I thought you might look at the TED talk by Sherwin Nuland (on Youtube) https://www.youtube.com/watch?v=oEZrAGdZ1i8&feature=player_detailpage Nuland was a surgeon and professor at Yale, author of many books, and he speaks about his positive experience of ECT. Also I have a book by Edward Shorter and David Healy called Shock Therapy: a history of electroconvulsive treatment in mental illness. It was published in 2007 by Rutgers. I haven’t read it yet, but I like both authors. Good luck with your studies.
