Plasma p‐tau217 detects Alzheimer's disease co‐pathology in cerebral amyloid angiopathy: Comparison to CSF biomarkers in the ANGMAR cohort
Cerebral amyloid angiopathy (CAA) frequently co‐occurs with Alzheimer's disease (AD), generating mixed vascular–neurodegenerative phenotypes. Plasma phosphorylated tau (p‐tau)217 is a robust biomarker of AD, but its performance in CAA remains unclear.
