"These misfolded proteins have properties similar to prions, the researchers concluded. Prions are tiny, infectious protein particles can cause disease, such as mad cow disease which passes from infected cattle to humans through their meat.
In the study, the researchers removed brain tissue from mice with Alzheimer's-like symptoms, and injected into it into the stomach cavity of healthy mice. Four months later, the previously healthy mice showed symptoms similar to those of Alzheimer's disease and their brains had similarly disease brain tissue."
Mary, interesting article. I was joking earlier today that Alzheimer's Disease may be infectious since my wife worked with a man who was in the early stages of Alzheimer's. However, that was 56 years ago, so I doubt any relationship. But then prions can take a long time to become manifest.
With all the hormones and antibiotics they give cattle, chickens, etc. that we eat - who knows if the rise in AD could be related somehow. When those antibiotics in the meat enter our human systems who knows what it does to our bodies.
