Poor Midlife Fitness Tied to Later Dementia


How fit you are may predict your dementia risk. Nearly 3,600 men and women were asked to rate their fitness at midlife (an average age of 50) and then twice more over the next 30 years. Researchers tested participants’ cognitive function and collected data on dementia diagnoses. People who reported poor physical fitness at midlife were four times as likely to develop dementia as those who had good fitness at middle age. The link between poor midlife fitness and later dementia was especially strong in those with chronic conditions such as cardiovascular disease and rheumatoid arthritis. A decline in fitness after midlife also was associated with a greater dementia risk.
