Prolonged Toxic Encephalopathy following Accidental 4-Aminopyridine Overdose
Figure 1
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.
