High p‐Tau217 Levels Nullify Age‐related Cognitive Protection in Younger Older Adults [PDF]

Alzheimers Dement
Abstract Background Plasma p‐tau217 is pivotal for diagnosing Alzheimer's Disease (AD) and monitoring its progression, with high p‐tau217 levels associated with amyloid pathology and faster cognitive decline. While younger age is generally expected to provide protection against cognitive decline, the interaction between p‐tau217 levels and age on the ...
