OCD is generally treated with medication and therapy. Unfortunately, about 20% of people with OCD do not respond to normal treatment. Luckily, researchers are investigating new types of treatment for these severe cases.

Deep brain stimulation involves surgically implanting two electrical stimulators in the brain, which are connected to a pacemaker-like device that turns them on and off. 25-50% of the patients who have undergone this procedure at Brown University have experienced improvement from it.

Gamma knife capsulotomy is another surgical procedure in which specific areas of the brain are cut with special device called a "gamma knife." 60% of the patients who have received this procedure at Brown have experienced improvement.

Both procedures are still being investigated, but the initial results certainly seem encouraging.
