Early-onset forms of Alzheimer disease (AD) have been associated with pathogenic variants in the APP, PSEN1, and PSEN2 genes. Mutations in presenilin-1 (PSEN1) account for the majority of cases of autosomal dominant AD. Numerous phenotypes have been associated with PSEN1-pathogenic variants, including cerebellar ataxia and spastic paraplegia. Here, we describe a patient with early-onset AD presenting with extrapyramidal symptoms and supranuclear gaze palsy, mimicking progressive supranuclear palsy.
