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...
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...
People who suffer a traumatic brain injury (TBI) have a significantly higher risk for stroke for years afterward, U.K. researchers say.
Previous studies have linked brain injury with a long-term risk of neurological diseases including dementia, Parkinson's and epilepsy, and it's been suggested that it's also an independent risk factor for stroke.
A combination of hearing and vision loss is tied to an increased risk of mental decline and dementia, but having just one of those impairments isn't connected with a higher risk, a new South Korean study finds.
It's not clear why a diminishing of both senses, but not just one, would raise dementia risks, but the study's leader had a theory that's tied to the importance of socializing in ...
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...
A new study shows just how devastating a diagnosis of mental decline can be: Researchers found that rates of suicide rise sharply in the months after such news is delivered.
The study of almost 148,000 older U.S. Department of Veterans Affairs patients, mostly men, looked at diagnoses for mild cognitive impairment (MCI), which is often (but not always) a precursor to dementia.
About 7 out of 10 Alzheimer's patients wound up free of the brain plaques that are a hallmark of the disease after treatment with a potentially breakthrough experimental drug, clinical trial results show.
The drug, donanemab, also significantly slowed the patients' brain decline, according to findings published March 13 in the New England Journal of Medicine.
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 ...
Sustaining just one head injury may up your chances of developing dementia decades later by 25%, and this risk increases with each subsequent head injury, new research suggests.
"Head injury is not the only risk factor for dementia as high blood pressure and diabetes, among others, also contribute significantly to dementia risk, but head injury is one risk factor for dementia that is modi...
Black and Hispanic Americans already face higher risks for dementia than the general population. Many also believe they'd get worse dementia care compared to white patients, according to a new Alzheimer's Association special report.
Older Black Americans are about twice as likely to have Alzheimer's or another form of dementia as older white people, and older Hispanics are about 1.5 times...
If you want to protect yourself against dementia, heart disease and cancer, you might want to get your protein from nuts instead of juicy red steaks.
New research shows that older women who ate the most plant protein were 21% less likely to suffer a dementia-related death and 12% less likely to die from heart disease, compared with women who ate little to no plant protein.
White matter damage in the brains of adults with frontotemporal dementia is even greater than that seen in Alzheimer's disease patients, a new study shows.
Frontotemporal dementia often affects people younger than 65, mainly causing personality and behavior changes and problems with language, rather than memory. The researchers assessed areas of brain damage called white matter hyperinten...
Older adults who get little sleep each night may be at heightened risk of dementia or earlier death, a new study suggests.
Researchers found that among 2,600 older Americans, those who were deemed "short sleepers" -- catching no more than five hours of sleep at night -- were more likely to develop dementia or die over the next five years.
"Prediabetes" -- where blood sugar levels are high but not yet tipped over into full-blown diabetes -- may pose a threat to brain health, new British research suggests.
"As an observational study, it cannot prove higher blood sugar levels cause worsening brain health. However, we believe there is a potential connection that needs to be investigated further," said study lead author Victori...

Although Alzheimer's disease is a devastating diagnosis that is better delivered earlier rather than later, new research suggests poor patients living in rural areas may not have access to the specialists who could spot the first signs of memory declines.
The team from Vanderbilt University in Nashville, Tenn., led by Sayeh Nikpay, now an assistant professor at the University of Minnesota...
Severe frailty significantly increases the risk of death in COVID-19 patients, British researchers say.
In their new study, the investigators analyzed data from more than 5,700 COVID-19 patients at 55 hospitals in 12 countries. They found that those who were severely frail were three times more likely to die than those who weren't frail.
A shortage of neurologists in rural parts of the United States means that people in those areas are less likely to receive specialized care for conditions such as stroke, dementia and back pain, a new study claims.
"Neurologists in the United States are not evenly spread out, which affects whether patients can see a neurologist for certain conditions like dementia and stroke," said study ...
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...
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...
Strong sleeping pills known as "Z-drugs" may increase the risk of falls, fractures and stroke among people with dementia, British researchers report.
People with dementia can have trouble sleeping and are often prescribed drugs such as zaleplon (Sonata), zolpidem (Ambien) and zopiclone to help them nod off, but higher doses of these drugs can have negative effects.
Older adults who aren't interested or enthusiastic about their usual activities may have a higher risk of developing dementia, new research suggests.
The nine-year study of more than 2,000 older adults -- average age 74 -- found that people with severe apathy (a lack of interest or concern) were 80% more likely to develop dementia during the study period than those with low apath...
