[Other chorea]
In addition to the above, symptomatic chorea-like involuntary movements may occur due to infectious diseases such as measles and diphtheria, pregnancy, carbon monoxide poisoning, systemic lupus erythematosus, and polycythemia. Chorea-like movements on one side may suddenly occur in middle-aged and elderly people due to vascular disorders in the basal ganglia, and this is called hemichorea.

*Some of the terminology that refers to "hemilateral chorea" is listed below.
