Evaluation of the H1-Coil TMS- Double Blind Placebo Controlled Study in Adolescent Patients Suffering From Major Depression

This study is a randomized double blind placebo controlled EEG monitored study of deep rTMS treatment to treat adolescent depression. The present study is the first well controlled study to examine the possible clinical utility of deep TMS to treat a severe and life threatening disorder- depression, among adolescents. Patients will be allocated, based on chance, to receive active therapy or a "as if" stimulation, with no knowledge of patient or therapist who receives the active therapy. In addition, a simple and feasible monitoring of brain waves (EEG) will be conducted. This addition will enable us to evaluate the possibility to use biological markers to predict the course of therapy. Our hypothesis is that 1. patients receiving the active therapy will improve significantly more than those who received the "as if" treatment. 2. There will be no significant side effects. 3. The brain waves (as measured by the EEG) will predict treatment response.
