Cerebellar Ataxia Associated with Glutamic acid Decarboxylase Autoantibody (Anti GAD)

Abstract

Cerebellar ataxia implies changes in motor coordination and balance. An etiological study is difficult given the countless differential diagnoses. Autoimmune causes, namely due to anti-GAD antibodies, represent only around 2% of progressive cerebellar ataxia in adults [1]. The case presented is of a woman with a history of epilepsy and alopecia universalis that began to show a condition of cerebellar ataxia whose study revealed an autoimmune ataxia with positive Anti-GAD 65 antibodies. Therapeutics with intravenous immunoglobulin enabled partial improvement of the symptoms.
