I am curious about the possible connection between exposure to pesticides and pd. I know that it has been looked at but I also know that a meeting I went to about 3 years ago with top researchers in the field of pd, no one had really done a significant study on this subject. This is not to say no one has, but in this group no one had. I wonder if you (Shannon) could identify which pesticides your father in law used most as a beginning and the rest of us could see if there was ever any significant exposure in our lives to that substance. I realize this probably won't contribute to a cure but perhaps a preventive for the future. As always, searching for explanations. Den
