G31: Other degenerative diseases of nervous system, not elsewhere classified
G31.8: Other specified degenerative diseases of nervous system
G31.8 refers to other specified degenerative diseases of the nervous system. These are conditions that cause the progressive deterioration and loss of function in nerve cells, which control various functions in your body like movement and cognition. The exact type and severity of symptoms will vary greatly depending on the specific disease, but common signs often include difficulties with movement (such as tremors or stiffness), memory problems, behavioral changes, and other cognitive difficulties. These conditions are generally caused by a combination of genetic, environmental, and lifestyle factors. Unfortunately, because these diseases lead to permanent, progressive damage to the nervous system, they typically worsen over time. This can often lead to significant disability and may impact a person’s ability to perform everyday tasks independently.
