When I read this, I said, "That's it!" at least in my case. and I can definitely say my symptoms worsen when my head (sinuses) are all stopped up (and vice versa).

This was a report on a webcast so the transcript is not yet available. I'll post it here when it's out:

I have two questions:
1. Can we prevent PD in these cases by treating the allergies early?
2. Can we stop PD progression (if caused by allergies) by eliminating the allergy symptoms?

I think I know my PD cause now. It's a small study, but makes a lot of sense.
