Physical Activity and Trajectories of Cognitive Change in Community-Dwelling Older Adults: The Rancho Bernardo Study.

ABSTRACT:

Background

Although physical activity has been associated with better cognitive function and reduced dementia risk, its association with cognitive decline in normal aging remains uncertain.

Objective

To determine whether physical activity in youth and older age are associated with age-related cognitive change.

Methods
