Hi, Julie, you have taken on a large task. It seems like every one of us is so different wih regard to response to PD meds and progression of the disease, it's almost like we all have a different disease, or that is my impression from being on the List for the past 2 years. I'm starting to lose my voice, something I never thought would happen. Being a former teacher I could project it to the back of any room or auditorium or talk down noisy students. My grandfather had PD too and died of its complications at 76. I am 66 and have had it almost 7 ys. Good luck in your studies and see that you NEVER get PD.
