Research designed to discover strategies to delay onset and progression of Alzheimer's disease (AD) and dementia in general is ongoing world wide. Regular physical exercise is an important element in overall health promotion and might also be an effective strategy to delay onset of dementia. A growing body of evidence suggests that regular exercise is associated with a reduced risk for dementia and AD. Our recent studies showed that regular exercise was associated with 30-40% risk reduction in dementia and AD. Older persons with poor physical function were at higher risk of dementia and AD and had an increased rate of decline in cognitive function. The risk reduction by exercise was greater in persons at lower levels of physical function compared with persons at higher levels of physical function. The findings suggest that exercise, by improving and maintaining physical function, might benefit cognitive function through a connection between the two.
