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.
