The ictal EEG (long arrow) with initial high amplitude (400-700 microvolts) frontally predominant generalized polyspikes (long arrow) followed by 2-3 Hz generalized spike and wave (short arrow). Also note the intermixed polyspikes with the spike and wave. The background dominant rhythm was slow for age.. The absence seizure was associated with staring, subtle behavioral arrest and up rolling of eyeballs. Patient was not able to recall the words given during this event.

Ictal EEG recordings showed an initial high voltage (> 400 microvolts) generalized 14-18 Hz polyspikes, which occurred in isolation or followed by 2-3 Hz GSW discharges (Fig. 1).
