The relationship between sex and brain volume in a diverse sample of older adults differs by age group

Abstract

Background: It is unclear if sex differences in aging‐ and dementia‐related neurodegeneration present in the same manner across the age spectrum. Method: Analyses utilized data from three harmonized cohorts of racially and ethnically diverse older adults who completed a 3T MRI ( N = 838; 346 male, 492 female).
