William I do pallidotomies for Parkinsons. It's a good operation which has positive effects on bradykinesia, drug induced dyskinesiae, rigidity, on-off and cramping. In many cases it improves gait. Younger patients such as yourself do very well. It involves a 3-4 day stay in the hospital, and a 2 hour surgical procedure done under local anesthesia. Electrophysiologic mapping is a part of the surgery to refine the final target coordinates. Hope this helps. Patrick J.
