Abstract
A 17-year-old girl had experienced only one episode of non-convulsive status epilepticus (NCSE) at age 7 months. NCSE appeared 2 days after cyproheptadine hydrochloride administration for upper respiratory infection. EEG (and movement) during NCSE showed a cyclic pattern; (1) diffuse 2Hz high voltage slow waves with spike rhythm (akinetic status)→(2) suppressive phase (presence of involuntary or voluntary movements)→(3)<6Hz waves arising from P3-O1 spread to the whole surface (decrease of motion)→(1). She recovered immediately after diazepam adminis-tration.Clinical and EEG findings during this episode were similar to those of complex partial seizure (CPS);thus the cause of NCSE was considered complex partial status epilepticus.She had no further episode of seizure or abnormal EEG until age17. The favorable outcome suggests that the episode of NCSE was due to benign infantile partial epilepsy which includes benign CPS in infancy or a side effect of cyprohe-ptadine hydrochloride.
