/What is Creutzfeldt-Jakob disease (CJD)?

CJD is a slow degenerative human disease of the central nervous system. It is classified as a transmissible spongiform encephalopathy because of the characteristic spongy degeneration of the brain that occurs as the disease progresses.

CJD occurs sporadically worldwide at a rate of 1 case per 1 million people per year.
