G10-G14: Systemic atrophies primarily affecting the central nervous system
G11: Hereditary ataxia
Hereditary ataxia is a group of genetic disorders characterized by gradual loss of muscle control in the arms and legs, resulting in a lack of balance and coordination. These conditions are caused by mutated genes inherited from one or both parents. Common symptoms include poor coordination, unsteady walk and a tendency to stumble, difficulty with fine motor tasks, speech changes, and involuntary eye movements. With time, these symptoms may advance, often leading to a reliance on assistive devices such as wheelchairs. Hereditary ataxias primarily affect the nervous system, specifically the part of the brain responsible for coordinating movement, and may also involve other systems of the body. Despite the many forms of hereditary ataxia, they generally share the theme of progressive balance and coordination difficulties that can impact daily activities.
