Sleep Disturbance Correlates with Cognitive Impairment Partly via Plasma p-Tau217: ADNI Cross-Sectional Evidence and P301L Mouse Mechanistic Observations

Cross-sectional study of 230 peopleMechanisms

Abstract

How sleep disturbances link to cognitive decline in Alzheimer's disease (AD) via tau pathology is unclear. We explored whether sleep dysfunction worsens cognitive deficits by elevating plasma phosphorylated tau217 (p-Tau217).
