I saw the March 15th program on 20/20 about the brain stimulation proceedure at the University of Kansas Medical Center. They interviewed Dr. Koeller (not sure of the spelling) and two patients who have undergone the surgery. The segment included tapes of the patients before and after the surgery and showed how it almost totally relieved their tremors. It also showed how they could turn the implanted stimulator on and off with a small magnet. I may have missed some of the report (having been interrupted a number of times), but they never referred to the procedure as pallidal stimulation surgery, although it sounded just like it. I also noticed that it was described as effective treatment for tremors, but didn't discuss it's role in PD treatment. Did anyone else who saw the program have a similar reaction or know more about Dr. Koeller andd the University of Kansas program? Let me know if I just didn't get all the information right. Thanks.
