Variant Creutzfeldt-Jakob Disease
Variant Creutzfeldt-Jakob disease (vCJD) is a fatal type of prion disease. Bovine spongiform encephalopathy (BSE) is a prion disease that affects cows. There is evidence that this illness can be transmitted to humans, producing vCJD. This illness is often called mad cow disease.
It is generally believed that vCJD is caused by infectious proteins called prions. Prions are normal proteins in the body. If these prions fold up in a different way than normal, they may transform into the protein that causes the illness. The build-up of abnormal prions may be linked to the brain damage associated with vCJD.
