RESUMEN
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.
Distúrbios neurológicos associados com anticorpos anti-GAD são doenças pleomórficas, raras, de causa incerta, das quais a rigidez muscular espasmódica (SPR) é a mais conhecida. Neste estudo, descrevemos nove casos consecutivos de distúrbios neurológicos associados com a presença de anticorpos anti-GAD, incluindo nove pacientes com SPR e três casos com ataxia cerebelar. Adicionalmente, foram encontrados quatro casos com hipotireoidismo, três com epilepsia, dois com diabetes mellitus e dois casos com mioclonia axial.
