EEG recordings performed upon admission of the patient to the ICU (a) and at day 8 (b). (a) EEG traces show continuous epileptiform spikes and spike-waves at 2 Hz on the left frontocentral regions on a generalized slowed background intermixed with medicamentous beta waves. (b) EEG shows irregular short bursts of slow spikes and delta waves on the left frontocentrotemporal regions. Background activity at day 8 still shows diffuse beta waves, of medicamentous origin.

The first EEG recording, performed upon admission to the ICU 12 hours after initial symptoms, showed generalized slowing at 6-7 cycles per second with abundant irregular spike- and polyspike-waves on the left frontocentral regions (Figure 1(a)). As the sedation was reduced, EEG became gradually continuous with diffusely slow background activity at 6-7 cycles per second but still showed bursts of delta waves intermixed with slow spikes on the left frontocentral regions (Figure 1(b)).
