Exercise to Ward Off Dementia
To help protect against dementia, get off the couch and go for a walk. For five years, researchers tracked 1,646 Canadian men and women whose average age was 76. None had the degenerative brain disease at the start of the study. Ten percent had diabetes. The regular exercisers—most of whom walked about three times a week—were half as likely to be diagnosed with dementia as those who never exercised. The study, however, did not say how long the exercisers walked. But the findings were clear: Couch potatoes had the same elevated odds of developing dementia as people born with a gene that triples the risk of Alzheimer’s disease, the most common cause of dementia.
