Hi all, I have found out more about the person I know that has parkisons. On top of having no dopamine in her brain she also have extreme chemical sensitivity. (The parkinsons was caused by these chemicals but they also caused the chemical sensitivty as well) So she gets very sick from any foreign scent and on top of that she has absolutely no coping ability (lack of dopamine). Their Parkinsons was caused by window screens. There was some extreme toxic chemical in these screens. It actually killed their cat because the cat used to sit by the window screens and watch the world go by. There was a whole community somewhere in the states that had the same effects from these window screens. I don't know exactly where but if anyone was interested I could find out. -Claire Polomark
