진행성 인지장애를 첫 증상으로 보인 치아적핵창백핵루이체위축증 1예

Abstract

A 50-yr-old woman presented with progressive cognitive impairment and later developed abnormal movements. Brain magnetic resonance imaging (MRI) showed diffuse atrophy of the cerebellum and brainstem and severe high signal intensities in the periventricular white matter on T2-weighted images. The genetic analysis confirmed the diagnosis of dentatorubropallidoluysian atrophy (DRPLA). DRPLA should be considered in a patient with family history who showed cognitive impairment alone for a substantial period and severe white matter involvement with diffuse atrophy on MRI.
