In contrast to several other well-characterized autoantibodies, GAD-Ab has very rarely been associated with status epilepticus. We report a 63-year-old woman initially admitted with somnolence and psychiatric findings. The EEG findings, of generalized and rhythmical slow spike-wave activity over the posterior regions of both hemispheres, together with the clinical deterioration in responsiveness, led to the diagnosis of non-convulsive status epilepticus. Investigation of a broad panel of autoantibodies, revealed only increased serum GAD-Ab levels. Following methylprednisolone and intravenous immunoglobulin treatments, the patient's neurological symptoms improved, EEG findings disappeared and GAD-Ab levels significantly decreased. GAD-Ab should be added to the list of anti-neuronal antibodies associated with non-convulsive status epilepticus. Disappearance of clinical findings and seroreversion after immunotherapy suggest that GAD-Ab might be involved in seizure pathogenesis.\u00a0<\/jats:p>","DOI":"10.1177\/1550059412459330","type":"journal-article","created":{"date-parts":[[2013,7,2]],"date-time":"2013-07-02T07:48:28Z","timestamp":1372751308000},"page":"232-236","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Non-Convulsive
