Sex-Specific P-Tau217 Dynamics: Why Women Exhibit Accelerated Tau Accumulation and Cognitive Decline

By MedXY 02/20/2026

A multi-cohort study demonstrates that women with amyloid-β pathology show higher plasma p-tau217 levels and faster tau PET accumulation than men, providing a biological basis for their increased risk of rapid cognitive decline in preclinical Alzheimer’s disease.
