please, i am asking for answers or good reliable links to answers, ok? im not wanting opinions just now. no offense intended.

someone dear to me is being told to do ECT and i don't know what to say or think... i know someone years ago who had it, but we've lost touch and although he had long term depression and felt it was the right treatment, his depression was not so deep that he couldn't function. He didnt need many. He didnt lose any memory really except for a short time frame around the treatments.

does it work? always or some of the time? ever? can they do it without so much memory loss?

im so worried
