Dears In 1994 my wife Doris had a bilateral Palidotomy [spelling?] She also has been classified as a Parkinson Plus patient. It did little if any good. She never has the tremors only the stiffness and was not able to walk without help.She fell 5 years ago and has not walked since that time. She has had the problem for approx 8 years. We have never looked into the fetal tissue operation. Hope this may help you in some way. Best regard wegobill > -- Internet Communications of America, Inc.
