Sydenham's chorea: not gone but perhaps forgotten.

Sydenham's chorea (SC) is characterised by chorea, emotional lability and hypotonia. In this study, we investigated the incidence and clinical presentation of childhood SC in Ireland (years 2006-2014). Nineteen cases were diagnosed. Five patients had rheumatic fever. An increasing trend with an incidence of 0.23/100 000 is reported. As most referral diagnoses included psychogenic illness, head injury and stroke, modern physicians may not be aware of this age old illness. A review of the manifestations and diagnosis of SC is presented. Published by the BMJ Publishing Group Limited.
