What is an example of a prion disease?
Prion diseases include bovine spongiform encephalopathy (BSE or “mad cow” disease) in cattle, Creutzfeldt-Jakob disease (CJD) and variant CJD in humans, scrapie in sheep, and chronic wasting disease (CWD) in deer, elk, moose and reindeer.
Why are prion diseases always fatal?
The functions of these normal prion proteins are still not completely understood. The abnormal folding of the prion proteins leads to brain damage and the characteristic signs and symptoms of the disease. Prion diseases are usually rapidly progressive and always fatal.

Is mad cow disease still around?
Can People Get BSE? People can get a version of BSE called variant Creutzfeldt-Jakob disease (vCJD). As of 2019, 232 people worldwide are known to have become sick with vCJD, and unfortunately, they all have died. It is thought that they got the disease from eating food made from cows sick with BSE.
How do prions work?
Prions cause neurodegenerative disease by aggregating extracellularly within the central nervous system to form plaques known as amyloids, which disrupt the normal tissue structure. This disruption is characterized by “holes” in the tissue with resultant spongy architecture due to the vacuole formation in the neurons.
