Just like a pacemaker for the heart, a small device  is surgically placed under the skin in the chest to deliver DBS therapy. The device sends electrical pulses through the extension  to the leads  that are placed in an area of the brain that controls movement. These pulses disrupt some of the brain’s messages that cause the symptoms associated with Parkinson’s disease. DBS therapy is reversible and can be discontinued at any time by turning off or surgically removing the device.
Class One clinical evidence shows that DBS is superior to the medical therapy in patient with Parkinson’s disease and early motor complications:1
