Noun: A fatal, transmissible neurological disease affecting deer, elk, moose, and related animals (cervids). It belongs to the group of diseases known as transmissible spongiform encephalopathies (TSEs), which are characterized by brain damage leading to microscopic holes giving the brain a sponge-like appearance. The disease is caused by abnormal, infectious proteins called prions.
