Urgent EEG after admittance.. (A) Urgent EEG showing the existence of bilateral continuous sharp-wave frontal activity consistent with nonconvulsive status epilepticus. (B) The same EEG showing intermittent burst of sharp waves of frontal-predominant distribution (black arrows). Horizontal bars = 1 s. Sensibility: 50 muV (1 mm vertical).

An urgent electroencephalogram (EEG) was performed (Fig. 1A) showing continuous generalized sharp-wave activity consistent with the diagnosis of nonconvulsive status epilepticus (NCSE) alternating with occasional bilateral-prominent frontal activity (Fig. 1B).
Control EEG performed 48 h after the start of treatment.. Control EEG, 48-hours posttreatment start, showing complete normalization of the trace with the exception of low-voltage transient sharp-wave activity on the left hemisphere (dotted box). Horizontal bars = 1 s, Vertical: 100 muV/cm.

Forty-eight hours later, a new EEG was performed, showing complete normalization of the trace with the exception of occasional left temporal bursts of low amplitude sharp waves (Fig. 2).
