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 Lesch-Nyhan syndrome, phenylketonuria, and Huntington disease and can be a feature of kernicterus (rapidly increasing uncongucated billirubin that cross the blood-brain-barrier in infants).

Choreoathetosis is also a common presentation of dyskinesia as a side effect of levodopa-carbidopa in the treatment of Parkinson disease.[1]
