Yes, there are a number of studies on slowed peristalsis, gastroparesis, etc.; I believe it was at first thought this was due to the meds, however, later studies speculate that this slowing of the ANS is part of the PD progression. I have to leave right now so can't go into further detail; however, there is definitely research in this area, and I would like to see much more done.
