Transcranial magnetic stimulation

Although multiple psychotherapy and medication options exist for treating major depression, they don't work for everyone.

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. First, some caveats.
