    Chorea is a clinical syndrome characterized by abnormal involuntary arrhythmic movements, randomly distributed in time, affecting mainly the distal parts of the limbs. There are many diseases associated with chorea but the distribution of the etiologies vary too much in different parts of the world. We intended to study the etiologies of chorea in a Movement Disorders Unit of a university hospital-based outpatient clinic in Brazil. We studied the records of 119 patients with chorea based in the diagnostic criteria of the World Federation of Neurology. Sydenham's chorea (SC) was the most frequent cause of chorea (51.3%) of our sample. Other common causes were Huntington's chorea (18.5%) and chorea post-stroke (9.2%). SC is not commonly seen in developed countries nowadays but is not rare in Brazil. SC patients generally have the clinical manifestation of it in the first 20 years of age and girls are more affected than boys and this feature was observed in our sample. Based on our own experience and in the review of the literature we propose an etiological classification of chorea.
