We describe a thyrotoxic patient with choreic movements. The latter gradually receded and disappeared as the patient was treated with methimazole and β‐adrenoceptor blocker, and the improvement deteriorated during a β‐adrenoceptor challenge test. Our findings suggest that the pathogenesis of thyrotoxic chorea seems more likely to be of biochemical origin rather than due to structural changes in the basal ganglia. © 2003 Movement Disorder Society
