Myoclonus is a brief, rapid, involuntary muscle jerk originating in the central nervous system that can be physiological or a symptom of disease. We report a group of five children with excessive myoclonic jerks, only during sleep, and abnormal EEG during the events. Although only one third of the events had EEG epileptiform correlate, the presence of myoclonus without epileptiform EEG correlate has been described in patients with benign myoclonic epilepsy of infancy. We hypothesize that these findings may represent a variant of benign myoclonic epilepsy of infancy.
