An electroencephalogram (EEG) performed on his second day, off sedation, revealed continuous periodic sharp and slow wave complexes at around 1Hz with intermittent high amplitude
The EEG traces show a general slowing of the background activity, more evident on the right hemisphere, where periodic sharp complex are evident, often time-locked with myoclonic
