[Maintenance electroconvulsive therapy--a review of literature]

Continuation and maintenance electroconvulsive therapy (ECT) is used to reduce the risk for relapse and recurrence of affective disorders and schizophrenic disorders. Despite the potential value of these ECT schedules, both are relatively neglected in clinical practice. This article reviews the recent research on the subject. Although most of the research are small open studies and case reports, continuation and maintenance ECT does emerge as a safe and effective treatment for relapse and recurrence-prone patients who have responded to the basic course of ECT.
