Researchers in New York followed hundreds of people in their late 70s and 80s to see which pastimes went with a sharper old age. Among the physical activities, one stood alone, and it wasn't walking.
The Bronx Aging Study, run from the Albert Einstein College of Medicine, enrolled 469 people over 75 who had no dementia at the start. Each reported how often they did a long list of leisure activities. Over a median of about five years, 124 developed dementia. Joe Verghese and colleagues published the analysis in the New England Journal of Medicine in 2003.
Overall physical activity showed no link with dementia risk. The team checked walking, swimming, cycling, group exercise, climbing stairs and housework one by one, and none reached statistical significance.
Dancing was the exception. People who danced several times a week had about a quarter of the dementia risk of those who rarely danced. That was after adjusting for age, s*x, education, chronic illness, baseline thinking scores and the other activities people did.
