Creutzfeldt-Jakob Disease (CJD)
What is it?
Creutzfeldt-Jakob Disease (CJD) is a human prion disease. It is a rare, degenerative, neurological disorder that presents with rapidly progressive dementia and eventually death. The disease is a part of a group called transmissible spongiform encephalopathies (TSEs). In these diseases a protein called prion is produced abnormally. CJD can be transmitted either sporadically or by inheritance- familial CJD. Also, a small number of patients can get contaminated with CJD after being exposed to infected human tissue such as corna or skin transplant., In the 1990s, some people in Britain developed a form of the disease after eating meat from diseased cattle. Risk factors for CJD include older age, familial history, exposure to contaminated tissue
