Hi Ray! It's in the nature of Prion Diseases to be progressive. They have alternatively been referred-to as "slow viruses". They often cause symptoms that at first can seem to be viral in nature but that then slowly and inexorably progress to the disadvantage of the host animal... With many of the developing symptoms being analogous to the symptoms of advancing Parkinsons Disease. Is that what you mean? :-) ATB, Bill ~~~~~~~~~~~~~~~~~~~~~~~~~ M.SchildAM.Schild -----Original Message----- From: Parkinson's Information Exchange Network [mailto:[log in to unmask]] On Behalf Of rayilynlee Sent: Wednesday, July 19, 2006 2:09 PM To: [log in to unmask] Subject: Re: H. pylori & viruses vs PD Bill, how does one account for the progressive nature of PD? ray ----- Original Message ----- From: "William P.

It might actually be caused by subunits of prions that are even smaller than prions per-se... fibrils, which are tiny chains of protein... There is increasing evidence that prions are much more prevalent than previously recognized. Prions are associated with many kinds of degenerative neurological diseases, both in humans and in animals. Does anyone have any further information on prions & PD?
