A81.1: Subacute sclerosing panencephalitis

You have a disease of the brain that is caused by viruses.

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.

You have been infected with measles viruses in the past. In the course of this, you have a skin rash and fever, for example.

The measles viruses have caused an inflammation in your brain. This usually only occurs after several years. The disease causes a change in behavior. You may have difficulties concentrating. The muscles throughout your body may twitch. Furthermore, you may lose consciousness.

This disease makes you severely ill.
