pregnancy. If left untreated, the disease resolves in 30% of patients before delivery but, in the other 70%, it persists. The symptoms then progressively disappear in the next few days following the delivery. Chorea may also be caused by drugs (commonly levodopa, anti-convulsants and anti-psychotics). Other acquired causes include CSF leak, systemic lupus erythematosus, antiphospholipid syndrome, kappa light-chain monoclonal gammopathy of undetermined significance, thyrotoxicosis, polycythaemia rubra vera, transmissible spongiform encephalopathies, coeliac disease and gluten ataxia. Treatment There is no standard course of treatment for chorea. Treatment depends on the type of chorea and the associated disease. Although there are many drugs that can control it, no cure has yet been identified. History Historically, choreas like Huntington disease and Sydenham's chorea were called Saint Vitus' dance, related to a series of social phenomena of the same name.
