Quizplus · Accepted Answer

The human form of mad-cow disease is known as variant Creutzfeldt-Jacob disease (vCJD). It is a fatal illness that is spread by consuming beef products infected with prions, abnormal proteins that can cause other proteins in the brain to misfold and create a chain reaction of damage. Huntington's disease and Parkinson's disease are neurodegenerative diseases that have different causes and symptoms than mad-cow disease. Vascular dementia is a form of dementia caused by impaired blood flow to the brain and is not related to prion diseases.
