Chorea is chaotic, random, repetitive, purposeless movements that usually involve multiple body parts. Sydenham's chorea (SC) is the most common form of acquired chorea in children.

Key points

  • Sydenham's chorea (SC) is acquired after infection with a group A beta-hemolytic Streptococcus bacteria.
  • SC is often mild and usually goes away on its own after a few months. Most often, the movements do not need to be treated with medication or therapy.
  • It is very important to monitor cardiac function in children with SC because SC is associated with rheumatic fever, which can affect the heart.
  • Children with SC will require long-term antibiotic treatment to prevent recurrence of SC and to protect the heart.
