FAQ
Frequently Asked Questions
No, the chorea itself is not contagious. It is a complication of an infection (streptococcal), but the movement disorder results from the body's immune response, not direct transmission.
'Chorea' is a general term for a type of hyperkinetic movement disorder. 'Sydenham's chorea' is a specific, acquired form caused by rheumatic fever. Other causes include Huntington's disease or drug reactions.
It is exceedingly rare in adults. It is primarily a disease of childhood, typically occurring between ages 5 and 15. Adult-onset cases are usually recurrences of childhood illness.
Treatment focuses on eradicating the streptococcal infection with antibiotics, managing symptoms with medications like valproic acid or carbamazepine, and using immunomodulatory therapies (e.g., corticosteroids, IVIG) in severe cases.
