G31: Other degenerative diseases of nervous system, not elsewhere classified

G31.2: Degeneration of nervous system due to alcohol

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. Many nerves run from the spinal cord and brain to the organs, skin and muscles in the body.

When someone drinks too much alcohol over a long period of time, the brain and nerves can become damaged. Depending on which area of the brain is damaged, one may have different symptoms. For example, one may have problems remembering events, or coping with everyday life. One may also no longer be able to walk properly.

When the nerves are damaged, one can also have various symptoms. For example, the skin in certain places may be numb or one may feel an unpleasant tingling. One may then have digestive problems or one’s pulse may be too fast or too slow.
