Sleep disorders may increase the odds for dementia in survivors of traumatic brain injury, new research suggests.
The study included nearly 713,000 patients who were free of dementia when they were treated for traumatic brain injury (TBI) between 2003 and 2013. The severity of their brain injuries varied, and nearly six in 10 were men. Their median age was 44, meaning half were older, hal...
MONDAY, May 24, 2021 (HealthDay News) – As researchers work to learn more about COVID-19 and so-called long-haulers, a new study suggests "brain fog" can persist and even worsen for those who were infected months before.
Long-haulers continue to have symptoms long after their COVID diagnosis, and these symptoms can be mental as well as physical.
New insight into why you don't remember your earliest years of life is provided in a new study.
"A fundamental mystery about human nature is that we remember almost nothing from birth through early childhood, yet we learn so much critical information during that time -- our first language, how to walk, objects and foods, and social bonds," said senior author Nick Turk-Browne, a professor ...
THURSDAY, May 20, 2021 (HealthDay News) -- If you've ever wished you had an extra hand to accomplish a task, never fear, scientists are working on that. But a new study raises questions about how such technology could affect your brain.
The findings come from ongoing research into a 3D-printed robotic thumb known as "Third Thumb." It's worn on a person's dominant hand, ...
An estimated 9 million Americans turn to prescription pills when they can't sleep, but a new study of middle-aged women finds taking the drugs for a year or longer may do little good.
Comparing a group of about 200 women who were medicated for sleep problems with over 400 women who had sleeping problems but did not take medication, researchers from Brigham and Women's Hospital in Boston f...
It may be possible to treat the thinking problems that result from repeated hits to the head, a new laboratory study suggests.
The new experiments with mice are the first to offer a molecular analysis of what happens in the brain after repetitive but mild blows to the head, said researcher Mark Burns. He is head of the Laboratory for Brain Injury and Dementia at Georgetown University, in ...
Neurological problems are occurring in a very high percentage of hospitalized COVID-19 patients -- and what's worse, those symptoms foretell a bad end for many sufferers, a new study finds.
About four out of five people sick enough to be hospitalized for COVID-19 suffer some sort of neurological problem, ranging from headache and a loss of sense of smell to confusion, delirium, stroke a...
Could having heart disease risk factors in childhood sow the seeds of thinking declines in middle-age?
It looks like it might, new research claims.
"I think it was not so big of a surprise for us, but maybe for the scientific community who have been focusing mainly on the midlife risk factors and old-age cognition," said study co-author Suvi Rovio. She is senior researcher of cardio...
A bit of booze may help protect your heart by reducing stress-related brain activity, a new study suggests.
"The thought is that moderate amounts of alcohol may have effects on the brain that can help you relax, reduce stress levels and, perhaps through these mechanisms, lower the incidence of cardiovascular disease," said lead author Dr. Kenechukwu Mezue, a nuclear cardiology fellow at M...
Parkinson's disease is widely seen as a movement disorder, but it can cause an array of symptoms, including hallucinations. Now a new study has shed light on what is happening in the brain during those disturbances.
The study focused on Parkinson's patients who have so-called presence hallucinations -- a false feeling that another person is nearby.
Kids exposed to air pollution may be at risk for mental illness in early adulthood, a new study suggests.
Researchers found that young adults in Britain who were exposed to higher levels of traffic-related air pollutants during their childhood and teen years were prone to develop symptoms of mental illness later. Nitrogen oxides were a particular problem, the study authors reported.
That college degree may be useful in many ways, but new research suggests it probably won't keep your brain from shrinking with age.
Over the years, a number of studies have suggested that education might buffer people against age-related declines in memory and thinking. But those findings did not prove a cause-and-effect relationship.
In the new study, researchers asked whether peo...
Alzheimer's disease and traumatic brain injury appear to affect the brain in similar ways, according to a study that may point to new ways to identify people at high risk for Alzheimer's.
"These findings are the first to suggest that cognitive impairment following a traumatic brain injury is useful for predicting the magnitude of Alzheimer's-like brain degradation," said study author Andr...
Music hath charms to soothe you off to slumber, new research suggests.
The study found that calming tunes at bedtime seem to help older people struggling with insomnia.
"We found music therapy was effective for older adults with sleep disturbance," said study co-author Yen-Chin Chen, an associate professor of nursing at National Cheng Kung University in Tainan, Taiwan.
Black and Hispanic survivors of a bleeding stroke are more likely than white survivors to have changes in small blood vessels in the brain that increase the risk of another bleeding stroke, researchers say.
'Bleeding' strokes, also called hemorrhagic stroke, comprise about 13% of all strokes. They occur when an artery in the brain leaks or ruptures.
As if the headaches and stuffy nose aren't bad enough, chronic sinus trouble often leaves patients foggy-headed and depressed. Now, new research suggests one possible reason why: Sinusitis may trigger changes in brain activity.
"Chronic sinusitis is incredibly common," said study lead author Dr. Aria Jafari. Upwards of 11% of all Americans are affected, added Jafari, an assistant profess...
Here's some good news for aging athletes: If you played high school football, you're no more likely than others to have problems with concentration, memory or depression in middle age, according to a new study.
"Men who played high school football did not report worse brain health compared with those who played other contact sports, noncontact sports, or did not participate in sports dur...
'Bleeding' stroke patients with COVID-19 are more than twice as likely to die as those without COVID-19, new research shows.
For the study, a research team from the University of Utah analyzed data from 568 hospitals in the United States. They compared a control group of more than 23,300 patients without COVID-19 who suffered a bleeding (hemorrhagic) stroke to 771 COVID-19 patients who ha...
In very rare cases, children infected with the new coronavirus can develop a severe illness known as multisystem inflammatory syndrome (MIS-C). Now, research finds that these young patients often develop neurologic symptoms along with the respiratory issues they might face.
These neurologic symptoms were present in half of children who were hospitalized with MIS-C, U.K. researchers say.

School-age children with autism may be faring better than commonly thought, with most "doing well" in at least some aspects of development, a new study suggests.
The study, of 272 children with autism spectrum disorder (ASD), found that nearly 80% were doing well in at least one of five developmental areas by age 10. Nearly one-quarter were doing well in four of those areas.
Brain activity increases when you start to learn a new language, but slows down as you become more proficient, a new, small study finds.
"In the first few months, you can quantitatively measure language-skill improvement by tracking brain activations," study co-author Kuniyoshi Sakai, a neuroscientist at the University of Tokyo, said in a school news release.
Regular aerobic exercise increases blood flow to the brain, which may help slow mental decline in older adults, a new, small study suggests.
Researchers from University of Texas Southwestern Medical Center looked at 70 men and women diagnosed with mild cognitive impairment (MCI). This means there are slight changes to the brain that affect memory, decision-making or reasoning skills. In m...
It's not unusual for a fictional character to ring such a chord that their story shapes your life.
Think of educators inspired by Robin Williams' character in "Dead Poets Society," lawyers drawn to the profession by Perry Mason or Atticus Finch, or health professionals motivated by the doctors on "ER" or "Grey's Anatomy."
Now researchers think they've figured out why fiction can so ...
People really do vary in how fast they age, and the divergence starts in young adulthood, a new study suggests.
The researchers found that by the tender age of 45, people with a faster pace of "biological aging" were more likely to feel, function and look far older than they actually were. And that relative sprint toward old age began in their 20s.
It's already being taken by millions to help ward off heart issues, and now preliminary research hints that daily low-dose aspirin might also cut your odds of contracting COVID-19.
As the Israeli research team noted, aspirin is an anti-inflammatory and previous studies have shown that it may help the immune system combat some viral infections. According to the researchers, aspirin was wid...
