Etymology

Origin of ataxia

First recorded in 1605–15; from New Latin, from Greek: “indiscipline,” from a- a- 6 + táx(is) -taxis + -ia -ia


Explanation

Ataxia is a medical condition that causes people's muscles to move involuntarily. Having trouble balancing can sometimes be a sign of ataxia. If you suffer from ataxia, your muscles have stopped working together normally — you're not able to coordinate your movements the way you want to. Ataxia is a disorder of the nervous system that can be caused by many different conditions, including vitamin deficiency and inherited illnesses. In medical Latin, ataxia is "confusion or disorder," from the Greek taxis, "arrangement or order."
