Side effects of ECT, the possible memory loss is a topic for debate. Not only between psychiatrists but also between patients. Here is another story of how these side effects ruined the life of a patient. Made a comment to this post but it was not published on the blog as a comment. Here is another more positive opinion about ECT from a patient.
Side effects will be a topic for discussion for a long time. On this blog two other views are described in 2 posts. First a view from Prof Max Fink and here a post about an ongoing discussion with Prof Sackeim.
I will post your comment anyway.
