A lot of people wear watches that count their every step as they try to move more.

Now, a new study finds that getting more of those steps each day, along with moderate-to-vigorous physical exercise, could cut the risk of dementia and thinking impairments for women.

For women aged 65 or older, each additional 31 minutes per day of moderate-to-vigorous physical activity was associat...

A good physical workout benefits an older brain. So does socializing. Put those two together and the payoff may be even bigger.

Researchers in Japan found that link in a new study that looked at exercising solo and in a group.

"Exercise is manageable for many older people, and we saw cognitive benefits from it compared with those who don't exercise," said study senior author

Memory loss is the most common symptom associated with Alzheimer’s disease — the terrifying prospect of slowly forgetting yourself and everything around you.

But people who exhibit memory loss early on in their dementia actually have a slower rate of decline than those who develop other symptoms earlier, a

Could losing your hearing as you age be a harbinger of dementia?

Maybe, suggests new research that found that older people who had trouble hearing were more likely to develop dementia down the road. But there's good news with the bad: Hearing aids — which are now available over-the-counter at much lower prices — may reduce this risk.

“There is evidence that hearing loss c...

Social isolation is a substantial risk factor for dementia in older adults, according to a pair of studies that add evidence to past research on this threat.

But these new studies offer a potential solution: using technology to encourage older adults to text and email to stay in touch.

Although the studies don’t prove lack of regular social contact causes dementia, researchers sai...

Six minutes of high-intensity exercise might prolong the lifespan of a healthy brain, perhaps delaying the start of Alzheimer's and Parkinson’s diseases, a new, small study suggests.

Researchers found that short but intense cycling increased the production of a protein called brain-derived neurotrophic factor (BDNF), which is essential for brain formation, learning and memory. It's tho...

Many conditions cause memory issues, and early detection is essential for effective treatment, according to a national Alzheimer’s disease organization.

The Alzheimer’s Foundation of America (AFA) encourages people to get a memory screening in the new year.

The foundation offers free, confidential virtual memory screenings. It doesn’t set a minimum age and there are no insura...

The U.S. Food and Drug Administration on Friday approved a second Alzheimer's drug, lecanemab, despite reports of rare brain bleeds linked to use of the drug in some patients.

However, the FDA pointed to the drug's benefits, as well.

“Alzheimer’s disease immeasurably incapacitates the lives of those who suffer from it and has devastating effects on their loved ones,” Dr. Bill...

Lecanemab: It's an experimental medication that's been shown in trials to slow cognitive decline in people with Alzheimer’s disease.

It's also up for accelerated approval by the U.S. Food and Drug Administration, with a decision expected by Jan. 6.

However, the drug has also been linked to two deaths from brain bleeds among people who’ve used it in trials, so safety concerns c...

The U.S. Food and Drug Administration's approval process for the controversial Alzheimer's drug Aduhelm was "rife with irregularities," despite lingering doubts about the power of the pricey medication to slow the disease down, a Congressional report released Thursday claims.

Actions the agency took with Biogen, maker of Aduhelm, "raise serious concerns about FDA's lapses in protocol," th...

Living in an area with easy access to parks and rivers appears to slow the progression of devastating neurological diseases, such as Alzheimer's and Parkinson's.

That's the conclusion of a new study based on more than a decade and a half tracking disease risk among ...

Researchers are studying whether deep brain stimulation could help people with Alzheimer's hold on to their memory longer, and now a new finding may help refine the approach.

Deep brain stimulation (DBS) is an established treatment for several medical conditions, including epilepsy, Parkinson's disease and obsessive-compulsive disorder. It involves implanting electrodes in certain areas o...

Groups of whales, dolphins and porpoises are regularly stranded in shallow waters around the coasts of the United Kingdom.

Researchers wanted to understand why, so they studied the brains of 22 toothed whales — or "odontocetes" — that were stranded in Scottish coastal waters.

The study includ...

Those who have dementia can find the holiday season disorienting, but their loved ones can help.

"The holiday season can be both joyful and stressful for all of us, especially individuals living with a dementia-related illness," said Jennifer Reeder, director of educational and social se...

Older adults who harbor more vitamin D in their brains may stay mentally sharper, a new study suggests.

Researchers found that when older adults had higher levels of vitamin D in their brain tissue, they tended to perform better on standard tests of memory and thinking. They were also less likely to have dementia or milder cognitive impairments.

Experts stressed that
