Chorea

Chorea (sometimes called choreia) is the name for a set of symptoms caused by some neurological conditions.[1] The term "chorea" comes from Ancient Greek χορεία, where it means "dance". People with chorea move without being able to control those movements. The movements seem to spread from one muscle to the next. Chorea can involve the trunk, neck, face, tongue, and extremities.[2]

Chorea is one of the main symptoms of Huntington's disease.[3]

Some forms of chorea are not linked to neurological conditions, though. Chorea can develop as a complication of pregnancy, and it can be a sign of hyperthyroidism.[4] It can also be caused by drugs taken in the wrong dose.[4] For example, L-Dopa (taken to treat Parkinson's disease), certain forms of birth control, or certain antipsychotics can cause chorea if they are used in the wrong doses.
