TMS, or transcranial magnetic stimulation, shows promising results for some people with mental health conditions. Our Marietta psychiatrist provides the information you need to decide if this treatment is right for you Transcranial magnetic stimulation (TMS) is a non-invasive, outpatient procedure in which magnetic fields are used to stimulate specific nerve cells in the brain. During treatment, a small coil placed on the patient’s head sends painless magnetic pulses to the targeted area of the brain. TMS is well tolerated by the vast majority of patients. The person receiving TMS is awake during the treatment and can return to normal activities immediately after (no medication or anesthesia is required). Treatment time can range from five minutes to 60 minutes, depending on the type of therapy. A typical course of treatment is approximately 6 weeks.
