Sex differences in Alzheimer's disease and common neuropathologies of aging.


ABSTRACT: Alzheimer's dementia is significantly more common in women than in men. However, few pathological studies have addressed sex difference in Alzheimer's disease (AD) and other brain pathologies. We leveraged postmortem data from 1453 persons who participated in one of two longitudinal community-based studies of older adults, the Religious Orders Study and the Rush Memory and Aging Project. Postmortem examination identified AD pathologies, neocortical Lewy bodies, DNA-binding protein 43 (TDP-43), hippocampal sclerosis, gross and micro infarcts, atherosclerosis, arteriolosclerosis, and cerebral amyloid angiopathy. Linear and logistic regressions examined the association of sex with each of the pathologic measures. Two-thirds of subjects were women (n?=?971; 67%), with a mean age at death of 89.8 (SD?=?6.6) years in women and 87.3 (SD?=?6.6) in men. Adjusted for age and education, women had higher levels on a global measure of AD pathology (estimate?=?0.102, SE?=?0.022, p?
