Value of plasma biomarkers to predict memory change in cognitively unimpaired individuals

Plasma levels of amyloid‐β1‐42/1‐40, phosphorylated‐tau (P‐tau) and glial fibrillary acidic protein (GFAP) can be used to predict amyloid‐β pathology in elderly cognitively unimpaired individuals, but their prognostic value in early Alzheimer’s Disease (AD) stages in the normal aging population needs further study. We aimed to investigate the value of these plasma biomarkers for predicting memory change in cognitively unimpaired individuals in a population‐based cohort.
