Discrimination tasks increase the value of plasma p ‐tau217 to predict presymptomatic Alzheimer's disease

Abstract

Background: AD can be diagnosed using amyloid (Aβ) and tau‐PET imaging. These techniques are expensive and invasive, making them hardly practical for screening in clinically unimpaired (CU) populations. Research is therefore focused on developing more affordable methods to detect pre‐symptomatic AD pathology.
