Researchers observed residents and staff at four assisted living communities over the course of a year.

They found that a few factors stood out as key to keeping residents with dementia socially and mentally...

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 ...

Doctors are seeing such cases around the world: About a third of COVID-19 patients go on to develop "long-haul" neurological or psychiatric conditions months after being infected, new research shows.

The findings suggest a link between COVID-19 and a higher risk for later mental health and neurological disorders, researchers report.

The new analysis of data from more than 236,000 ...

Caring for a loved one with Alzheimer's disease can be mentally and physically exhausting, so you should take steps to manage and reduce stress, according to the Alzheimer's Foundation of America.

Middle-aged folks who feel persistently lonely appear to have a nearly doubled risk of developing dementia or Alzheimer's disease, a new study reports.

If you take steps to counter your loneliness, however, you might actually reduce your dementia risk, the researchers found.

Dementia risk rose 91% in those who reported feelings of loneliness that persisted across two separate health...

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...

Exercise, mental stimulation and massage are among the drug-free therapies that are as good or better than medication in treating depression in dementia patients, researchers say.

They reviewed 256 studies that included a total of more than 28,000 people with dementia with or without major depression.

Medications alone were no more effective than usual care in treating depression in...

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.

"Risk...

If you're a 20-something who wants to stay sharp, listen up: A new study suggests poor health habits now may increase your risk of mental decline later in life.

Its authors say young adulthood may be the most critical time for adopting a healthy lifestyle in order to keep your brain sharp when you're older.

That's the upshot of an analysis of data from about 15,000 adults who were p...

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.

Donanemab diss...

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...

Many older adults with dementia are prescribed dangerous combinations of drugs that raise their risk of overdose, falls and further mental deterioration, a new study finds.

About 1 in 7 people with dementia living outside of nursing homes are taking three or more drugs that act on their brain and nervous system, researchers reported.

The most troubling combinations involved opi...

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...

People with Alzheimer's disease often have a history of depression or anxiety, which might mean an earlier emergence of memory and thinking problems, a preliminary study suggests.

Researchers found that of 1,500 Alzheimer's patients at their center, 43% had a history of depression, while almost one-third had a history of anxiety disorders.

Those patients also tended to be diagnosed ...

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.

"Not all ...

Researchers may have uncovered a key reason some people remain sharp as a tack into their 80s and 90s: Their brains resist the buildup of certain proteins that mark Alzheimer's disease.

The study focused on what scientists have dubbed "super agers" -- a select group of older folks who have the memory performance of people decades younger.

Compared with older people who had average b...

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.

Their risks were double that of older people...

"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.

That increased risk was independent of age, a...

As Tony Bennett releases what may well be his last album, his family has disclosed that the 1950s crooner who became popular with younger audiences decades later has Alzheimer's disease.

His wife, Susan, made the announcement in an interview published in AARP magazine. She said Bennett, 94, is content and happy and took the diagnosis calmly.

"But that's because he already d...

Enlarged spaces in the brain that fill with fluid around small blood vessels may be a harbinger of impending dementia, a new Australian study suggests.

Typically, these so-called perivascular spaces help clear waste and toxins from the brain and might be linked with changes in the aging brain, researchers say.

"Dilated perivascular spaces, which are a common MRI finding, especi...

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.

"W...

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.

Patients with demen...

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.

"As many as 90% o...

Physical activity is known to help prevent dementia and disease, but it's possible that the kind you do makes a difference.

A new study found that hard physical work not only doesn't lower the risk of dementia, it increases the risk of developing the disease.

Researchers found that people who do hard physical work have a 55 percent higher risk of developing dementia than th...

Experts in healthy aging often cite the importance of leisure activities -- hanging out with friends, playing games, taking classes -- in maintaining your brain health as you grow older.

But a new study calls into question whether those enjoyable pursuits actually protect you against dementia.

Researchers found no link between middle-aged folks taking part in leisure activities and ...

Older adults who get together with friends, volunteer or go to classes have healthier brains, which could help them ward off dementia, according to a new study.

Researchers who used brain imaging to examine brain areas involved in mental decline found that greater social engagement made a difference in brain health.

Being socially engaged -- even moderately -- with at least one ...

Offering fresh insight into the deep-seated roots of dementia, new research finds that diminished blood flow to the brain is tied to buildup a protein long associated with Alzheimer's disease.

Called "tau," high levels of the protein are "one of the hallmark pathologies that define Alzheimer's disease in the brain," explained study author Judy Pa. She is an associate professor of neur...

Older adults who aren't interested or enthusiastic about their usual activities may have a higher risk of developing dementia, new research suggests.

In catheter ab...

A common type 2 diabetes drug called metformin may have an unexpected, but positive, side effect: New research suggests that people taking the drug appear to have significantly slower declines in thinking and memory as they age.

"Our six-year study of older Australians with type 2 diabetes has uncovered a link between metformin use and slower cognitive [mental] decline and lower deme...

In older people a fall can sometimes be a sign of oncoming Alzheimer's disease, even in the absence of mental issues, new research suggests.

Although falls are common among older people, in some cases they can be a sign of hidden mental problems that can lead to dementia, according to researchers at Washington University School of Medicine in St. Louis.

Older people who hav...

Everyone needs sleep, but too little or too much of it might contribute to declines in thinking, a new study suggests.

Too little sleep was defined as four or fewer hours a night, while too much was deemed 10 or more hours a night. The ideal amount? Seven hours a night.

"Cognitive function should be monitored in individuals with insufficient or excessive sleep," said study ...

And with care often lasting for y...

A group of widely used medications might speed up older adults' mental decline -- especially if they are at increased risk of dementia, a new study hints.

The medications in question are called anticholinergics, and they are used to treat a diverse range of conditions -- from allergies, motion sickness and overactive bladder to high blood pressure, depression and Parkinson's disease.<...

Feeling woozy when you stand up may be a sign of an increased risk of developing dementia, a new study suggests.

Doctors call this feeling "orthostatic hypotension," and it occurs when there's a sudden drop in blood pressure as you stand, explained a team of researchers from the University of California, San Francisco (UCSF).

The researchers found a connection between orth...

Aging baby boomers may not be as mentally sharp as their parents were, a new study suggests -- raising questions about what the pattern could mean for future dementia rates.

Looking at two decades' worth of data on U.S. adults, the study found generational differences in tests of cognitive function. That refers to essential mental abilities such as remembering, reasoning and problem-s...

Need fresh motivation to lose some weight? New research suggests that young adults who are overweight or obese face a higher risk for dementia in their golden years.

For the study, the researchers looked at just over 5,100 older adults who were involved in two long-term studies. The investigators found that women who were overweight between 20 and 49 years of age had nearly twice the ...

A new blood test offers hope that doctors may soon be able to diagnose Alzheimer's disease with astonishing accuracy.

A study led by Swedish researchers found the test did more than differentiate between Alzheimer's and other types of dementia. It also spotted signs of Alzheimer's two decades before symptoms appeared in people who were genetically predisposed to develop the degenerati...

First responders to the 9/11 terrorist attacks appear to be at increased risk for Alzheimer's disease and dementia, new research suggests.
