TMS Therapy

Transcranial Magnetic Stimulation Therapy

St. Joseph Hospital is proud to be the first hospital in Orange County to offer transcranial magnetic stimulation (TMS) therapy. This non-invasive treatment is FDA-approved for patients with Major Depressive Disorder who have not been able to regain their quality of life from talk and/or medication therapies alone. In fact, clinical trials have shown that TMS therapy is a proven safe and effective treatment to help patients achieve long-term remission from MDD.

How does TMS therapy work?

TMS therapy works by using a pulsed magnetic field to stimulate a specific area of the brain (left prefrontal cortex) involved in mood regulation. The magnetic stimulation delivers pinpoint accuracy to the targeted brain region, which results in an improved mood.

TMS is delivered through a small, curved device with a magnetic coil that rests on the patient’s head. Patients remain awake and alert during TMS therapy sessions, which take less than 20 minutes to complete. Once the treatment session is complete, the patient can resume normal activities immediately. The most common side effect reported with TMS therapy is mild discomfort near the treatment site, which typically subsides after the first week of treatments.
