A Case of Asymmetric Seizure Termination During an Acute Course of Right Unilateral Electroconvulsive Therapy.

Abstract

Abstract: Electroencephalogram (EEG) monitoring during electroconvulsive therapy (ECT) is commonly done using a 2-channel EEG in order to capture activity from both brain hemispheres, though many institutions may instead opt to utilize a 1-channel EEG, often for reasons of convenience. We present a novel case of asymmetric termination of EEG seizure activity during an acute course of right unilateral ECT, prompting a full neurological workup to investigate potential underlying structural or physiological causative factors. This case assists in informing the necessity of bilateral hemispheric EEG monitoring as well as highlights the importance of searching for undiagnosed or latent neurological dysfunction in certain clinical situations arising during ECT.
