Disclosure: The authors report no conflicts of interest. Wild/Tabrizi 2 Introduction Chorea is a hyperkinetic movement disorder characterised by excessive spontaneous movements that are irregularly timed, randomly distributed and abrupt. It ranges in severity from restlessness with mild, intermittent exaggeration of gesture and expression, fidgety movements of the hands (seen online video) and unstable dance-like gait to a continuous flowing of disabling and violent movements. In this article we discuss the causes of chorea and an approach to its assessment. A brief history of chorea The term chorea is from the Greek koreia () meaning a dance. The word was first used medically by the alchemist Paracelsus (1493-1541) to describe Chorea Sancti Viti (St Vitus’ dance), which was probably an epidemic form of hysterical chorea occurring in the context of religious or superstitious fervour.1 Thomas Sydenham (1624-1689), studying St Vitus’ dance, identified a form of childhood chorea that now bears his name. One year after obtaining his medical qualification, George Huntington (1850-1916) in 1872 described a hereditary form of chorea “spoken of by those in whose veins the seeds of the disease are known to exist, with a kind of horror”, with onset in adult life and associated with cognitive and psychiatric manifestations.
