 Deep brain stimulation is a surgical procedure performed to ease motor symptoms in patients diagnosed with Parkinson's disease. Pre-procedure, you undergo routine blood tests and body scans. Patients typically remain awake during the DBS procedure but are given medications to relax and feel no pain. During the procedure, the surgeon places thin wires called electrodes into one or both sides of the brain that control movement. Once the electrodes are in place, the surgeon connects them to a battery-operated device similar to a cardiac pacemaker which usually is placed under the skin below the collar bone. This device, called a neurostimulator, delivers continuous electrical pulses through the electrodes. The entire procedure takes 4-6 hours. You will remain in the hospital overnight for observation and recovery. A few weeks after the surgery, the doctor switches on the implanted pulse generator through a handheld device and the electrical pulses are adjusted until symptoms improve.
