A serious bout of COVID-19 can prompt a serious loss of brain power, new research warns, triggering a drop in IQ that's equivalent to aging from 50 to 70 in a matter of months.
"Previous research has indicated that people who have recovered from COVID-19 may suffer from lasting problems in terms of their ability to concentrate and problem solve," noted study author Adam Hampshire. He's an...
Certain personality traits may make older adults more or less vulnerable to waning memory and thinking skills, a new study suggests.
The study, of nearly 2,000 older adults, found that those high on the "conscientious" scale — organized, self-disciplined and productive — were less likely to develop mild cognitive impairment. That refers to subtler problems with memory and other mental...
Want to preserve all those precious memories, including your first kiss and how you felt the first time you got behind the wheel of a car?
If you do, start moving: New research shows that when sedentary older adults started to exercise, they showed improvements in episodic memory, or the ability to vividly recall meaningful moments and events.
Imagine a closet filled with treasures accumulated during a lifetime of rich experiences. Now, imagine going into that closet to find one specific object.
Only maybe you get distracted by another, more enticing item from your past. Or you find the object you're seeking but it's intertwined with six similar items, and withdrawing the one will drag out the entire tangle.
People hospitalized for COVID-19 are not necessarily out of the woods once they're discharged: Many land in the hospital again in the months afterward, a large U.K. study finds.
The researchers found that in the 10 months after leaving the hospital, COVID-19 patients were more than twice as likely to be hospitalized or die, compared to the general population. And even compared with people...
Older adults who maintain a steady weight as they age are less likely to experience rapid cognitive decline, regardless of how much they weigh to start, new research suggests.
“There’s something about maintaining weight and BMI that seems to reflect some health resilience,” said study author Michal Schnaider Beeri, a professor of psychiatry at Icahn Mount Sinai in New York City. (BMI is...
It's a move that could severely limit the number of people taking the controversial new Alzheimer's drug Aduhelm: Medicare on Tuesday proposed to only cover the cost of the pricey medication for people enrolled in approved clinical trials.
A final decision on coverage is expected later this year.
The drug costs $28,200 per year, but that cost will only be covered for participan...

Exercise helps you stay fit, hale and hearty, and researchers say it may also help you stave off dementia and Alzheimer's disease. Now they have a better understanding of the hidden benefits that aid the brain.
Older folks who are more physically active have higher levels of a protein that promotes better communication between the brain's synapses, a new study reports.
Following a months-long and unprecedented review, Medicare officials expect to announce within the next couple of weeks whether the program will cover the controversial Alzheimer's drug Aduhelm. The drug's benefits are in question and its annual price tag tops $28,000.
The U.S. Centers for Medicare and Medicaid Services (CMS) tend to cover with little fanfare most drugs approved by its s...
Low-dose aspirin neither reduces nor increases the risk of dementia in adults with type 2 diabetes, a new study finds.
"This is reassuring that an increase in the risk of dementia is unlikely for the millions of people worldwide who regularly take aspirin to protect against the risk of heart attack and stroke," according to study author Jane Armitage, of the University of Oxford in Englan...
Eating lots of fruits, veggies, beans and other foods with inflammation-cooling properties may lower your odds of developing dementia as you age.
But, if your diet is loaded with pro-inflammatory foods, you may be up to three times more likely to experience memory loss and issues with language, problem-solving and other thinking skills as you age, new research suggests.
Certain changes in a part of the brain stem, visible in scans, might be a potential early indicator of Alzheimer's disease, a new study suggests.
Using different brain imaging techniques, researchers found that lesser "integrity" in the brain stem region was linked to a faster decline in memory and thinking in older adults, as well as certain brain changes seen in early Alzheimer's.
Older adults who use certain blood pressure drugs may retain more of their memory skills as they age, a new study suggests.
Researchers found the benefit among older people taking medications that are allowed past the "blood-brain barrier," which is a border of specialized cells that prevents toxic substances from crossing into the brain.
Smoking pot appears to affect teens' brain development, altering it in ways that could diminish their reasoning, decision-making and memory skills as they age, a new study reports.
Brain scans of about 800 teenagers found that those who started smoking pot tended to have increased thinning of the cerebral cortex -- the outer layer of the brain responsible for thought, perception and langu...
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 ...
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...
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.
After a concussion, women may be at heightened risk of lasting physical and mental symptoms, a new study finds.
The study of 2,000 concussion sufferers found that women were more likely than men to still have some symptoms one year later. The problems included fuzzy memory and difficulty concentrating, as well as headaches, dizziness or fatigue.
