I'd like to introduce myself. My name is Nancy Everitt. I live in Eau Claire, Wisconsin. I subscribed to this list because my grandmother Betty who lives in Holmen, Wisconsin was diagnosed with PD a few years ago. She has progressed to the point that her right arm and hand are so crippled that she can hardly dress herself. And one of her legs continually drags. I am hoping to gain as much knowledge of PD and treatments, etc as I can from this list. So far it has been very interesting. After reading the post last week (I think) about the article pertaining to Fetal Attraction in the Discover Magazine, I purchased the mag and read the article. It was incredibly interesting. I would recommend that anyone read that article. The reason I am writing now is that the previous posts about "hedgehog" have me very interested. Does anyone know if there has been information published pertaining to the research on "hedgehog"? If there is, could you please let me know where to find this information? I'd be sincerely grateful! :-) Nancy Everitt, Eau Claire, Wisconsin ([log in to unmask])
