The term chorea is derived from Ancient Greek χορεία (choreia) 'dance', as the movements of the body is comparable to dancing.The condition was formerly called Huntington's chorea but was renamed because of the important non-choreic features including cognitive decline and behavioural change.It is increasingly rare, which may be partially due to penicillin, improved social conditions, and/or a natural reduction in the bacteria (Streptococcus) it has stemmed from.The broader spectrum of paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection can cause chorea and are collectively referred to as PANDAS.[2] Other acquired causes include CSF leak,[3] systemic lupus erythematosus, antiphospholipid syndrome, thyrotoxicosis, polycythaemia rubra vera,[2] transmissible spongiform encephalopathies, coeliac disease[4] and gluten ataxia.
