Transcranial magnetic stimulation is approved for use in adult patients who have completed at least one trial of antidepressant medication without success.
Transcranial magnetic stimulation uses magnetic pulses to stimulate nerve cells in the brain involved in mood regulation and depression. TMS is an outpatient procedure that doesn't require anesthesia, surgery or the implantation of electrodes. Patients usually have five brain stimulation treatments each week for up to six weeks .
