About Alzheimer's Disease: Risk Factors & Prevention


We can’t control some risk factors for Alzheimer's disease such as age and genetic profile. But scientists are studying a number of other factors that could make a difference. Research suggests that certain lifestyle factors, such as a nutritious diet, exercise, social engagement, and mentally stimulating pursuits, might help to reduce the risk of cognitive decline and Alzheimer's disease. Scientists are investigating the associations between cognitive decline and heart disease, high blood pressure, diabetes, and obesity. Understanding these relationships and testing them in clinical trials will help us understand whether reducing the risk factors for these diseases may help with Alzheimer's as well.
