I do ECT every 2 weeks because I have very strong suicidal thoughts that just disrupt my thinking. ECT is the only thing that has helped. The medication helps the overall depression but the suicidal thoughts (and actions) can be life threatening for me. I asked the doctor about clinical trials for Deep Brain Stimulation that I had read about, but he said they were more for OCD and Parkinson. So I will stick with the ECT.
Take care everyone
