Neuromuscular disorders affect your neuromuscular system. They can cause problems with:
- The nerves that control your muscles
- Your muscles
- Communication between your nerves and muscles
These disorders can cause your muscles to become weak and waste away. You may also have symptoms such as spasms, twitching, and pain.
Examples of neuromuscular disorders include:
- Amyotrophic lateral sclerosis
- Muscular dystrophy
- Myasthenia gravis
- Spinal muscular atrophy
There can be different causes for these diseases. Many of them are genetic.This means they are inherited (run in families) or are caused by a new mutation in your genes. Some neuromuscular disorders are autoimmune diseases. Sometimes the cause is unknown.
Many neuromuscular diseases have no cure. But treatments may improve symptoms, increase mobility, and lengthen life.

 Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
