P‐tau181 is longitudinally associated with a proxy measure of mild behavioral impairment among frail older adults: Insights from COGFRAIL
Abstract INTRODUCTION Cross‐sectional studies link Alzheimer's disease (AD) pathogenesis to mild behavioral impairment (MBI), but longitudinal evidence remains limited. We examined whether plasma phosphorylated tau (p‐tau)181 predicts progression of an MBI‐proxy over 2 years in pre‐frail and frail older adults with mil...
