We retrospectively evaluated the clinical and epidemiological characteristics of 100 patients suffering from Sydenham's chorea (SC). Our analysis revealed a recent, progressive decline in the number of new cases. Onset of SC was frequently reported between 7 and 12 years of age, being more frequent in females. Patients with generalized or severe chorea showed a higher risk of presenting gait abnormalities and behavioral symptoms. Chorea was transitory and remitted within the first 6 months in about 50% of patients but was persistent in 40%. Almost all patients with persistent chorea remitted after a protracted course of the disease.
我们回顾性评估了100例患有 Sydenham 舞蹈病（SC）患者的临床和流行病学特征。我们的分析显示，新发病例数量最近呈逐渐下降趋势。SC 的发病通常报告在7至12岁之间，女性更为常见。全身性或严重舞蹈病患者出现步态异常和行为症状的风险更高。舞蹈病是暂时的，约50%的患者在最初6个月内缓解，但40%的患者持续存在。几乎所有持续性舞蹈病患者在疾病病程延长后均缓解。
