Mad cow disease, or bovine spongiform encephalopathy (BSE), is a transmissible, slowly progressive, degenerative, and fatal disease affecting the central nervous system of adult cattle. The U.S. Department of Agriculture (USDA) has tested hundreds of thousands of cattle for BSE.
The disease is believed to have a long incubation period, of many years, but is ultimately fatal. A rare and fatal brain disorder called multiple system atrophy (MSA) may be caused by a newly discovered prion, a protein similar to the ones that cause mad cow and Creutzfeldt-Jakob disease (CJD), according to a new study.
