G90-G99: Other disorders of the nervous system

G96: Other disorders of central nervous system

The G96 group entails various disorders of the central nervous system, a key part of the body controlling most functions and activities. These disorders can be marked by an array of symptoms, depending on their nature and the specific region of the central nervous system involved. Symptoms commonly observed include headaches, muscle weakness, impaired coordination, memory loss, and changes in sensation or perception. Disorders in this group can arise from several causes such as injuries, infections, genetic susceptibility, environmental factors, and other medical conditions like autoimmune diseases. Progression varies widely from conditions that are slowly degenerative, causing gradual deterioration of function, to those that remain relatively stable or even potentially reversible. The systems affected can vary from motor and sensory systems to cognitive and emotional functions, following the broad influence of the central nervous system.
