Accelerated trajectories of cognitive decline in older adults may increase the risk of developing Alzheimer disease and related dementias (ADRD). Physical activity has potential modifying effects on these changes that could prevent or delay ADRD. This review explores the hypothesis that multiple, mutually complimentary, and interacting factors explain the positive association between exercise and the optimization of cognition in older adults.

The role of physical activity and the interplay between physiological biomarkers and psychological and lifestyle factors on cognitive aging.
