a neurological disorder characterized by lack of coordination of voluntary muscle movements, which can affect gait, balance, speech, and other voluntary actions. It arises as a result of dysfunction of the cerebellum, which is responsible for coordination of movements. Ataxia can be caused by various factors such as genetic diseases, stroke, multiple sclerosis, or alcoholism. It often leads to unsteady movements, clumsiness, and difficulties performing tasks requiring fine motor skills.
