THURSDAY, Feb. 25, 2021 (HealthDay News) -- The ravages of Alzheimer's may strike later in women than men, but once it takes hold women tend to deteriorate far faster than men, according to a new study.

Something known as cognitive reserve helps the aging brain function better for longer, and researchers report that women appear to have more of it than men. But once the...

THURSDAY, Feb. 25, 2021 (HealthDay News) -- 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 anxie...

TUESDAY, Feb. 23, 2021 (HealthDay News) -- 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 decad...

It can begin with the occasional missed bill payment. An inability to remember names. Telling the same story repeatedly. There may be personality changes or mood swings. Confusion. Over time, it's as if the person who once was slowly disappears.

Dementia. As the population ages, a growing number of families face this debilitating condition, which can be both emotionally and financially ex...

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 hyperinte...


Scientists may have discovered why cold sores caused by herpes simplex virus (HSV) are triggered by stress, illness and sunburn.

The finding could lead to new ways to prevent recurring cold sores and herpes-related eye disease, U.S. and British researchers say.

More than half of Americans are infected with herpes simplex virus. It is spread throu...

"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...

Older men whose blood pressure rises at night may be at increased risk for Alzheimer's disease, a new study suggests.

Blood pressure changes over 24 hours. It typically goes up during the day and dips at nighttime. But some people have an opposite pattern, which is called reverse dipping.

"The night is a critical period for brain health. For example, in animals, it has previously be...

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 findi...

All Alzheimer's disease patients and their family caregivers should be vaccinated against COVID-19, the Alzheimer's Foundation of America says.

"Getting vaccinated is one of the most important steps families affected by Alzheimer's disease can take to protect themselves and their loved ones," said Dr. J. Wesson Ashford, chair of the foundation's medical, scientific and memory screening ad...

A rare brain disease that causes loss of language skills doesn't lead to memory loss, a new study finds.

The condition is called primary progressive aphasia and about 40% of people who have it have underlying Alzheimer's disease, according to researchers. Their study was published online Jan. 13 in the journal Neurology.

"While we knew that the memories of people with prima...

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 pro...

The coronavirus pandemic makes the holidays even more difficult for caregivers of loved ones with Alzheimer's disease and other types of dementia, an expert says.

"Even in the best of times, holidays can be a mixed bag for families who are caring for a loved one with an age-related illness that causes physical and mental changes. Focus on family togetherness and joy," said Mary Catherine ...

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...

Older adults with memory problems may progress to Alzheimer's more quickly if they are also suffering from anxiety symptoms, a preliminary study suggests.

It's common for people with Alzheimer's disease to have mood symptoms, including anxiety and depression. And some research has suggested those symptoms can, in older people, act as early indicators of the dementia process.

The new...

Pollutants in the air -- fine particulates that are 30 times smaller than the width of a strand of hair -- may be damaging older women's brains.

In a new study, researchers linked breathing in high levels of this polluted air to shrinkage in areas of the brain that are vulnerable to Alzheimer's disease.

"Fine-particle pollution is kind of like a cocktail. There are a lot of differen...

Being positive may help protect your memory as you age, a new study indicates.

Researchers analyzed data from almost 1,000 middle-aged and older U.S. adults who took part in a national study. The upshot: Being upbeat pays dividends.

Participants were assessed three times: between 1995 and 1996, 2004 and 2006, and 2013 and 2014. At each assessment, the participants describe...

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 ...

If you're a senior who can't smell onions, smoke, chocolate or natural gas, it's time to see your doctor.

Seniors who lose their sense of smell -- which doctors call olfactory dysfunction -- have higher odds of dying from all causes within five years, new research shows. Scientists had previously found a link between olfactory dysfunction and impaired thinking and memory.

"We ...

As the air people breathe gets dirtier, their odds for serious neurological disorders such as Parkinson's disease, Alzheimer's and other dementias rises, new research shows.

The long-term study of more than 63 million older Americans can't prove cause and effect, but does show a strong association between air pollution and brain disorders. The researchers said the link was seen even a...

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...

A procedure to restore normal heart rhythm is more effective than medications in reducing dementia risk in people with the heart rhythm disorder atrial fibrillation (AF), researchers report.

Previous studies have shown that AF is associated with an increased risk of dementia. This one assessed whether catheter ablation and medications for AF reduced that risk.

In catheter ab...

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...

A genetic variant in some people may be associated with mental decline that can't be explained by deposits of two proteins linked with Alzheimer's disease, researchers say.

They said their findings could lead to new treatments for Alzheimer's.

The two proteins are amyloid β and tau. Amyloid forms into plaques and tau forms into tangles. Both are found in the brains of A...

Alzheimer's disease is more common in rural Appalachian areas of Ohio than in other rural parts of the state, new research shows.

For the study, the investigators analyzed 11 years of Medicare data, ending in 2017, and found that Alzheimer's rates were 2% to 3% higher in rural Appalachian counties than in other rural counties in Ohio.

The study, published online rece...

Add a heightened risk for depression to the list of challenges facing the caregivers of loved ones who have Alzheimer's disease.

A new study found that older adults caring for spouses newly diagnosed with Alzheimer's had a 30% increase in symptoms of depression compared to those whose spouses didn't have Alzheimer's or related dementia.

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.<...

Disturbed sleep doesn't cause Alzheimer's disease, but some sleep patterns may be more common in people who have a high genetic risk for it, a new study reports.

Those patterns include being a morning person, having shorter sleep duration and being less likely to have insomnia, according to findings published in the Aug. 19 online issue of the journal Neurology.

"We ...

As many as 3 in 4 older adults with dementia have been prescribed drugs that may pose a risk to them, researchers report.

The drugs in the study included commonly prescribed medications that can affect the brain or nervous system, such as sedatives, painkillers and antidepressants.

"There just is not a lot of evidence that these medications are helpful in people with dement...

As researchers hone in on ways to detect whether someone has a high risk of developing Alzheimer's disease before they have any symptoms, mental health professionals have worried what the psychological fallout of that knowledge might be.

But new research suggests that people can handle the truth.

In the study, seniors who didn't have any Alzheimer's symptoms underwent a sp...

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...

Among people who have the gene that carries a heightened risk for early-onset Alzheimer's disease, a new study suggests that more education might slow the development of beta-amyloid plaques in the brain.

About 1% to 6% of people with Alzheimer's disease have genes that put them at risk for early development of the disease, which can start in their 30s to 50s, the researcher...

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.

The prevalence of post-traumatic stress disorder (PTSD) and mild thinking impairments among them is well-known, and now two studies from Stony Brook University in New York have identified changes in their brains similar to those in dementia patient...

Getting vaccinated to protect against pneumonia and flu may offer an unexpected benefit -- a lower risk of Alzheimer's disease, new research suggests.

Two new studies being presented Monday at this summer's virtual Alzheimer's Association International Conference found a lower incidence of Alzheimer's in people who got flu and pneumonia vaccines. A third study underscored the importa...

Every summer seems to bring fresh warnings of toxic algae blooming in local ponds, lakes and waterways.

These toxic blooms are known to be dangerous to human and animal health, but a new study suggests they might be even more harmful than previously thought.

A single massive blue-green algae bloom in Florida's Lake Okeechobee and the Caloosahatchee River flowed into the Gulf...

Some people in their 90s stay sharp whether their brain harbors amyloid protein plaques -- a hallmark of Alzheimer's disease -- or not, but why?

That's the question researchers sought answers for among 100 people without dementia, average age 92, who were followed for up to 14 years. Their answer? A combination of genetic luck and a healthy, fulfilling lifestyle.

"The vast ...

Ten risk factors may affect your risk of developing Alzheimer's disease, a new Chinese study suggests.

Focusing on these factors could help doctors develop guidelines for preventing Alzheimer's, researchers say. The risk factors include mental activity, obesity in late life, depression, diabetes and high blood pressure.

The need is urgent: Alzheimer's is the most common fo...

Many people with dementia may have access to a gun in their home, yet few families have gotten advice from a doctor on how to handle the situation, a small new study finds.

In the United States, somewhere between 39% and 49% of older adults live in a home with firearms, the researchers said. Meanwhile, more than 5 million Americans are living with Alzheimer's disease, the most...

Getting the recommended amount of exercise could cut your risk of early death, a new study indicates.

U.S. government guidelines recommend at least 150 minutes of moderate intensity or at least 75 minutes of vigorous intensity aerobic activity a week. They also suggest adults do moderate or greater intensity muscle-strengthening exercise at least two days a week.

That effort...

The progression of Alzheimer's disease may accelerate as iron deposits build up in the brain, a new study finds, hinting at a possible role for the mineral in mental decline.

Using MRI scans of 200 older adults with and without Alzheimer's, researchers found that those with the disease generally had higher iron levels in various parts of the brain. And 17 months later, Alzheimer's pat...

Women have more Alzheimer's disease-related changes in the brain than men, and this may be linked to hormonal disruptions at menopause, researchers say.

"About two-thirds of people living with Alzheimer's are women, and the general thinking has been it's because women tend to live longer," said study author Lisa Mosconi of Weill Cornell Medicine in New York City.

"Our findin...

If you've been looking for a good reason to slim down, consider this: Being obese at midlife appears to increase your odds for dementia.

That's the takeaway from a large study just published by British researchers, and it echoes similar findings published in December.

Dorina Cadar, lead researcher on the new study, said the goal is to identify risk factors that are influence...

Caring for someone with Alzheimer's disease comes with daily challenges and disruptions, and those have only increased during the COVID-19 pandemic.

Due to the risk of infection, contact with your loved one may now be off-limits or severely restricted. Caregivers probably need to wear masks, which may be confusing to someone with Alzheimer's. And, if your loved one gets sick, how do ...

A combination of healthy habits -- such as a good diet and regular exercise -- may lower your risk of Alzheimer's disease by as much as 60%, a new study suggests.

Data from nearly 3,000 people in the United States was scored on five beneficial lifestyle factors: high-quality diet, physical activity, not smoking, brain-challenging activities, and light-to-moderate alcohol consumpti...

Social restrictions during the coronavirus pandemic can be especially hard for people who can't visit loved ones with Alzheimer's disease who are in nursing homes.

Despite an easing of restrictions, the U.S. Centers for Medicare and Medicaid Services says nursing homes shouldn't allow outside visitors until the last phase of its reopening guidelines.

"One of the hardest part...
