Thank you very much, Madam Chair.
Good morning, and thank you, witnesses, for coming here this morning.
I have a few questions that will follow up on the questions that were asked.
My first question is for Dr. Krewski. In the study you are conducting currently, you're doing several other diseases, not only Parkinson's. You and Dr. Hu stated that there are several causes of neurological disorders: pesticides, food, etc. Is there a geographical aspect of those diseases or of Parkinson's in particular? As far as I know, and I might be incorrect, there are places, for example, where people do not get MS. Is this the case with Parkinson's or other diseases that are part of your study? If that's the case, do we have any idea why it is so?
