Transcranial Magnetic Stimulation (TMS) is one of the most effective antidepressant treatments available and has been approved by the FDA since 2008. It is a safe, non-invasive, brain stimulation therapy that has been shown to be effective in medication-resistant depression. TMS is a brief, outpatient procedure that involves using an MRI-strength magnet to produce electromagnetic pulses that stimulate an area of the brain (dorsolateral prefrontal cortex) believed to be underactive and responsible for causing the symptoms of depression. A typical course of TMS lasts 4-6 weeks and depends on a patient’s response to treatment. The procedure is delivered daily (Mon-Fri) in 30-45 minute sessions. Patients can resume normal daily activities after each session.
