Biomarkers and neuropathology in posterior cortical atrophy: an international, multi‐site study

Posterior cortical atrophy (PCA) is a clinically defined syndrome characterized by impairment in higher‐order visual processing. The underlying pathology in PCA is most commonly Alzheimer’s disease (AD), but large‐scale biomarker and neuropathological studies are lacking. In this ongoing project we aim to describe demographic, clinical, biomarker and neuropathological correlates of PCA in a large‐scale international cohort.
