G13: Systemic atrophies primarily affecting central nervous system in diseases classified elsewhere

G13.0: Paraneoplastic neuromyopathy and neuropathy

Nerves are a sort of wiring in the body. Nerves conduct information. The nerves use electrical impulses to do this. Nerves are important, for instance, in enabling you to sense contacts and temperatures, and to move your muscles.

With this nerve disorder, the body's immune system attacks the nerves. The immune system normally protects the body against pathogens and foreign substances. With some disorders, however, parts of the immune system target the body's own tissue or cells. This can be the case with various cancers.

Depending on the nature of the condition, there may be a variety of symptoms. For example, the skin may feel numb or tingle. Walking or standing properly may become impossible. Depending on the nature of the condition, the muscles may also be affected. You can then have muscle weakness or muscle pain, for example.
