Forms of these diseases:

These disease became more well known when Mad Cow Disease and Chronic Wasting Disease became more of an epidemic in cattle and deer in the UK and America. BSE/Mad Cow probably originated by feeding cattle meat/bone meal that contained BSE infected products from spontaneously occuring cases.

-Destruction of surgical tools used on the brain or nervous tissue.
-Restrictions on food supply, especially cattle.
-Vaccines and Insulin are monitored
-No cure for Prion diseases, only treatments for some symptoms, and most drugs are experimental.
-Quinacrine reduces growth of abnormal prion proteins.
-Pentosan Polysuphate (PPS) delays onset of prion diseases.
-Some medications can be used to aid with behavioral or sleep disturbances.
