Transcranial Magnetic Stimulation (TMS) for the Treatment of Depression - Research Study Information

Overview

In rTMS therapy, a device called a stimulator provides electrical energy to a magnetic coil that delivers a magnetic field. When the coil is placed against the scalp on the left front region of the head, the magnetic field is focused to a region of the brain that is thought to be involved in depression. This study tests the theory that the electromagnetic field created by the coil affects this region of the brain in a way that may improve the symptoms of depression.  This may affect brain activity and function.

The study is in three parts. The first part requires daily (M-F) visits to your study doctor over a 3 to 6-week period. Each session will last about one to one and a half hours. The total time in the first part may be up to 7 weeks. You will be randomly assigned to either active (real) rTMS or sham (placebo) rTMS. You may or may not respond to the treatments provided. In either case, you will be given the option to continue in a follow-up study. Responders can choose to enter a 6-month maintenance study (Phase III) and non-responders can choose to enter a 3- to 6-week study where all patients receive active rTMS (Phase II). Patients who respond to the 3- to 6-week active rTMS treatment may then go on to the 6-month maintenance study as well.  rTMS treatments will not be available after your completion of the studies, even if you respond to treatment. At various time points, you will be asked questions about your memory and depression and receive other tests. All of our services are provided free of charge.
