The literal meaning of the word ataxia is without coordination.
Those affected with this disease have problems related to coordination, as the segments of nervous system controlling the movement and balance are damaged. Ataxia may affect the fingers, hands, arms, legs, body, speech, and eye movements.
The medical history, family history, and a complete neurological evaluation that includes MRI scan of the brain are required for the diagnosis of ataxia. However, the type of ataxia is generally confirmed by DNA test.
