Sydenham chorea is a rare neurological disorder characterized by rapid, involuntary, purposeless movements, especially of the face, feet and hands. Additional symptoms may include muscle weakness and emotional or behavioral problems. Sydenham chorea most often affects children and adolescents. Sydenham chorea usually develops following Streptococcal infection and may occur as an isolated finding or as a major complication of acute rheumatic fever. The movement disorder is considered an autoimmune disorder, meaning it occurs when the body's immune system (which normally responds to a foreign substance) mistakenly attacks healthy tissue.
