ataxia

n. inability to coordinate muscular movement

Ataxia From Greek αν (used as a negative prefix) + τάξις (order), meaning "lack of order". It is a neurological sign and symptom consisting of gross incoordination of muscle movements. Ataxia is an aspecific clinical manifestation implying dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum. Several possible causes exist for these patterns of neurological dysfunction. The "International Ataxia Awareness Day" is celebrated on September 25th each year.
