Summary

This is a prospective, 8-week, double blind, randomized, controlled, multi-center trial in outpatients recruited in both academic and private research centers. The proposed study will compare two groups of patients with bipolar depression (BP1 and BP2). one group will be assigned to the DTMS treatment (H1 coil), and the other group will be assigned to the sham treatment (sham coil). The patients' clinical condition will be assessed before, during and after the treatment in order to evaluate their response to the H1-coil rTMS treatment. Both groups will be stratifed according to symptom severity. The treatment group will receive 4 weeks of daily DTMS treatments with the H1 coil followed by 3 treatments in week 5 and 1 treatment in week 6, for a total of 24 treatment sessions and 1980 magnetic stimulations per session. The control group will receive the same treatments with a sham coil, for a total of 24 treatment sessions, as well. each DTMS session will consist of 55 trains. The duration of each train will be two seconds and the inter-train interval will be 20 seconds.

Participant Eligibility


* Outpatients

* Diagnosed as suffering from an episode of bipolar depression (BP1 or BP2) according to DSM IV, with the additional requirement of duration for the current episode >= 4 weeks and CGI >= 4.
