The FDA has expanded the approved indications for transcranial magnetic stimulation (TMS) to include obsessive-compulsive disorder (OCD). In 2008, TMS was approved to treat major depression and in 2013 got the nod for pain from certain migraine headaches.
Transcranial magnetic stimulation uses magnetic fields to stimulate neurons in the brain. In a randomized multicenter study involving 100 patients, about half were treated with TMS and half received treatment with a sham device. Patients who were taking medication for OCD continued their usual dosages.
