G99: Other disorders of nervous system in diseases classified elsewhere

The group of conditions categorized as "Other disorders of the nervous system in diseases classified elsewhere" encompass a range of nervous system complications that are secondary manifestations of other diseases. These disorders impact the complex network of nerves and cells that transmit signals between different parts of the body, altering its normal function. People diagnosed under this group generally present symptoms connected to the nervous system, which may include difficulties with movement, balance, sensation, or other bodily functions. The specific symptoms, their severity, and progression will depend on the underlying disease causing these complications. These conditions could be the result of a variety of different diseases, including, but not limited to, systemic diseases, infections, or chronic conditions that damage or impair the nervous system's functionality. Understanding the primary disease causing the disorder is crucial in identifying the method of transmission and for focused disease management.
