Left-sided Post-hemiplegic Choreoathetosis

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 unconjugated 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]

The use of crack cocaine or amphetamines can result in conditions nicknamed crack dancing, or tweaking respectively, described as choreathetoid.[2]
