This is an open-label study designed to investigate the feasibility and tolerability of a novel TMS treatment protocol to treat depression in women with post-partum depression. It is known that TMS can effectively treat depression. The FDA approved protocol lasts 6 weeks and is not feasible for many women with post-partum depression. We are investigating a 3 day treatment for depression which may be more acceptable for this population. We further hope to characterize the ant-depressant effect of this protocol in order to design a larger trial.
