Choreoathetosis is the occurrence of involuntary movements in a combination of chorea (irregular migrating contractions) and athetosis (twisting and writhing).

It is caused by many different diseases and agents. It is a symptom of several diseases, including GLUT1 deficiency syndrome, Lesch–Nyhan syndrome, phenylketonuria, and Huntington disease and can be a feature of kernicterus (rapidly increasing unconjugated bilirubin that cross the blood-brain-barrier in infants).
