Dear Judy, <[log in to unmask]> I think you might have me confused with someone else. I do not determine who should or should not go through the pallidotomy procedure ...with the exception of one person ....me. I've written my viewpoint for those that are interested ....nothing more; nothing less. There is no hidden agenda nor axe to grind. As to the details of the procedure, it's history, and it's progress, see: "Parkinson's Disease: The Search and the Promise", Pixel Press, ISBN# 0-9620354-1-6, Library of Congress #92-093912 "Parkinson's: A Patient's View", by Sidney Dorros, Seven Locks Press, ISBN #0-932020-08-9 New England Journal of Medicine, Index: Parkinson's Disease "Parkinson's Disease: A Guide for Patient and Family", by Roger Duvoisin, Raven Press, ISBN #0-88167-711-6 "Parkinson's Disease: Biochemistry, Clinical Pathology and Treatment" by Walther Birkmayer, Springer-Verlag, ISBN # 3-211-81722-0 Progress in Parkinson Research, Edited by Franz and William J. Weiner, Plenum Press, ISBN #0-306-43096-7 And many many more - too many to mention. If all else fails, get in touch with Alan Bonander <[log in to unmask]>, who has a good video of the procedure performed on himself in Sweden a couple of years ago. Hope this is helpful to you. VernD
