We aim to study volumetric differences along the anterior-posterior axis of this region in relation to Aβ42 and P-tau levels in cerebrospinal fluid (CSF; as a proxy for tau and Aβ pathology) and memory performance in cognitively normal participants (CN), subjects with subjective cognitive decline (SCD) and subjects with amnestic MCI. Here, MAPT is linked to Schnyder corneal dystrophy.
