Creutzfeldt-Jakob disease (CJD) is the most common human prion disease. Prion diseases are a group of rare brain and nervous system diseases that affect humans and some kinds of animals. Prion diseases are not caused by germs (i.e., viruses, bacteria). Instead, they are thought to result if normal brain proteins fold into abnormal forms.
