Abstract

Hashimoto's encephalopathy (HE) is an uncommon syndrome accompanied by Hashimoto's thyroiditis. It is an immune-mediated disorder characterized by subacute onset of confusion, altered consciousness, seizures and myoclonus. However, the diagnosis is often difficult because clinical manifestations are heterogeneous and nonspecific. Several reports of Hashimoto's encephalopathy presenting with focal or generalized seizures are described, but only few have focused on status epilepticus as the first clinical manifestation. We report a 60-year-old female patient who developed decreased consciousness with nonconvulsive status epilepticus due to Hashimoto's encephalopathy and was successfully treated with high doses of intravenous steroid.
