A neurological symptom characterized by major difficulties in muscular coordination. Ataxia is usually a sign of another condition that has yet to be unearthed (such as a damaged cerebellum). It can affect the way your eyes move, the way you speak and even your ability to swallow.
The condition could be caused by any of the following: abusing alcohol, having a stroke, a possible tumor, an inherited (defective) gene, the condition known as cerebral palsy and another condition, multiple sclerosis.
Example: A man is observed to walk with a broad-based gait, and to sway when standing. He is unable to stand on either foot unassisted.
