I feel that my PD is progressing faster than what I was lead to believe is usual. The thought has occurred to me that I might have PSP instead of PD and was wondering if anyone has talked to their doctor about what distinguishes PSP from PD. Do you know of a test for PSP? I plan to ask my Neuro about it when I see him again next month but I thought I'd find out what I could in the mean time. I searched the internet and didn't come up with much and the PSP Association on this Web Site was not helpful. Maybe I'm just being paranoid but with so many of the people here being able to do things that I no longer can I can't help but wonder......AND if anyone says to me just take baby steps I'll........ well I don't know what I will do but it would not be appreciated.
