Effect of lifestyle activities on alzheimer disease biomarkers and cognition

A study was undertaken to investigate the association of intellectual and physical activity with biomarkers of Alzheimer disease (AD) pathophysiology and cognition in a nondemented elderly population. The biomarkers evaluated were brain Aβ load via Pittsburgh compound B (PiB)‐positron emission tomography (PET), neuronal dysfunction via 18F‐fluorodeoxyglucose (FDG)‐PET, and neurodegeneration via structural magnetic resonance imaging (MRI).
