Several myoclonic jerks are polygraphically recorded when awake, persisting during drowsiness, and, attenuated, during sleep stage II in a 2-year-old girl before any treatment. The jerks are accompanied by generalized spike wave, sometimes preceded by spike wave localized in the anterior regions. The same type of generalized discharge appears during REM sleep without concomitant clinical event. R. DELT = right deltoid muscle, L. DELT = left deltoid muscle.
