G13: Systemic atrophies primarily affecting central nervous system in diseases classified elsewhere
G13.2: Systemic atrophy primarily affecting central nervous system in myxoedema
The nervous system includes all the nerves in the body, as well as the brain and the spinal cord. The nerves run from the brain and spinal cord into the body. They convey information in the body. The brain is located inside the head. It receives, processes and stores sensory impressions. The brain controls movements and various physical functions.
The thyroid is a small organ at the bottom of the neck. The thyroid gland needs iodine to produce important messenger substances for the body. These messenger substances influence the heartbeat, digestion, and body temperature, among other things. If the thyroid gland stops working properly, the nervous system may also be affected.
There can be a variety of symptoms, depending on exactly which parts of the nervous system are affected. If the brain is affected one's mood, thoughts and behavior can change, for example. You may also have problems with your memory or concentration. It may also become impossible to control your movements properly.
