Ataxia
Pronunciation: ah-TAK-see-ah
Lack of muscle coordination resulting in irregular, unsteady movements and impaired balance.
Full Definition
Ataxia is a neurological condition characterized by lack of muscle coordination, resulting in irregular and unsteady movements. It affects gait, balance, speech, and fine motor skills. Ataxia can result from damage to the cerebellum, brainstem, or peripheral nerves, and is commonly seen in rehabilitation patients following stroke, traumatic brain injury, multiple sclerosis, or alcohol-related brain damage. Treatment focuses on adaptive strategies, balance training, assistive devices, and speech therapy when speech is affected. The condition significantly impacts activities of daily living and mobility.
Usage
Usage note: Can be further specified by location (cerebellar ataxia, sensory ataxia) or cause.
