An erythematous skin rash subsequently developed and Sydenham{\textquoteright}s chorea (SC) was diagnosed. Following neuroleptic medication and steroids, her chorea and psychosis subsided. This case illustrates that severe psychotic features can occur in SC. It is recommended that antistreptolysin O titres and antibasal ganglia antibodies are checked early in patients with evolving movement disorders and prominent neuropsychiatric features, as the window for modifying the course of this immune-mediated disorder may be narrow.}, issn = {1470-2118}, URL = {https://www.rcpjournals.org/content/9/2/188}, eprint = {https://www.rcpjournals.org/content/9/2/188.full.pdf}, journal = {Clinical Medicine} }
