Long Description

Dale suffers from Parkinsonís disease (as shown in the video “Parkinsonís Disease: A Case Study”). In this video, Dale learns he will receive a revolutionary new treatment at the Cleveland Clinic. In deep brain stimulation, electrodes are implanted in both sides of the brain and linked to two small generators, which are comparable to heart pacemakers. The electric charge that is delivered is expected to relieve Daleís symptoms. A computer, MRIs, and CAT scans guide the surgeon to the target, about the size of a small olive, deep within Daleís brain. The surgeon describes the route as a labyrinth. Two dime-sized holes are drilled in Daleís skull. It is important that he remain conscious and communicative throughout the procedure to ensure that the surgery does not disrupt his speech and vision. A tiny microphone at the end of the probe enables surgeons to hear the brain activity essential to locating the target. A test charge of electricity delivered to Daleís brain produces the desired muscle control. As the tiny electrodes are permanently implanted deep within his brain, Dale demonstrates renewed capacity to open and close his hand. The surgeons express confidence that the surgery has been successful. Dale returns to the Cleveland Clinic a month after surgery. Clearly the intervention has been a huge success. He is able to walk, his facial muscles are relaxed, and his speech is much improved. He reports that he again intends to play music, shoot pool, and enjoy “wild, passionate sex.” The power system that delivers impulses to the electrodes is adjusted. Turning the small pacemakers on and off dramatically demonstrates the difference that stimulation makes in terms of Daleís ability to control his body. He describes the experience as comparable to turning a light switch on and off. The surgeons report that the outcome is representative of the new procedureís impact on Parkinsonís victims.
