What Is Mad Cow Disease and Variant Creutzfeldt-Jakob Disease? Mad cow disease is an infectious disease caused by prions that affect the brains of cattle. The actual name of the disease is bovine spongiform encephalopathy (BSE), a name that refers to the changes seen in brain tissue of affected cows.
A human version of mad cow disease called variant Creutzfeldt-Jakob disease (vCJD) is believed to be caused by eating beef products contaminated with central nervous system tissue, such as brain and spinal cord, from cattle infected with mad cow disease.t is not linked to eating nerve tissue from mad cow disease-affected cattle -- both vegetarians and meat eaters have died from classic CJD. CJD most commonly affects people over 65 and is usually fatal within six months from onset of symptoms. 1 | 2 | 3.
