[Towards the rehabilitation of maintenance electroconvulsive therapy?].

ECT is a reliable treatment of serious affective disorders more efficacious than antidepressants either used alone or combined with mood stabilizers or neuroleptics. Recurrent affective disorders refractory to all treatments presently available have been tentatively treated by prophylactic ECT since the beginning of ECT. In this study, 16 cases of recurrent affective disorders treated with maintenance ECT are discussed. Six continue to show a good response to maintenance ECT. Six remain improved although they discontinued ECT. ECT failed to improve 4 patients. Indications and inclusion criteria of maintenance ECT are defined. Good responses in cases refractory to all other treatment strategies are promising but still require prospective studies, difficult to implement, in order to confirm the efficacy of maintenance ECT.
