What is Creutzfeldt-Jakob disease (CJD)?

ANSWER

Creutzfeldt-Jakob Disease (CJD) is a rare form of dementia that happens when a protein -- called a prion -- folds into an abnormal shape, and other prions start to do the same. This damages brain cells and triggers a fast mental decline.

People with CJD also have mood changes, confusion, twitchy or jerky movements, and trouble walking. Sometimes, the disease is passed down through families, but it also can happen for no known reason. One type, called variant CJD (or mad cow disease, also known as bovine spongiform encephalopathy), has spread from cattle to people in certain situations.
