Creutzfeldt-Jakob disease (CJD) is a rare and ultimately fatal degenerative brain disease. It is one of a group of diseases called Transmissible Spongiform Encephalopathies (TSEs) that affect humans and animals. TSEs are thought to be caused by the build up of an abnormal form of the naturally occurring ‘prion’ protein in the brain.
Variant CJD is likely to be caused by consuming meat from a cow that has been infected with a similar prion disease called bovine spongiform encephalopathy (BSE), also known as ‘mad cow disease’.
Iatrogenic CJD is very rare, and occurs when CJD is accidentally transmitted as a result of medical or surgical exposures.
