Evoked potentials in non-convulsive status epilepticus.
To verify the results from previous studies, we performed EPs on 2 patients with nonconvulsive status epilepticus who demonstrated ictal behavioral changes and bilateral, often diffuse electrographic abnormalities. The EP modalities which were used, PVERs, BAERs, and SSERs, are highly reproducible in normal subjects. In contrast to previous findings, the ictal EPs were normal. Our results may indicate that, despite bilateral and frequently generalized ictal activity in some patients with nonconvulsive seizures, sensory processing at the brainstem and visual and somatosensory cortices remains preserved.
