Summary
Brief summary
This is a study to assess the effectiveness of repetitive transcranial magnetic stimulation (rTMS) as a treatment for depressed adults with bipolar disorder. In rTMS high-intensity, fluctuating magnetic fields non-invasively stimulate the cortex of the brain depolarising neurons. No anaesthetic is required and the treatment in subconvulsive. Recent studies suggest that rTMS can be an effective treatment for depressive illness in adults (Loo and Mitchell et al, 2005) and appears to be quite safe. Most of the published studies to date have focused on unipolar depression. There is limited data of TMS use in bipolar depression. Eg. Pilot study by Nahas Z, Kozel FA, Li X, Anderson B, George MS.in 2003, which was negative. The investigators wish to assess this in a sham-controlled study of adults. The investigators hypothesise that both left and right sided rTMS will have an antidepressant effect superior to sham in this population.
