How Mad Cow Disease Works? A cow gets BSE by eating feed contaminated with parts that came from another cow that was sick with BSE. The contaminated feed contains the abnormal prion, and a cow becomes infected with the abnormal prion when it eats the feed. If a cow gets BSE, it most likely ate the contaminated feed during its first year of life.
What causes mad cows disease? Mad cow disease is a progressive, fatal neurological disorder of cattle resulting from infection by a prion. It appears to be caused by contaminated cattle feed that contains the prion agent.
How is mad cow disease spread between humans? It’s spread by eating beef products from a cow that has been infected. Both animals and humans can get the disease. People get a version of BSE called variant Creutzfeldt-Jakob disease (vCJD).
How long can you live with mad cow disease? The disease can also cause brain damage and lead to psychotic behavior, dementia, and coma. Worst of all, there’s no cure for vCJD and people usually die within 13 months of showing symptoms. Furthermore, it can take up to 15 years for symptoms to manifest themselves.

Is there a test for mad cow disease in humans?
There is no single test to diagnose vCJD. Doctors may think that a person has vCJD based on where the person has lived and the person’s symptoms and past health. Imaging tests, such as an MRI , may be done to check for brain changes caused by vCJD. Researchers are now trying to develop a blood test that looks for vCJD.
How do you get CJD mad cow disease?
