Safety and Efficacy Study of Deep Transcranial Magnetic Stimulation in Bipolar Depression

A Prospective, Double Blind, Randomized, Controlled Trial to Evaluate the Safety and Efficacy of the H1-Coil Deep Transcranial Magnetic Stimulation (TMS) in Conjunction With Mood Stabilizers in Subjects With Bipolar Depression

The purpose of the study is to evaluate the efficacy and safety of H1-Coil deep brain rTMS in subjects with bipolar depression, taking mood stabilizers and previously unsuccessfully treated with antidepressant medications.

This is a multi center, randomized, double blind study to evaluate the efficacy and safety of H1-Coil deep brain rTMS in subjects with bipolar depression, taking mood stabilizers and previously unsuccessfully treated with antidepressant medications. The study is designed for a period of 8 weeks of which up to 3 weeks subjects will be tapered down from their medications and treated for 5 weeks. Two follow up visits will be performed at week 6 and 8 after the last TMS treatment. Mood and mental status will be closely monitored with standard psychological scales and assessments

Inclusion Criteria:

• Outpatients
• patients 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.
• Men and Women Ages 22-68 years.
• Negative answers on safety screening questionnaire for transcranial magnetic stimulation.
• Taking mood stabilizing medication (e.g., Lithium, Lamictal, Tegretol, Topamax, etc.) at a therapeutic dose or atypical antipsychotic medication which was prescribed as mood stabilizers by their treating physician, except for Leponex (Clozapine). According to the treating physician the patient is compliant with taking the mood-stabilizing medication.

Exclusion Criteria:

• patients suffering from other diagnoses on axis 1 such as schizophrenia , or suffering from psychotic depression in current episode.
