Preservation of the brainstem auditory evoked potential in non-convulsive status epilepticus.
Brainstem auditory evoked potentials (BAEPs) were recorded from a patient simultaneously experiencing non-convulsive generalized status epilepticus (NGSE). Waves I, III and V were normal but all subsequent waves were absent. This finding indicates that structures within the brainstem adjacent to the generators for the BAEP are likely not affected by NGSE and also illustrates the resilient nature of the BAEP. This is the first report of the recording of an evoked potential during a naturally occurring generalized seizure.
