Can Magnetic Brain Stimulation Help Prevent Relapse in Depression?
The Efficacy of Repetitive Transcranial Magnetic Stimulation in Relapse Prevention of Major Depressive Disorder
The purpose of this study is to investigate the use of repetitive transcranial magnetic stimulation (rTMS) in helping to prevent relapse in major depressive disorder. rTMS is known to be an effective treatment for major depressive disorder, but there is also evidence that it may be effective in the maintenance of remission following treatment. However, it is not yet clear what maintenance strategy will yield the best outcome in preventing relapse.
In this study, eligible patients who have finished one full course of rTMS for treatment of major depression will be randomized into three groups: (i) cluster rTMS, (ii) taper rTMS, and (iii) treatment as usual. The 'cluster rTMS' group will receive two weeks to daily rTMS six months after the completion of their regular rTMS treatment, the 'taper rTMS' group will receive three sessions a week for two weeks followed by two sessions a week for two weeks immediately following their regular rTMS treatment, while the 'treatment as usual' group will receive standard follow-up care from their own psychiatrist and/or primary care doctor.
The investigators hypothesize that the group with cluster treatment will show significantly lower relapse rates in depressive symptoms as compared to the other groups.

Detailed Description
The purpose of this study is to investigate the efficacy of rTMS to the dorsolateral prefrontal cortex (dlPFC) as a maintenance therapy following standard rTMS treatment in major depressive disorder.
A total of 45 patients will be recruited for this study. Patients who have completed a standard six-week rTMS treatment for major depressive disorder will be randomly assigned to one of the three groups: cluster rTMS, taper rTMS, and treatment as usual. Patients in the 'cluster' group will receive two weeks of daily rTMS (10 rTMS sessions) six months after completing their rTMS treatment. Patients in the 'taper' group will receive rTMS immediately after completing rTMS treatment and the frequency of the sessions will be tapered as follows: three sessions a week for two weeks, and then two sessions a week for two weeks. The maintenance plan for patients in 'treatment as usual' group will be decided individually and may include any or all of the following: continue or start on medication, start psychotherapy and/or follow-up visits with psychiatrist or primary care provider.
Each session of rTMS will be identical: lasting about one hour and consisting of 3000 high frequency (10 Hz) pulses. After finishing their last session of rTMS treatment, all patients will be seen by the rTMS psychiatrists bi-monthly for one year. Each visit will last approximately half an hour during which time the Hamilton Depression (Ham-D) Scale will be administered.
Given the high relapse rates following rTMS treatment for depression, the investigators hope that results from this study will be very helpful to patients suffering from major depressive disorder in improving their quality of life by reducing their rate of relapse.
