Risk Factors

Napping more? That could be an early symptom of Alzheimer's, new study says

Increased, excessive napping could be an early warning of Alzheimer's disease, according to research published in August by the peer-reviewed journal Alzheimer's & Dementia.

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.

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.

More studies seek people with mild cognitive impairment

In order to get ahead of Alzheimer’s disease earlier, more and more research studies are seeking people without changes to their memory and thinking along with those with a condition known as mild cognitive impairment (MCI). The question is, how do you know if you have it?

Boost brain health with a healthy diet - not supplements

A nutritious diet is a much better way to keep your brain healthy than dietary supplements. The Global Council on Brain Health recommends people be wary of supplements and always consult their doctor before taking them. Read more about their recommendations about dietary supplements.

Leading Researcher Weighs in on Lewy Body Dementia Versus Alzheimer’s

Imagine being told you are living with Alzheimer’s disease only to discover you have been misdiagnosed and are suffering from another neurodegenerative condition. At 52 years old, Mike Belleville was diagnosed with early-onset Alzheimer’s. Several years later, he was reevaluated and learned he has Lewy body dementia (LBD), a disease many researchers believe is the second most common form of dementia, affecting an estimated 1.3 million Americans. Belleville is among a number of people who have experienced the pain of misdiagnosis and are living with what the Lewy Body Dementia Association (LBDA) calls “the most misdiagnosed form of dementia.”
