Medial temporal lobe subregional atrophy patterns in early‐ and late‐onset amnestic Alzheimer’s disease

The medial temporal lobe (MTL) is hypothesized to be relatively spared in early‐onset compared to late‐onset Alzheimer’s disease (AD). However, detailed examination of MTL subfields comparing amnestic early‐ and late‐onset AD is lacking. We investigate MTL subfield atrophy patterns in individuals with amnestic early‐ and late‐onset cognitive impairment (EOCI and LOCI).
