(A) Ictal EEG with bipolar montage (standard 10–20 electrode system) demonstrating diffuse onset of rhythmic spike–polyspike and wave discharges during rhythmic clonic jerking of the right arm; (B) ictal EEG with average referential montage of the same patient during a head drop seizure. Diffuse slow wave and attenuation is noted at clinical onset.
