Chorea

(ko-rē'ah.) [From Gr. choros, a dance.] (Med.) A disease which manifests itself in convulsive motions of the limbs, face, head, and trunk, and very commonly called St. Vitus's Dance. It is most common in early life, from 10 or 12 till puberty. The early stages should be attentively watched, and great care should be taken in the cure, lest relics of it should be retained through life. The proper mode of treatment is by tonics, nourishing aliment, and plenty of open-air exercise. [s. 183]
