Genes That Affect Brain’s Immune Cells May Increase Risk of Alzheimer’s

Scientists identified new genes that impact the brain’s immune cells and may contribute to the risk of developing early-onset or late-onset Alzheimer’s.

Intensive blood pressure control may slow age-related brain damage

In a nationwide study, researchers used magnetic resonance imaging (MRI) to scan the brains of hundreds of participants in the National Institutes of Health’s Systolic Blood Pressure Intervention Trial (SPRINT) and found that intensively controlling a person’s blood pressure was more effective at slowing the accumulation of white matter lesions than standard treatment of high blood pressure. The results complement a previous study published by the same research group which showed that intensive treatment significantly lowered the chances that participants developed mild cognitive impairment.

How Exercise Lowers the Risk of Alzheimer’s by Changing Your Brain

More and more studies are showing how regular exercise benefits the brain, and in particular, the aging brain. What’s less clear is how exactly exercise counters the cognitive decline that comes with aging and diseases like Alzheimer’s.

Healthy lifestyle associated with lower risk of dementia independent of genetic risk, study finds

Following a healthy lifestyle is associated with a lower risk of dementia in cognitively healthy older adults at varying levels of genetic risk for Alzheimer’s disease and related dementias, according to a study published online July 14 in JAMA. Funded in part by NIA, the study is the first to examine the relationship between multiple genetic risk factors for dementia and multiple lifestyle factors.

Another Alzheimer’s study ends too soon

An Alzheimer’s disease prevention trial was stopped early for safety reasons. Learn why the study ended early and what’s next in the ongoing search for drugs to prevent and treat this disease.

How to Keep Your Brain Happy and Healthy

When you consider everything this awe-inspiring organ does for you, it's mind-blowing. But caring for it isn't always top of, well, you know. To keep your brain sharp and nimble, learn how to challenge it, what to feed it, and when to let it wander.

New Markers For Alzheimer's Disease Could Aid Diagnosis And Speed Up Drug Development

Alzheimer's disease begins altering the brain long before it affects memory and thinking.

So scientists are developing a range of tests to detect these changes in the brain, which include an increase in toxic proteins, inflammation and damage to the connections between brain cells.

Researchers Explore Why Women's Alzheimer's Risk Is Higher Than Men's

Scientists are beginning to understand why Alzheimer's disease affects more women than men and why the disease seems to progress more quickly in women's brains.

A Blood Test Can Predict Dementia. Trouble Is, There's No Cure

Nobel prizewinner Koichi Tanaka says the predictive blood test for Alzheimer’s disease he and colleagues spent almost a decade developing is a double-edged sword.
