Deep Brain Stimulation, also known as DBS, is a surgical procedure during which a neurostimulator is implanted (also known as a ‘pacemaker for the brain’) into the area just under the collarbone. Electrodes extending from the neurostimulator are then placed at specific areas of the brain (known as DBS targets). When stimulated, the electrodes affect the corresponding nerve signals directly, and so may reverse the symptoms of the patient. The intensity of the electrical pulse is adjustable, and as such, any stimulation-induced side effects are reversible. While DBS is invasive in that surgery is required, DBS does not damage the brain tissue in any way.
