Abstract

Spinocerebellar ataxia type 2 (SCA2) is characterized by progressive cerebellar ataxia and slow saccades. A 40-year-old woman presented with progressive gait disturbance and ataxia over 15 years. Neurologic examination revealed scanning speech, ataxia, and hyporeflexia. Brain CT showed diffuse atrophy of the cerebellum. Electronystagmography demonstrated slowed saccades with normal accuracy and delayed latency. The diagnosis of SCA2 was confirmed by the genetic test. Documentation of slow saccades may help differentiation among SCA subgroups.
