To document possible changing characteristics of Sydenham chorea, we reviewed records of 240 patients with this diagnosis who were seen between 1951 and 1976. A dramatic progressive decline in the number of cases was observed. The syndrome occurred mainly in childhood. Female predominance was apparent only after age 10. There was a high familial incidence for both chorea and rheumatic fever. Most patients had generalized chorea, and fewer than 20% had hemichorea. Dysarthria, probably of…

Sydenham chorea: a case report and review of the literature.
TLDR
The case of a 9-year-old girl withydenham chorea, the most common acquired chorea in children, is described and a discussion of the pathophysiology, clinical presentation, and management of SC in the emergency department follows.
Sydenham chorea: MR manifestations in two cases.
TLDR
The MR manifestations of two clinically corroborated cases of Sydenham chorea correlated with anatomic regions, which have been described to be susceptible to cross reaction with lgG antibodies that are formed in association with streptococcal infection.

Cerebral Vasculitis in a Case of Sydenham's Chorea
TLDR
A 10-year-old girl with acute-onset hemichorea had multiple areas of abnormal signal seen on magnetic resonance imaging of the brain, associated with middle and anterior cerebral artery vasculitis seen on cerebral angiography, the first report of abnormal cerebralAngiography in Sydenham's chorea.
Sydenham chorea in children
TLDR
There have been no adequate, double-blind, randomized studies to evaluate the symptomatic treatment of Sydenham chorea, and proposed treatment options and dosing strategies are reviewed.
Hemichorea as a presentation of acute rheumatic fever.

TLDR
Because at least 20% of patients with SC experience recurrent attacks of ARF, they carry a high risk of developing severe cardiac lesions, and these patients require prophylaxis against streptococcus infection, using penicillin or sulfa drugs.
Recurrence of Sydenham chorea: implications for pathogenesis.
TLDR
In a significant subgroup of patients, SC recurrence might not be a true relapse of rheumatic fever and might represent either a primary underlying abnormality that renders patients susceptible to developing such a movement disorder or the outcome of permanent subclinical damage to the basal ganglia following the initial SC episode.

TLDR
The data would suggest that uncomplicated Sydenham's chorea is not necessarily a benign self-limited affliction of the central nervous system and that some patients are left with definite, albeit minimal, neurologic residua.
ELECTROENCEPHALOGRAM IN SYDENHAM'S CHOREA.
TLDR
The present study was undertaken to explore further the possible value of the electroencephalogram in the diagnosis of Sydenham's chorea and found its incidence and character have been inconsistent and authors have differed in their interpretations of the findings.

TLDR
It is now well established that rheumatic polyarthritis and carditis occur one to five weeks after infections of the throat due to the Group A streptococcus, and this theory was confirmed by the reduction in the recurrence rate of rhematic fever achieved through antistreptococcal prophylaxis.
A psychosomatic study of eight children with Sydenham's chorea.
TLDR
It is felt that Sydenham's chorea can be understood only as a psychosomatic illness potentially caused by a number of agents acting individually or jointly, and varying in their respective importance from case to case.

TLDR
The benign nature of uncomplicated chorea is stressed, the disappearance of physical signs of heart disease in some patients is contrasted with the delayed and even remote appearance of valvular deformity in others, and the favorable course to date in the majority of cases is emphasized.
Chorea induced by oral contraceptives
TLDR
Patients with preexisting striatal abnormalities appear more susceptible to oral contraceptive-induced chorea which is reversible on drug discontinuation, but clinical and experimental data suggest that it involves altered central dopaminergic activity.
