Query: FDA approved vagus nerve stimulation-a much better therapy

In February of 2005, the FDA approved vagus nerve stimulation as a treatment for chronic depression. With this approval, for many patients electro-convulsive therapy will no longer be the most aggressive way to treat their chronic disease. Max Fink's book is very helpful in explaining and comforting a patient that is fearful of ECT. There is a terrible stigma associated with shock therapy. If it works, the relapse rate is high. For my money, I think I will go with vagus nerve stimulation and its benefits which are apparently sustained over a long time.
