Neurological disorders associated with glutamic acid decarboxylase antibodies: a Brazilian series

Abstract

Neurological disorders associated with glutamic acid decarboxylase (GAD) antibodies are rare pleomorphic diseases of uncertain cause, of which stiff-person syndrome (SPS) is the best-known. Here, we described nine consecutive cases of neurological disorders associated with anti-GAD, including nine patients with SPS and three cases with cerebellar ataxia. Additionally, four had hypothyroidism, three epilepsy, two diabetes mellitus and two axial myoclonus.
