Bill, I was in Toronto yesterday for a follow-up pallidotomy visit and asked Dr. Lazano if they were still refusing to do bilateral pallidotomies. He said they were because the reports from other institutions who do the surgery showed that 80 percent of rhose operated on the second time experienced serious speech difficulties. He also said that Dr. Lang's research showed a negative effect on cognitive ability. He uses the pacemaker implant for the second side. Joan Holliday
