Which movement disorder is most frequently seen in rheumatic fever?

The most frequently seen movement disorder in rheumatic fever is Sydenham chorea. This condition is characterized by rapid, unintentional, and involuntary movements, particularly affecting the face, hands, and feet. It is believed to result from an autoimmune response following a streptococcal infection, which is commonly associated with rheumatic fever. Sydenham chorea can occur several months after the initial infection, often manifesting in children and adolescents.

In the context of rheumatic fever, the presence of Sydenham chorea is notable because it is specifically linked to this condition as a major neurological complication. Understanding this association provides insight into the broader implications of rheumatic fever and highlights the importance of timely diagnosis and management of streptococcal infections to prevent such sequelae.

Other movement disorders, while they may present in various contexts, are not specifically linked to rheumatic fever in the same prominent manner as Sydenham chorea. This makes Sydenham chorea particularly important to recognize in the context of this disease.
