SOLID EVIDENCE THAT PHYSICAL ACTIVITY IS PROTECTIVE
Two large studies found that low levels of physical activity may affect brain volume and dementia risk. According to the studies, physical activity particularly affected the size of the hippocampus, a region of the brain that controls short-term memory. The inference is that regular exercise could help seniors maintain or increase their brain volume, and reduce the risk for dementia. Doctor’s verdict Physical activity reduces the risk for high blood pressure and cholesterol, and stroke, which are associated with greater risk for Alzheimer’s. If I could give only one piece of advice to middle-aged and elderly people with or without memory trouble, it would be to get 30 minutes of brisk exercise at least three times a week, and preferably every day. Also try to schedule strength-training sessions at least three times a week.
