G94.39: Unspecified encephalopathy in other disorders classified elsewhere

You have a brain malfunction.

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.

The brain may malfunction if, for example, salts or sugars are not present in the blood in the right quantities. Other disorders can also cause the brain to malfunction. When someone has a brain malfunction, they can feel confused or sleepy, for example. They may also find it harder to control their movements, or they may tremble violently.

In your case another disorder is the cause of the brain function disorder.
