Fig. 1 13 years old boy. On the left: typical absence associated with classic ictal EEG pattern of bilateral synchronous and symmetrical 3Hz S-SW discharge. On the right: typical absence; at EEG we observe a preceding short focal onset of 3Hz S-SW in frontal and anterior temporal right sides before the diffuse discharge.
