Also called: CJD

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative brain disorder. Symptoms usually start around age 60. Memory problems, behavior changes, vision problems and poor muscle coordination progress quickly to dementia, coma and death. Most patients die within a year.

The three main categories of CJD are

  • sporadic CJD, which occurs for no known reason
  • hereditary CJD, which runs in families
  • acquired CJD, which occurs from contact with infected tissue, usually during a medical procedure

Cattle can get a disease related to CJD called bovine spongiform encephalopathy (BSE) or "mad cow disease." It is possible that people can get a variant of CJD from eating beef from an infected animal.
