Continuation ECT in the management of relapses of major affective episodes.

Three cases are reported describing the use of continuation ECT. Continuation ECT consisted of six to twelve treatments for about 3 to 6 months after recovery from the index affective episode. Continuation ECT may be indicated in patients with a severe episode of illness, optimal acute response to ECT, and negative response to continuation drug therapy. In such patients, the mostly theoretical risks associated with the procedure may be outweighed by the dangers associated with early relapse.
