Enhanced Sensitivity to Elevated Plasma p ‐Tau 217 with Proper Name Delayed Recall in the Preclinical Alzheimer's Cognitive Composite

Abstract

Background: The Preclinical Alzheimer's Cognitive Composite (PACC) is a vital tool for detecting early Alzheimer's disease (AD)‐related cognitive changes. Plasma p ‐Tau217, a highly sensitive AD blood‐biomarker, reflects abnormal brain amyloid and tau accumulation.
