Sydenham Chorea is a neurological disorder that causes the involuntary movement of muscles in various parts of the body. The disorder usually affects children between the ages of five and fifteen.

In some cases, certain imaging techniques such as magnetic resonance imaging (MRI) may be recommended to exclude other causes. Usually, brain imaging is normal in Sydenham chorea. Of note, because the onset of Sydenham chorea usually occurs weeks after the infection, the characteristic signs of rheumatic fever or streptococcal infection are usually no longer present.
