Prion diseases are a group of rare transmissible disorders characterized by progressive debilitating neurological manifestations due to spongiform changes with an invariably fatal course. The disorders all involve accumulation of an abnormal prion protein in the central nervous system with no specific immunological response. Sporadic Creutzfeldt-Jakob disease (CJD) is the most frequent form accounting for about 85% of prion disease cases. The other forms of prion disease are genetic (5-15%) and include inherited CJD, fatal familial insomnia (FFI), and Familial Alzheimer-like prion disease. Acquired forms (< 5%) include iatrogenic CJD and variant CJD (vCDJ).
