ICD-Code G31.0: Circumscribed brain atrophy
Certain areas of your brain have reduced in size.
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.
Various disorders can cause certain parts of the brain to get smaller. This involves the degeneration of brain tissue. The brain may also no longer be able to function properly in the affected areas. A range of symptoms may occur, depending on which areas of the brain are affected. For example, there may be changes in behavior. You may also have problems with other mental abilities. You may no longer be able to remember the right word for something. It is also possible to have other symptoms.
