Transcranial magnetic stimulation
Research helps clarify who is likely to benefit from this treatment.
Although multiple psychotherapy and medication options exist for treating major depression, they don't work for everyone. Patients who have not responded to medication, or who have not been able to tolerate other options, may be eligible for repetitive transcranial magnetic stimulation (rTMS). The FDA in 2008 approved the first repetitive rTMS device specifically for treating major depression that has not responded to at least one medication taken at adequate dose and duration (usually defined as at least four weeks). A federally funded study provided further guidance about its use.
