Madelyn,

It's true there is no really good animal model. Further, I remember learning that my cousin's dog came down with Addison's disease, and we know pets get cancer or can be epileptic. Animals can have an essential tremor, but I have yet to hear of them developing PD? If environment is a player wouldn't it be resulting in PD in them as well. Even when they induce lab animals for PD research there is no degenerative process that takes hold, I think, or may be someone knows differently.

I didn't mean to come down so hard, I just don't get where the therapeutics come in. I'll have to see if I can find the original article. I think the write up of the study is ambiguous.
