, said Mr. Chen. “Air pollution may affect brain metabolism, alter the immune response of the brain, and induce oxidative stress and neuroinflammation, causing the brain to be more susceptible to seizures,” he noted.

This is the first study to investigate seizure rates through intracranial EEG signals and self-reported seizure diaries. It’s also the first to look into the impact of pollutants at low concentration levels on subclinical seizures.

However, the study has some limitations. Self-reported seizures in the SD dataset might underestimate the influence of air pollution on seizures. The study used postal codes as proxies for exposure to pollution, which could introduce measurement errors and underestimate associations.

In addition, Mr. Chen noted that seizures from the NeuroVista dataset were recorded from patients with drug-resistant focal epilepsy. “Whether our findings can be generalized to other epilepsy types needs further investigation.”

The study could have important clinical and public health implications. For example, said Mr. Chen, it’s possible that seizure risk could be reduced through behavioral interventions, such as avoiding being outside or using an air filtration system when pollutant levels are high.

“Clinicians could counsel their patients to avoid the potential risk of high carbon monoxide exposure,” he said.

CO exposure could be a new factor for seizure risk forecasting, which could reduce the uncertainty of seizures and help guide epilepsy management, Mr. Chen added.

The study was supported by the Melbourne Monash Consciousness Research Seed Funding and an Australian National Health and Medical Research Council Ideas grant. Mr. Chen has disclosed no relevant financial relationships.

Rates of premature return to play (RTP) among student athletes following a sport-related concussion (SRC) have dropped substantially since 2011, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.

“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.

“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.

The study was published in Canadian Family Physician.
 

Differences by sex

The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.

Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.

There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).

Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.

The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
 

More concussions coming?

Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.

In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.

“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.

“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.

A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.
 

“Very positive shifts”

Commenting on the findings, Nick Reed, PhD, Canada research chair in pediatric concussion and associate professor of occupational science and occupational therapy, University of Toronto, said that sports medicine physicians are seeing “very positive shifts” in concussion awareness and related behaviors such as providing education, support, and accommodations to students within the school environment. “More and more teachers are seeking education to learn what a concussion is and what to do to best support their students with concussion,” he said. Dr. Reed was not involved in the current study.

Indeed, this increasing awareness led to the development of a concussion education tool for teachers – SCHOOLFirst – although Dr. Reed did acknowledge that not all teachers have either the knowledge or the resources they need to optimally support their students with concussion. In the meantime, to reduce the risk of injury, Dr. Reed stressed that it is important for students to wear equipment appropriate for the game being played and to play by the rules.

“It is key to play sports in a way that is fair and respectful and not [engage] in behaviors with the intent of injuring an opponent,” he stressed. It is also important for athletes themselves to know the signs and symptoms of concussion and, if they think they have a concussion, to immediately stop playing, report how they are feeling to a coach, teacher, or parent, and to seek medical assessment to determine if they have a concussion or not.

“The key here is to focus on what the athlete can do after a concussion rather than what they can’t do,” Dr. Reed said. After even a few days of complete rest, students with a concussion can gradually introduce low levels of physical and cognitive activity that won’t make their symptoms worse. This activity can include going back to school with temporary accommodations in place, such as shorter school days and increased rest breaks. “When returning to school and to sport after a concussion, it is important to follow a stepwise and gradual return to activities so that you aren’t doing too much too fast,” Dr. Reed emphasized.

The study was conducted without external funding. Dr. Carson and Dr. Reed reported no conflicts of interest.

Rates of premature return to play (RTP) among student athletes following a sport-related concussion (SRC) have dropped substantially since 2011, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.

“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.

“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.

The study was published in Canadian Family Physician.
 

Differences by sex

The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.

Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.

There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).

Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.

The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
 

More concussions coming?

Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.

In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.

“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.

“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.

A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.
 

“Very positive shifts”

Commenting on the findings, Nick Reed, PhD, Canada research chair in pediatric concussion and associate professor of occupational science and occupational therapy, University of Toronto, said that sports medicine physicians are seeing “very positive shifts” in concussion awareness and related behaviors such as providing education, support, and accommodations to students within the school environment. “More and more teachers are seeking education to learn what a concussion is and what to do to best support their students with concussion,” he said. Dr. Reed was not involved in the current study.

Indeed, this increasing awareness led to the development of a concussion education tool for teachers – SCHOOLFirst – although Dr. Reed did acknowledge that not all teachers have either the knowledge or the resources they need to optimally support their students with concussion. In the meantime, to reduce the risk of injury, Dr. Reed stressed that it is important for students to wear equipment appropriate for the game being played and to play by the rules.

“It is key to play sports in a way that is fair and respectful and not [engage] in behaviors with the intent of injuring an opponent,” he stressed. It is also important for athletes themselves to know the signs and symptoms of concussion and, if they think they have a concussion, to immediately stop playing, report how they are feeling to a coach, teacher, or parent, and to seek medical assessment to determine if they have a concussion or not.

“The key here is to focus on what the athlete can do after a concussion rather than what they can’t do,” Dr. Reed said. After even a few days of complete rest, students with a concussion can gradually introduce low levels of physical and cognitive activity that won’t make their symptoms worse. This activity can include going back to school with temporary accommodations in place, such as shorter school days and increased rest breaks. “When returning to school and to sport after a concussion, it is important to follow a stepwise and gradual return to activities so that you aren’t doing too much too fast,” Dr. Reed emphasized.

The study was conducted without external funding. Dr. Carson and Dr. Reed reported no conflicts of interest.
