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.
Your eyes may be a window into the health of your brain, a new study indicates.
Researchers found that older adults with the eye disease retinopathy were at increased risk of having a stroke, as well as possible symptoms of dementia. And on average, they died sooner than people their age without the eye condition.
Retinopathy refers to a disease the retina, the light-sensing tissue ...
Living in a noisy neighborhood with less green space negatively affects teens' sleep, which may lead to poorer memory and thinking skills, according to a pair of studies.
In a study on residential environment, researchers found that as noise levels steadily increased, so too did the time needed for teens to fall asleep. They also didn't sleep as long as kids in quieter, greener neighborho...
Think your dog is smart? New research suggests one way to find out.
Most dogs can't learn words without extensive training, but a few with exceptional abilities learn words without any formal training, researchers report. They learn words simply by playing with their owners.
The team of Hungarian researchers investigated how quickly two of these talented pooches could learn new word...
A rare brain disease that causes loss of language skills doesn't lead to memory loss, a new study finds.
The condition is called primary progressive aphasia and about 40% of people who have it have underlying Alzheimer's disease, according to researchers. Their study was published online Jan. 13 in the journal Neurology.
"While we knew that the memories of people with prima...
Moderate-to-vigorous physical activity in middle age and beyond might help keep your brain healthy, a new study suggests.
"Our study suggests that getting at least an hour and 15 minutes of moderate-to-vigorous-intensity physical activity a week or more during midlife may be important throughout your lifetime for promoting brain health and preserving the actual structure of your brain," s...
As COVID-19 continues to spread and people face more isolation than usual, researchers are noting the impact of loneliness on the brain.
A new study from McGill University in Montreal found a tell-tale signature in the brains of lonely people. Specifically, they discovered variations in the volume of different brain regions and how those regions communicate across brain networks.
Some older folks are still sharp as tacks and dementia-free well into their 80s and beyond. Now German researchers have uncovered a possible reason why: Their genes may help them fend off protein build-up in the brain.
The finding is based on a study of brain images of 94 participants, all aged 80 or older. They were characterized by the amount of tau protein tangles and beta-amyloid prot...
High blood pressure can begin to take a toll on memory and thinking skills as early as middle age, new Brazilian research warns.
And you won't be spared simply by keeping high blood pressure at bay until you hit your golden years, because the study found that even those who hadn't developed high blood pressure until becoming seniors still experienced a faster decline in thinking skills th...
Even before signs of Alzheimer's disease or dementia appear, people are prone to make poor financial decisions, a new study finds.
Older people diagnosed with dementia or Alzheimer's were more likely to miss credit card payments as early as six years before their diagnosis, compared with similar people without dementia (about 8% versus 7%), the researchers found.
Older adults exposed to air pollution might have a heightened risk of abnormal "plaque" accumulation in the brain, a new study suggests.
Plaques refer to clumps of protein called beta-amyloid that build up in the brains of people with Alzheimer's disease. In the new study, researchers found that among older adults with memory and thinking problems, those exposed to higher levels of air po...
Older adults with memory problems may progress to Alzheimer's more quickly if they are also suffering from anxiety symptoms, a preliminary study suggests.
It's common for people with Alzheimer's disease to have mood symptoms, including anxiety and depression. And some research has suggested those symptoms can, in older people, act as early indicators of the dementia process.
