The case histories are reported of six women who developed chorea while taking oral contraceptive drugs. The chorea that results from taking compounds containing oestrogen and progestogen has many features in common with chorea gravidarum, and the pathogenesis is probably similar. In some of the patients, however, the sudden onset of symptoms suggests a vascular aetiology.
