title: Physical activity and dementia: The need for prevention trials.
abstract: Dementia is a common and debilitating disease that will increase dramatically for the next 50 years unless a prevention or treatment is identified. This review summarizes the evidence that physical activity is associated with a reduced risk of dementia in older adults and recommends that prevention trials be performed to determine whether this association is causal.
