A 52‐year‐old man with a history of cerebrovascular disease presented with a 3‐year history of paroxysmal hemidystonia precipitated by assuming an upright position after sitting or lying down. MRA showed occlusion of the contralateral internal carotid artery (ICA) and near‐total occlusion of the ipsilateral ICA. Subtraction single proton emission computed tomography demonstrated decreased perfusion in the contralateral frontoparietal cortex during the typical dystonic spell. We have coined the term “orthostatic paroxysmal dystonia” for this phenomenon. © 2002 Movement Disorder Society
