INTRODUCTION Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of animal and human brain diseases that are uniformly fatal and often characterized by a long incubation period and a multifocal neuropathologic picture of neuronal loss, spongiform changes, and astrogliosis (3). Investigators believe the etiologic agents of TSEs are abnormal conformers of a host-encoded cellular protein known as the prion protein. Prion diseases do not characteri...
