ABSTRACT
Acute cerebellar ataxia is described as a clinical syndrome of acute onset of cerebellar dysfunction with a good long-term prognosis. The pathogenesis of acute cerebellar ataxia remains unclear. A 55-year-old woman presented with acute onset of gait ataxia and dysarthria. The videonystagmography showed saccadic pursuit and saccadic abnormalities including slightly prolonged latency and hypometria. Rotational chair test revealed increased vestibuloocular reflex (VOR) gains and a failure of VOR suppression by visual fixation. Brain magnetic resonance imaging and cerebrospinal fluid examination were normal. The patient was treated with steroids and made nearly complete recovery over a period of 3 months.
Keywords: Acute cerebellar ataxia; Cerebellitis; Rotational chair test
