Reevaluation of ECT in Schizophrenia: Right Temporoparietal versus Bitemporal Electrode Placement

Two groups of schizophrenic patients received either bitemporal or right temporoparietal electroconvulsive therapy (ECT), both without anesthesia. Each patient received six treatments, the first three at 2-day intervals and the next three at 4-day intervals. Psychiatric evaluations and cognitive tests done at baseline, and 7 and 20 days after therapy, found similar degrees of improvement and similar effects on memory in both groups, with improvement in 40% and impairment in 30% of the patients. Subjective forgetfulness is more often experienced by the patients who receive bilateral ECT.
