While we do not yet have a cure for Alzheimer's, there are some things you can do to reduce your risk for the disease.
Recent research suggests that a combination of physical activity and the "Mediterranean diet" might delay the onset of Alzheimer's by as much as seven years, while also providing other health benefits.
The benefit of physical activity in maintaining brain health has long been acknowledged. Essentially, everything that is good for your heart — like cardiovascular exercise — is good for your brain.
However, some people are put off of exercise because they think they won't be able to exercise hard enough or long enough to make a difference. In a study of 1,880 people conducted at Columbia University, researchers found that as little as 20 minutes daily of moderate walking or similar exercise contributed to brain health.
