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.

And the more hot flashes a woman experiences during sleep, the greater her risk for developing Alzheimer’s disease, the most common type o...

Many older adults are savvy about telephone scams, but a sizable minority remain vulnerable, a new study suggests.

Researchers found that when they simulated a "government impersonation" scam -- contacting seniors and pretending to be federal employees -- over two-thirds knew how to handle the situation: They ignored it.

The rest, however, "engaged" with the "scammer." They either c...

Perhaps succumbing to fraudsters or facing mounting bills, older Americans begin losing wealth in the years preceding a definitive dementia diagnosis, new research shows.

For example, the median household net worth of the seniors in the study dropped by more than half in the eight years before they were diagnosed with dementia, but dipped much less for folks who retained their mental capa...

Bolstering the notion that a strong body equals a strong mind, new research indicates that the more inactive seniors are, the higher their risk for dementia.

The finding stems from a look at the onset of dementia among nearly 50,000 Brits.

All were at least 60 years old when information about typical daily activity routines was entered into the UK Biobank database at some point betw...

Therapies based on a hormone people make while exercising may be the next frontier in treating Alzheimer’s disease, according to a new study.

Researchers have found that the exercise-induced hormone irisin may reduce both the plaque and the tau tangles characteristic of the disease.

Before this, this same team developed the first 3D human cell culture models of Alzheimer’s disea...

Your thinking and memory skills may take a hit decades after recovering from a concussion, a new study indicates.

Scientists who studied male twins, from an average age of 67, found that earlier concussions were tied to lower scores on tests of thinking and memory. These men also had a more rapid decline in their cognitive skills — skills needed for reasoning and the acquisition o...

THURSDAY, Sept. 7, 2023 (HealthDay News) – Game show host Bob Barker died in late August from Alzheimer’s disease.

The longtime host of “The Price Is Right” died at age 99 of the memory-robbing condition, his death certificate now shows, NBC News reported.

Barker died...

Older people who take adult education classes may lower their risk for dementia, including Alzheimer’s disease, Japanese research suggests.

Middle-aged folks and older people in adult education classes had a 19% lower risk of developing dementia within five years, the researchers found.

"We also found that nonverbal reasoning performance was well preserved in the adults taking edu...

An estimated 26 million Americans 50 and older live alone, and researchers estimate that more than 4 million have dementia or cognitive impairment.

That means a large number of older Americans are at risk for medication mix-ups, unsafe driving, wandering and missing important medical appointments. And, a new study warns, the U.S. health care system is ill-equipped to address the needs of ...

Certain adult vaccines, including shingles and pneumonia shots, may also help seniors fight off Alzheimer's disease, new research reveals.

Prior vaccination with the shingles vaccine, pneumococcus vaccine or the tetanus and diphtheria shot, with or without an added pertussis vaccine, are associated with a 25% to 30% reduced risk of Alzheimer’s disease, according to researchers from...

Two recently approved treatments offer newfound hope for patients in the early stages of Alzheimer’s disease, but most people who could benefit will likely be deemed ineligible, a new study finds.

Alzheimer's affects about 6.7 million Americans age 65 and older. But only about 8% to 17% of older adults with early signs of the disease meet the eligibility criteria as determined by ...

People who daily breathe in air pollution, particularly from wildfires or agricultural sources, might need to add a heightened risk of dementia to their list of health concerns.

New research looked at the potential effects of particle pollution on dementia, finding an association even ...

Older adults who use certain heartburn medications for years may have a heightened risk of developing dementia, a new study suggests.

The study, published Aug. 9 in the journal Neurology, is the latest to point to potential hazards from prolonged use of medications called proton pump inhibitors, or PPIs. They include such well-known brands as Nexium, Prevacid and Prilosec, and th...

Black Americans are less likely to be seen at a memory clinic than their white peers. So too are folks from neighborhoods that are poor and lack educational and job opportunities, according to a new study.

That could mean later diagnosis and treatment for dementias like Alzheimer's disease.

The research, published online Aug. 2 in Neurology, involved data from more than 4...

People who carry a gene that's associated with Alzheimer's disease may lose their sense of smell long before memory and thinking problems occur, a new study suggests.

This early sign of potential dementia is not seen in people who don't carry this gene, called APOE e4, researchers report July 26 in the journal Neurology.

"Testing a person's ability to detect odors may be a...

Getting older adults who are failing mentally to relinquish their car keys can be challenging. But those conversations are necessary, said researchers who found a majority of adults with cognitive impairment still get behind the wheel.

Michigan Medicine researchers studied this issue in a South Texas community. They found that more than 600 adults over age 65 in Nueces County had cognitiv...

Emergency rooms can be a frightening place for people suffering from dementia, yet each year 1.4 million Americans with Alzheimer's or other dementias wind up in crowded, noisy ERs, a new study finds.

Dementia is responsible for nearly 7% of all ER visits for those older than 65, often because of accidents or mental health crises, researchers determined.

"While dementia is thought o...

Many people turn to probiotics for their digestive woes, but a preliminary study suggests that what's good for gut may also be good for the aging brain.

The study involved older adults with mild cognitive impairment, where memory and other thinking skills are starting to slide but people can still carry out their daily tasks. Researchers found that when those individuals took a particular...

Breakthrough new drugs that clear amyloid beta plaques from the brain are shaking up the field of Alzheimer's disease research.

The fact that patients' mental deterioration slows when they're on anti-amyloid drugs is solid proof that abnormal amyloid proteins are one of the culprits behind Alzheimer's, essentially ending decades of debate over the so-called “amyloid hypothesis.”

People looking to stay mentally sharp as they age might want to swap out margarine for olive oil, a preliminary study suggests.

The study, of more than 90,000 U.S. health professionals, found that olive oil lovers were less likely to die of dementia over the next three decades.

Compared with their counterparts who rarely used olive oil, those who consumed more than a half-tablespoon...

It's difficult to fully predict who will develop Alzheimer's disease in advance. Now, a new study suggests that certain markers in the blood may occur 10 to 20 years before the start of symptoms and could help doctors determine who is at high risk for dementia.

For the study, researchers analyzed 4,800-plus proteins in the blood of more than 10,000 middle-aged people (aged 45-65) ove...

As older people start to lose some of their mental abilities, regular exercise might slow the progression to dementia, a new study indicates.

With five months of physical activity, the mental ability of seniors with so-called mild cognitive impairment improved significantly, researchers in Canada report.

They also found that computerized training to improve memory added to the benef...

Many retirees opt to volunteer as a way to help others, but new research suggests this act can also benefit volunteers' brain health.

Volunteering later in life may provide protection for the brain from both cognitive (mental) decline and dementia, according to researchers. Their findings were presented this week at the Alzheimer's Association International Conference, in Amsterdam, in th...

Most older adults think that screening for dementia is a good idea, according to a new poll on aging. But few actually take that step.

Only about 20% of those aged 65 to 80 had a screening test in the past year to see if their memory and thinking abilities have started to decline, according to the University of Michigan's National Poll on Healthy Aging.

“As many as half of Am...

Researchers around the world are working to tease out the mechanisms behind Alzheimer's disease and other forms of dementia. Now, a new study points to so-called systemic inflammation.

British researchers found that inflammation -- activation of the body's innate immune system -- is associated with a small but statistically significant later risk of dementia. They reported their findings...

Chronic constipation may not only be an indicator of gut health, but a potential warning sign of thinking declines, a preliminary study suggests.

Researchers found that among more than 110,000 middle-aged and older U.S. adults, those who were chronically constipated -- fewer than three bowel movements a week -- also showed signs of an "older" brain.

Compared with their counterparts ...

A definitive diagnosis of Alzheimer's disease now requires a series of complicated and expensive imaging scans that look for abnormal protein plaques and tangles in the brain.

But in the near future, detecting signs of Alzheimer's could be as simple as taking a finger prick blood test.

Researchers detected key Alzheimer's-related biomarkers in dried blood samples drawn from a finger...

Older adults who begin using opioid painkillers after a dementia diagnosis have a significantly greater risk of death — about 11-fold within the first two weeks, according to new research.

The risk of death continued beyond two weeks, but at a lower rate, said researchers in Denmark. They found a doubled death risk within 90 days of opioid initiation, and said doctors must seriousl...

If you're hard of hearing and at higher risk for dementia, hearing aids could be a win-win.

New research, published July 18 in The Lancet, finds hearing aids might reduce thinking declines in older adults --but only in those at higher risk of dementia.

"Th...

A new study offers the first-ever county-level estimates of Alzheimer's disease in the United States.

It shows that the East and Southeast have the highest prevalence of Alzheimer's dementia, which researchers said may owe in part to the higher percentages of older people, and Black and Hispanic residents in those regions.
