Lucile Wright, My pleasure. Enjoy your ice cream. My underlying point is one should never depend on the neurologist for the total picture of information on Parkinson's Disease. Learn all you can about your disease as you can. The neurologist is a busy person. Busy with more disorders than just Parkinson's, and sometimes he is so busy he cannot stay as current with the literature as you can. Besides, if you have PD it is in you best interest to learn all you can about the "stuff" so that you can ferret out the true information from the mis-information yourself. I would like to suggest the following books: "Parkinson's: A Patient's View" ISBN 0-932020-09-7 "Progress In Parkinson Research" ISBN 0-360-43096-7 "Parkinson's Disease: The Mystery, The Search and the Promise" ISBN 0-9620354-1-6 "Parkinson's Disease: A Guide for Patient and Family" ISBN 0-88167-729-9 Read, enjoy, and learn, VernD
