Explanation: 

Detailed explanation-1: -BSE also known as Mad Cow Disease is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. CWD is a prion disease that affects deer, elk and moose in some areas of North America, South Korea and Norway.

Detailed explanation-2: -Mad cow disease, or bovine spongiform encephalopathy (BSE), is a disease that was first found in cattle. It’s related to a disease in humans called variant Creutzfeldt-Jakob disease (vCJD). Both disorders are universally fatal brain diseases caused by a prion.

Detailed explanation-3: -"Bovine” means that the disease affects cows, “spongiform” refers to the way the brain from a sick cow looks spongy under a microscope, and “encephalopathy” indicates that it is a disease of the brain. BSE is commonly called “mad cow disease.”

Detailed explanation-4: -For reasons that are not yet understood, the normal prion protein changes into a pathogenic (harmful) form that then damages the central nervous system of cattle.

Detailed explanation-5: -Mad cow disease is a fatal disease that slowly destroys the brain and spinal cord (central nervous system) in cattle. It also is known as bovine spongiform encephalopathy, or BSE. People cannot get mad cow disease.
