To determine the cross-sectional association between cerebral amyloid-beta (Aβ) deposition and gait. ⋯ PiB-PET SUVR across ROIs, independent of general measures of AD-associated neurodegeneration, is associated with poorer performance on multiple gait parameters among cognitively normal women, aged 50 to 69 years. Longitudinal studies are needed to determine whether Aβ predicts gait decline in both women and men.
