A81.0: Creutzfeldt-Jakob disease

You have a brain disorder caused by altered proteins.

The brain is made up of several areas. For example, the cerebrum is used to think and plan actions. In the cerebellum, movements are initialized and coordinated. The brain stem is responsible for various unconscious tasks such as breathing. The brain stem passes into the spinal cord.

Your brain has been severely damaged by altered proteins. The cause of the disease is usually unknown. Sometimes the disease is also hereditary. In that case, several family members are often affected by it. But the proteins can also get into the body via food from cattle.

The altered proteins also damage the normal proteins in the brain. As a result, more and more proteins in the brain are changed. If altered proteins accumulate in the brain, the brain’s nerve cells die off. This often results in abnormal behavior. The memory and concentration often rapidly decline. In that case, you may no longer be able to control specific movements.

This disease makes you severely ill.

Additional indicator
