    One Part of Your Brain Could Point to the Mind's Decline

    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 new research was ...

    Tai Chi Might Help Seniors Counter Mild Cognitive Decline

    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.

    But ...

    7 Million Americans Have Mild Cognitive Impairment and Don't Know It

    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...

    Have Diabetes? Quitting Metformin Could Take Toll on Your Brain

    Millions of people with diabetes take the drug metformin to control their blood sugar levels.

    Meant to be taken for the long term, new research now suggests that stopping it early may up the risk of developing thinking and memory problems as patients age.

    “We found that staying on metformin prevents or delays dementia onset, and this is very encouraging,” said researcher

    High Blood Triglycerides Could Help Ward Off Dementia

    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.

    Over six years, 3% of older folks with t...

    Neighborhood Parks Could Help Your Aging Brain

    A variety of risks can make it more likely that someone develops Alzheimer's disease or other dementias.

    Short Sleepers May Be at Higher Risk for Depression

    Scientists have long wondered whether depression leads to less sleep or whether a lack of sleep triggers depression.

    A new study suggests it's the latter: Getting less than five hours of sleep a night may raise the risk of developing depressive symptoms.

    “We have this chicken or egg scenario between suboptimal sleep duration and depression, they frequently co-occur, but which come...

    Dementia Diagnosis Takes Huge Toll on a Family's Finances

    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.

    “We found a pr...

    Adults With ADHD May Face Higher Dementia Risk

    Adults with attention-deficit/hyperactivity disorder (ADHD) are nearly three times more likely to develop dementia than other adults, a new study suggests.

    Are These Pricey New Alzheimer's Drugs Worth It?

    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.”

    Olive Oil a Powerful Prescription Against Dementia

    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...

    Scientists Spot 32 Proteins That Hint at Alzheimer's Risk

    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...

    Constipation May Be a Marker for Dementia Risk

    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 ...

    Blood Prick Test for Alzheimer's Shows Promise

    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...

    New Opioid Use Raises Death Risk 11-Fold in Those With Dementia

    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...
