Abstract: Dementia is not just a disease of old age. Early-onset dementia affects people younger than 65 and its differential diagnosis is broader than in older people. Nevertheless, although young people are considerably more liable to develop a rare form of dementia, Alzheimer’s disease (AD) remains the most common diagnosis. The aim of this article is to report on an early-onset AD patient associated with the rare pathogenic variant PSEN1 (Leu85Pro) presenting as a possible corticobasal syndrome with asymmetric limb apraxia, parkinsonian signs, and myoclonus.
