I don't want to sound overly simplistic, but are you doing anything for the PD besides drugs? I am too new to this to rule anything out at this point. I keep hearing that some foods and exercises might be "neuroprotective." I saw a video recently of a man in Holland who was pretty bad off, but was doing amazing things on a bike. Then another video of a guy in Canada who claimed learning to ride his bike again made him stronger and reduced some of his pd symptoms. Has anyone tried food and exercise instead of or in addition to drugs for relief?
