Mad cow disease

A brain disorder in adult cattle that may be spread to humans through diseased meat.


Humans may acquire the disorder by eating diseased meat products. In humans, the disorder is called Creutzfeldt-Jakob disease (CJD). CJD ultimately leads to dementia and death. The condition is rare.


The disease is marked by rapid mental deterioration, usually within a few months. Most people eventually lapse into a coma.


Treatment focuses on keeping the person as comfortable as possible.
