Sydenham's chorea results from childhood infection with Group A beta-haemolytic Streptococcus and is reported to occur in 20–30% of people with acute rheumatic fever. The disease is usuall…
Streptococcus
Streptococcus is a genus of gram-positive coccus or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales, in the phylum Firmicutes. Cell division in streptococci occurs along a single axis, so as they grow, they tend to form pairs or chains that may appear bent or twisted.

Overview Of Rheumatic Chorea
Rheumatic Chorea is also commonly used with the term Sydenham Chorea. Sydenham chorea is a movement disorder that occurs after infection with certain bacteria called group A streptococcus.
Commonly Associated With
St. Vitus dance; Chorea minor; Rheumatic chorea; Rheumatic fever – Sydenham chorea; Strep throat – Sydenham chorea; Streptococcal – Sydenham chorea; Streptococcus – Sydenham chorea
Causes Of Rheumatic Chorea
Sydenham chorea is caused by an infection with bacteria called group A streptococcus. This is the bacteria that cause rheumatic fever (RF) and strep throat. Group A streptococcus bacteria can react with a part of the brain called basal ganglia to cause this disorder. The basal ganglia are a set of structures deep in the brain.
Symptoms Of Rheumatic Chorea
Sydenham chorea mainly involves jerky, uncontrollable, and purposeless movements of the hands, arms, shoulder, face, legs, and trunk. These movements look like twitches and disappear during sleep.
Exams & Tests
The health care provider will perform a physical exam for rheumatic chorea. Detailed questions will be asked about the symptoms.
Treatment Of Rheumatic Chorea
Antibiotics are used to kill the streptococcus bacteria. The provider may also prescribe antibiotics to prevent future RF infections. This is called preventive antibiotics, or antibiotic prophylaxis.
