There is an element of selfishness to this, I suppose. It feels pretty good to be able to so quickly help someone. That is, after all, one of the great emotional payoffs of medicine. That isn't to say that ECT is either a panacea or without flaws - but when used in the right way for the right purposes it's of great benefit, and condemning it because it isn't perfect would lead to more suffering and harm, no less.
