Chorea gravidarum simply denotes the occurrence of chorea during pregnancy and has multiple underlying causes. Causes include past episodes of Sydenham chorea, rheumatic fever, estrogen-based oral contraceptive use, and systemic lupus erythematosus (SLE).
Most cases of chorea gravidarum occur during a first pregnancy. More than half of affected patients have a previous history of chorea. Symptoms may recur during subsequent pregnancies depending on the underlying cause.
Treatment can include addressing the underlying cause or use of antipsychotics and antiepileptics. Chorea gravidarum is often distressing, but not immediately harmful and requiring of treatment.
