Evidence is mounting that exercise prevents Alzheimer's as well as other types of senile dementia. In a recent study, healthy seniors exercising for fifteen minutes, three times a week, lowered their Alzheimer's risk by as much as 30 percent.
Reports USA Today, quoting Eric Larson, the study's lead researcher:
"The study, published today in the Annals of Internal Medicine, suggests that even a short, brisk walk every day might ward off the disease.
"'We don't know if exercise makes the disease go away,' Larson says, and the study doesn't provide direct proof that exercise will ward off dementia. Still, 'this is the best evidence you're going to get short of a clinical trial,' Larson says. To get hard proof, researchers will need to assign people to an exercise group or a control group and then keep track of them for many years."
