High triglycerides, widely known as an enemy of the aging heart, may not be as threatening to older adults' brains, new research suggests.

The study, of over 80,000 older adults, found those with triglycerides in the "high-normal" or moderately high range were less likely to develop dementia, versus their peers with lower triglyceride levels.

Over six years, 3% of older folks with t...

A variety of risks can make it more likely that someone develops Alzheimer's disease or other dementias.

Now you can add neighborhood environment to that list. A new study finds low income levels and a lack of green spaces are among the factors that can harm brain health.

"Social determinants of health have a major impact on cognition, as well as cardiovascular and cerebrovascular h...

Mid-life isn't too late to make a dietary change to preserve brain health.

Women who started following the diet known as DASH (Dietary Approaches to Stop Hypertension) to lower their blood pressure were about 17% less likely to report memory loss and other signs of mental decline decades later, a new study re...

Scientists have long wondered whether depression leads to less sleep or whether a lack of sleep triggers depression.

A new study suggests it's the latter: Getting less than five hours of sleep a night may raise the risk of developing depressive symptoms.

"We have this chicken or egg scenario between suboptimal sleep duration and depression, they frequently co-occur, but which comes ...

Dementia can take a big bite out of an American's bank account, robbing 60% of a patient's net worth in the eight years after a diagnosis, a new study says.

The average dementia patient will also see a doubling of out-of-pocket health care expenses in those first eight years, said researchers who studied thousands of seniors with and without the brain disorder.

"We found a prof...

Adults with attention-deficit/hyperactivity disorder (ADHD) are nearly three times more likely to develop dementia than other adults, a new study suggests.

The results also indicate that treatment with ADHD medication may help reduce their dementia risk. No clear uptick in dementia risk was found among ADHD patients who received psychostimulant medication.

"More than 3% of the adult...

Researchers have developed an antibody that can reduce Alzheimer's-like brain damage in lab mice -- inspired by the case of one woman with remarkable resistance to the disease.

The work, by researchers at Mass General Brigham, Harvard Medical School in Boston, and elsewhere, began a few years ago, with the case of a woman in Colombia who had shown "extreme protection" from Alzheimer's dis...

While HDL cholesterol is considered the "good" kind for heart and brain health, too much or too little of it may up a person's risk of dementia, new research suggests.

"This study is especially informative because of the large number of participants and long follow-up,"noted study author Maria Glymour, of Boston ...

Hot flashes and night sweats top the list of bothersome symptoms for women going through menopause.

Now, a new study suggests that hot flashes, especially during sleep, may be more than a nuisance: They may foreshadow Alzheimer's disease.
