Minding your heart health when you're young could spare your brain from dementia decades later, new research confirms.
Chinese researchers looked at data on more than 450,000 older Britons. They found that people who'd already been in poor cardiovascular health before they reached the age of 45 had a 25% higher odds of developing dementia, compared to those with better heart heath.
Alzheimer’s patients are notoriously irritable, agitated and anxious – and researchers now think they know why.
Brain inflammation appears to influence the mood problems of Alzheimer’s patients, rather than traditional markers of the disease like amyloid beta or tau proteins, researchers report in the Nov. 27 issue of the journal
Whole grains could be the key to Black people protecting their brains against aging and dementia, a new study reports.
Black folks who ate more foods with whole grains appeared to have a slower rate of memory decline than those who ate fewer whole grains, according to findings published Nov. 23 in the journal Neurology.
Among Black people, those who ate the most whole grain...
Middle-aged folks with lots of belly fat surrounding their internal organs appear to be at higher risk for Alzheimer’s disease later in life, a new study suggests.
This hidden abdominal fat -- known as visceral fat -- is related to changes in the brain up to 15 years before the earliest symptoms of Alzheimer’s manifest, according to findings to be presented at next week’s annual mee...
Shrinkage of one of the brain's key memory centers appears to herald thinking declines, a new study finds.
The region in question is the hippocampus, a two-sided structure located roughly above each ear and embedded deep within the brain's temporal lobe. It's long been known to play a crucial role in the storage and transference of short- and long-term memory.
The ancient art of tai chi, plus a modern twist, may help older adults reverse mild declines in brain power, a new clinical trial reveals.
Researchers found that tai chi classes helped older adults improve their subtle problems with cognition (memory and thinking skills). It also helped them with a fundamental multitasking skill: walking while your attention is elsewhere.
Millions of older Americans may be unaware they have memory and thinking impairments -- mostly because their doctors aren't diagnosing them, new research suggests.
After analyzing Medicare data covering 40 million older Americans, researchers found that only a small percentage of expected cases of mild cognitive impairment (MCI) were actually diagnosed. The upshot was that more t...
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.
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...
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.
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.
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 di...
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...
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 t...
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...
Scientists have struggled for decades to come up with something that can successfully treat Alzheimer's disease, with new drugs now showing their ability to clear the amyloid plaques that are a hallmark of the memory-robbing disease.
But what if a vaccine could do the same job, or better? A new Japanese study suggests it may be possible.
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.”
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...
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.
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.
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.
Writing letters, taking classes and playing mentally stimulating games like chess in your older years could lower your risk of dementia over the next decade, a new study suggests.
Researchers in Australia found that journaling, using a computer, taking education classes and other "literacy enrichment" activities might lessen the risk of developing dementia by 11%. Playing games, car...
As extreme heat continues to blanket numerous parts of the United States, Americans with dementia may be particularly challenged.
“Triple-digit temperatures and heat indexes are especially dangerous for someone with a dementia-related illness such as Alzheimer's disease, because the effects of dementia can impair their ability to notice if they are developing heat stroke or dehydra...
