Figure 1

Illustrative EEG of one of the patient's myoclonic epileptic seizures. Shown are two bursts of irregular, frontally predominant, generalized spike-and-wave complexes in a longitudinal bipolar montage (A) and average referential montage (B). One of the bursts was associated with a myoclonic seizure (white arrow in both panels). The myoclonus occurred during the slow-wave component of the burst, as shown on the EMG (electromyography) lead in this image.
