I had a friend who did ECT for major depression. It really helped him. His depression came back later and he did it again. He was glad to find something that helped as the meds and psychotherapy he had tried had not. The only down side was that he seemed to suffer partial and permanent memory loss. But he felt ECT was worth it since it helped with his depression. Anyway, something to consider, I believe memory loss is a not infrequent effect of this treatment. Good luck
