Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain. TMS therapy has been approved for the treatment of depression that has not responded to antidepressant medication. TMS has not been approved for the treatment of ADHD.
