Juvenile myoclonic epilepsy with absences (EEG) (1)

From video-EEG of a 25-year-old woman with juvenile myoclonic epilepsy. Note the discharge fragmentation and the irregular intradischarge frequency. No apparent ictal clinical manifestations except some mild eyelid flickering or hesitations in pronouncing numbers (not shown). Also, note the independent focal spikes in the right frontal regions.
