Dementia patients may develop distinct speech and reading problems depending on their native language, a new study finds.
The study included 20 English-speaking and 18 Italian-speaking patients with primary progressive aphasia (PPA), a neurodegenerative disorder that affects language areas in the brain. It is often associated with dementia.
Poor sleep has been linked to the development of dementia and Alzheimer's disease, and now a new study suggests a possible reason why.
A small group of young, healthy men deprived of just one night of sleep had higher blood levels of tau protein than when they had a full and uninterrupted night of rest, researchers reported in a study published online Jan. 8 in Neurology.
Obesity in middle age is associated with an increased risk of dementia later in life, according to a study of more than 1 million women in the United Kingdom.
Those who were obese in their mid-50s had 21% greater risk of being diagnosed with dementia 15 or more years later, compared with women who had a healthy weight, a team of British and international researchers found.
Cross-country skiing may be good for your brain, a new study suggests.
Previous research found that participants of the Vasaloppet, a popular long-distance, cross-country skiing race in Sweden, have a lower risk of heart attack, but potential brain benefits have been unclear.
This new research compared the brain health of about 200,000 who took part in the Vasaloppet between...
Playing cards and board games like chess, bingo and Scrabble might be the mental workout you need to keep your wits as you age, Scottish researchers suggest.
People in their 70s who regularly play board games score higher on tests of memory and thinking skills than those who don't. And 70-somethings who step up their game-playing are more likely to maintai...
Air pollution may trigger Alzheimer's-like brain changes and speed memory decline in older adults, a new study suggests.
Previous research has implied that exposure to fine particle air pollution increases the risk of Alzheimer's disease and other types of dementia, but it wasn't clear how this type of pollution affects the brain and memory.
Many Americans believe they are likely to develop dementia -- and they often turn to unproven ways to try to better their odds, a new study suggests.
In a survey, researchers found that almost half of Americans in their 50s and 60s believed they were at least "somewhat likely" to develop dementia. Yet few -- 5% -- said they had talked to their doctor about ways to lower their risk...
A commonly prescribed muscle relaxant known as baclofen can leave older kidney patients so disoriented that they land in the hospital, a new study warns.
"It can present with acute stroke-like symptoms, even though it's not a stroke," said senior researcher Dr. Amit Garg, a professor of nephrology at Western University in Ontario, Canada. "It can present wi...
Most people with Down syndrome have dementia by age 55, a new study shows.
People with Down syndrome are born with an extra copy of chromosome 21, which often results in developmental disabilities. Surviving to middle age used to be rare, with many dying young due to heart problems associated with the syndrome, the researchers noted.
Could one woman's rare genetic mutation one day have a global impact on dementia risk?
It's possible, say investigators who report on a potentially groundbreaking case of a woman whose genetic mutation staved off dementia for decades, even though her brain had already been damaged by Alzheimer's disease.
While most Alzheimer's cases are not driven by genetic predispo...
If you were good with words and puzzles at age 8, you're likely to fare well on tests of mental acuity at age 70, too.
That's among the findings of a new study that followed the thinking abilities of a group of Britons born in the 1940s. Researchers found that their performance on standard cognitive tests at age 8 predicted their performance around age 70. People who scored in the top...
When a loved one shows signs of dementia, sometimes a head injury is the cause and MRI scans can help prevent a misdiagnosis of Alzheimer's, researchers report.
As many as 21% of older adults with dementia may be misdiagnosed with Alzheimer's disease, a previous study found. Up to 40% of dementias are caused by conditions other than Alzheimer's disease, according to the Alzhei...
Dealing with the agitation, anxiety and aggression that often come with dementia is one of the most challenging aspects of caring for someone with this brain disorder. But new research suggests that massage and other non-drug treatments may be more effective than medications.
Even just taking people with dementia outdoors can help, said study author Dr. Jennifer Watt, a geriatrician ...
There are a number of things you can do to reduce your risk of Alzheimer's disease, according to an expert.
"People think Alzheimer's is an entirely genetic disorder, but most often, it's not," said Dr. Charles Duffy, a neurologist at Penn State Health Milton S. Hershey Medical Center in Hershey, Pa. "The two biggest risk factors for developing Alzheimer's are a person's age and prior...
Could a pacemaker for the brain improve the memories of people with dementia or Alzheimer's disease?
New research suggests it might be possible one day: Electrical stimulation directed at key memory regions of the brain created intense flashbacks in some Alzheimer's patients, including sensations of emotions, smells, taste and temperature.
If you often find yourself dosing off during the day, new research suggests it might be an early warning sign that you have Alzheimer's disease.
Areas of the brain that keep you awake during the day are damaged in the early stages of the memory-robbing disease, which is why people with Alzheimer's may nap excessively long before they start to struggle with forgetting things, the stu...
Repeated exposure to head trauma during play often causes significant brain damage, researchers report. That damage then gives rise to neurological disease, which then boosts the risk for dementia by the time players reach middle-age and beyond.
Keeping your brain active as you age, whether it be working on a computer, playing games or being socially involved, might ward off memory loss, a new study suggests.
Losing memory as you age is a sign of mild cognitive impairment, which can be a gateway to dementia or Alzheimer's disease. But using your brain can help keep it sharp, and it's never too late to start reaping the benef...
Every college student misplaces keys or forgets an appointment from time to time. Usually it's no big deal. But a new study warns that when young people with a family history of Alzheimer's disease have memory lapses, it could be an early sign of something serious.
That's the concern raised by a new memory test taken by nearly 60,000 men and women between the ages of 18 and 85.
Many aging Americans have the common heart rhythm disorder known as atrial fibrillation, or "a-fib." Now comes the sobering news that it might raise their odds for dementia.
The Korean study couldn't prove cause and effect, but researchers noted that the link between a-fib and dementia was found even among people who hadn't suffered a stroke. A-fib is a known and potent risk factor fo...
If someone you know is struggling to keep track of their finances as they age, early dementia might be the culprit.
That's the conclusion of researchers who tested 243 adults, aged 55 to 90, on their financial skills and performed brain scans to assess the buildup of beta-amyloid plaques, which are associated with Alzheimer's disease.
Liquid detergent packets or "pods" continue to poison kids years after their makers volunteered to make them safer.
Such poisonings fell just 18% between 2015 and 2017, a new study reports. From 2012 to 2017, poison control centers fielded nearly 73,000 calls about poisoning from these pods. That's about one call every 42 minutes, and almost 92% involved kids under 6.
When older adults fall prey to scam artists, it might in some cases be an early warning of Alzheimer's disease, a new study suggests.
The study of 935 older adults found that those who appeared susceptible to scams were at higher risk of mental decline over the next six years. Compared with their more skeptical peers, they were 47% more likely to develop mild cognitive impairment ...
Many older adults, including those who are mentally impaired, don't lock up their guns and ammo, University of Washington researchers report.
Almost 39% of the more than 4,400 seniors they surveyed in Washington state said they had a firearm in their home. Nearly a quarter said they keep at least one gun loaded and unlocked. Fewer than a third said they keep all firearms locked u...
A new study suggests that the fewer menstrual periods a woman has in her lifetime, the higher her risk of dementia -- though the reasons, for now, are unclear.
The study was based on close to 16,000 women. It found that those who started having periods at age 16 or later were more likely to develop dementia than women who started menstruating at a more typical age.
