Ataxia is a neurological condition characterized by a lack of voluntary coordination of muscle movements. It can affect various functions, including balance, speech, and eye movements. Ataxia can result from damage to the cerebellum, the part of the brain responsible for coordinating movement, or from other neurological disorders. There are different types of ataxia, including cerebellar ataxia and sensory ataxia, each with distinct causes and symptoms. Some forms are hereditary, while others may arise from conditions such as multiple sclerosis or stroke. Treatment often focuses on managing symptoms and improving quality of life.
