Autoimmune cerebellar ataxia with glutamic acid decarboxylase 65 antibodies associated with central vestibular symptoms.

The spectrum of neurological syndromes associated with antibodies to glutamic acid decarboxylase 65 (GAD65-Ab) includes cerebellar ataxia (CA), stiff-person syndrome, limbic encephalitis, progressive encephalomyelitis, and some refractory epileptic patients [1]. We describe a patient presenting with central vestibular symptoms preceding CA related to GAD65-Ab, supporting evidence of relationship between central vestibular pathology and GAD65 autoimmunity
