OBJECTIVE. Chorea is characterized by involuntary, fleeting, irregular, nonrhythmic movements that flow from 1 body region to another. There are many causes of childhood chorea, including cerebrovascular accidents, collagen vascular diseases, drug intoxication, hyperthyroidism, Wilson's disease, Huntington's disease, and infectious agents. Although Sydenham's chorea (SC), a nonsuppurative sequela of group A streptococcal infection, is known to be a common cause of chorea, multiple laboratory…

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.
Clinical and Neuroimaging Findings of Sydenham’s Chorea
TLDR
Nonspecific hyperintense white matter abnormalities may be due to the inflammatory process associated with a longer duration of clinical signs and to explain the MRI findings and the pathogenesis of SC, comprehensive studies are needed.
Sydenham's Chorea as Presentation of Rheumatic Heart Disease.
TLDR
A 13 years old girl who presented with weakness and purposeless involuntary movements of upper and lower limbs and had an unstable gait on walking which was aggravated during stress is described.

Sydenham's chorea.
TLDR
There was an increased incidence of Sydenham's chorea after 9 years of age in girls possibly suggesting the influence of female sex hormones and sodium valproate was effective in controlling the chorea.
Cardiac involvement in Sydenham's chorea: clinical and Doppler echocardiographic findings
TLDR
It is concluded that colour Doppler echocardiography may be useful in detecting silent valvular regurgitation and in deciding the duration of prophylaxis in patients with pure chorea.
Chorea in fifty consecutive patients with rheumatic fever
TLDR
Examining the prevalence and clinical features of Sydenham's chorea, a well‐recognized expression of RF, examined 50 consecutive patients with RF seen at the Pediatric Cardiology Clinic, finding that SC remains an important cause of chorea in countries plagued by RF.

Rheumatic chorea in northern Australia: a clinical and epidemiological study
TLDR
Differences in the patterns of chorea and other manifestations of acute rheumatic fever in different populations may hold clues to its pathogenesis and long term adherence to secondary prophylaxis is crucial to prevent recurrence.
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.
Sydenham's Chorea: a Case Showing Reversible Striatal Abnormalities on CT and MRI
TLDR
A case of Syndenham's chorea is described in which striatal abnormalities were found on both CT and MRL Repeat MRI when the patient's illness had resolved was virtually normal, suggesting that abnormal imaging is entirely compatible with a diagnosis of Sydnenham's choresa in a patient with an appropriate clinical history.
Chorea as a manifestation of rheumatic fever —A 30-year survey (1960–1990)
TLDR
Despite the recent dramatic decline in both incidence and severity of rheumatic fever in the authors' area, the frequency of carditis was unchanged and the incidence of chorea in the last three decades in this area was investigated retrospectively.
