Hi, I just joined Neurotalk...I'm not familiar with how this website works yet. I have PD also, DX 'd at age 61 six years ago. I think it will depend on how well you take care of yourself. Exercise, according to those who do it, and I believe research is starting to back this up, is critical and even neuroprotective. Take some of the supplements mentioned on good PD websites. I would not worry about the outcome. Just try to live each day to the fullest, stay connected with your dear ones, get enough sleep, eat a diet rich in vegies and fruits, and go to a good neurologist, preferably a Movement Disorder Specialist. If your neurologist is a good one who prescribes the meds that are best for you and you do all of the above, you're likely to have slower progression (in my opinion). Handling stress better also protects the neurons in the brain. Prayer and the support of others have also been very important to me.
