This type of chorea has usually been considered a reactivation of Sydenham{\textquoteright}s chorea by an unknown mechanism. A patient developed a chorea triggered by the use of oral contraceptives with no definite evidence of previous Sydenham{\textquoteright}s chorea or recent streptoccocal infections. However, the patient had positive anti-basal ganglia antibodies, which supports an immunological basis for the pathophysiology of this chorea.}, issn = {0022-3050}, URL = {https://jnnp.bmj.com/content/75/2/327}, eprint = {https://jnnp.bmj.com/content/75/2/327.full.pdf}, journal = {Journal of Neurology, Neurosurgery \& Psychiatry} }
