Deep brain stimulation (DBS) therapy for OCD targets precise areas of the brain linked to obsessive-compulsive disorder.
DBS uses a surgically implanted medical device, similar to a cardiac pacemaker, to deliver carefully controlled electrical stimulation. The stimulation is sent to a precisely targeted structure within the brain, the anterior limb of the internal capsule (AIC).
DBS may treat the symptoms of OCD. It is not a cure, and some symptoms may remain even with the treatment. If stimulation is discontinued, the symptoms will likely return.
The DBS system is implanted inside the body and includes the following components.
These electrical pulses are delivered through the extension and lead to the targeted areas in the brain. Your clinician can adjust the pulses wirelessly to check or change the neurostimulator settings.
Once the neurostimulator has been activated following surgery, it can be programmed by your clinician to find the level of stimulation that maximizes benefits while minimizing side effects. The clinician uses a programming device to make non-invasive adjustments to the neurostimulator. It may take several months to find the right level of stimulation.
Depending on the system and your therapy needs, you may have a controller that will allow you to turn the system on and off, adjust the stimulation, and check the battery.
How long the neurostimulator's battery lasts depends on the settings. Before the battery runs out, the neurostimulator can be replaced in a surgical procedure that does not require an overnight stay in the hospital. Leads and extensions don’t typically need to be replaced.
