Kathy-- you don't say what level of school you are in, which makes a difference in how folks reply to you. You ask BIG questions, too! May I suggest that you can find basic info re: symptoms of PD inliterature available from the national organizations (Nat'l PD Fndtn=1-800-327-4545, American PD Assn= l-800 223-APDA). I expect you will hear from someone on the list, but I will add quickly that the 3 MAJOR symptoms of PD are tremor, rigidity, and slowness (bradykinesia ), but there are MANY others and no two people have EXACTLY the same combination, so it's not so simple! Have you thought of checking a med ical encyclopedia in your local or school library? (You didn't say,either, what your deadline is--- Camilla Flintermann,CG for Peter 78/7,Ohio
