Abstract
Transmissible spongiform encephalopathies (TSEs) or prion diseases are group of rare and rapidly progressive fatal neurologic diseases. The agents responsible for human prion diseases are abnormal proteins or prion that can trigger chain reactions causing normal proteins in the brain to change to the abnormal protein. These abnormal proteins are resistant to enzymatic breakdown, and they accumulate in the brain, leading to damage. TSEs have long incubation periods followed by chronic neurological disease and fatal outcomes, have similar pathology limited to the CNS including convulsions, dementia, ataxia, and behavioral or personality changes, and are experimentally transmissible to some other species.
