Greg, I hope you found the person or information you need. Although much has been written about the effects of stress in general, I have found no scientific studies of the effect of stress on PD, although everyone who knows about PD knows about the increase in symptoms and has observed this phenomenon. (As I understand it, stress demands that the brain increase its production of neurotransmitters, and the substantia nigra, which already produces too little dopamine, cannot keep up with the increased demand.) I hope you're not in trouble.
