Abstract

Abstract The two cardinal pathologies of Alzheimer’s disease (AD) develop according to distinct anatomical trajectories. Cerebral tau-related pathology first accumulates in the mesial temporal region, while amyloid-related pathology first appears in neocortex. The eventual distributions of these pathologies reflect their anatomical origins. An implication is that the cardinal pathologies might exert preferential effects on the structurofunctional brain changes observed in AD. We investigated this hypothesis in 39 patients with dementia of the Alzheimer’s type. Interrelationships were analysed between cerebrospinal fluid (CSF) biomarkers of the cardinal pathologies, volumetric brain changes u..
