Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is an incurable and invariably fatal neurodegenerative disease of cattle. [2] Symptoms include abnormal behavior, trouble walking, and weight loss. [1] Later in the course of the disease, the cow becomes unable to function normally. [1]
BSE is a degenerative infection of the central nervous system in cattle. It is a fatal disease, similar to scrapie in sheep and goats, caused by a prion.A major epizootic affected the UK, and to a lesser extent a number of other countries, between 1986 and the 2000s, infecting more than 190,000 animals, not counting those that remained undiagnosed.
In the 1980s and 1990s, bovine spongiform encephalopathy (BSE or "mad cow disease") spread in cattle at an epidemic rate. The total estimated number of cattle infected was approximately 750,000 between 1980 and 1996. This occurred because the cattle were fed processed remains of other cattle.

For example, prion diseases, all of which cause transmissible spongiform encephalopathies , are invariably fatal, but other encephalopathies are reversible and can have a number of causes including ...
Average life expectancy following the onset of symptoms is 13 months. [1] It is caused by prions, which are misfolded proteins. [9] Spread is believed to be primarily due to eating beef infected with bovine spongiform encephalopathy (BSE). [7] [9] Infection is also believed to require a specific genetic susceptibility.
