Hi levon, "electro-thearpy" is a pretty way of say ECT Electroconvulsive Thearpy which is as old as time. In the last 20 years they have refined the treatment but it is still very much questionable as to weither or not it has a long lasting effect on helping depression. Also, most people have to have these treatments quite often and they are given in combination with medications at times. I would most certianly seek with a physician before even considering this form of treatment as it can have efffects that may not go away.
Here is some info on it....
