Ron - I agree with the people who recommend Deep Brain Stimulation (DBS), specifically of the Subthalamic Nucleus (STN). Pallidotomy is outdated. It's also permanent, and if a cure should come along in the next several years, someone who has had a pallidotomy may very well be excluded from using it, depending on what form the cure takes. Furthermore, if you do some research, you'll find that pallidotomy results tend to be less effective over time. Furthermore, only one side of the brain can be treated with pallidotomy. Bilateral pallidotomy causes some severe side effects, and is generally not done anymore. DBS of the STN is reversible, and the electrodes can be removed if something better comes along. Early evidence seems to show that DBS results actually improve over time. The best results do depend on getting a good stimulator setting, but of course first there has to be good placement of the electrodes. You definitely want to look into a center with experience. Toronto would be close to you, I believe, and has the most experienced surgeons in North America. The most experienced in the US is Dr. Steven Wilkinson at the University of Kansas Medical Center in Kansas City, Kansas. We can highly recommend him and the results he achieves.
