I was reading an article on neurodegenerative disorders and was alarmed because it was the first time I had heard about an infectious agent - prions - possibly causing the epidemic in neurodegenerative disorders such as Alzheimer's, Parkinson's, MSA, and Creutzfeldt-Jakob that countries such as the USA, Finland, and Iceland are experiencing. “There is now real evidence of the potential transmissibility of Alzheimer’s,” says Thomas Wiesniewski M.D. a prion and Alzheimer’s researcher at New York University School of Medicine. “In fact, this ability to transmit an abnormal conformation is probably a universal property of amyloid-forming proteins (prions).” (Source: "Alzheimer’s Disease Spreading Through Bodily Fluids" by Gary Chandler alzheimerdisease.tv) A statistic cited was that spouses of people with Alzheimer's are 600-percent more likely to also contract the disease. The primary methods of prion transmission are urine, feces, blood, mucous, and saliva. It made me think that there may be a connection between my deceased MIL's MSA and my FIL's cognitive downward spiral.
