Vascular chorea in adults and children

摘要: Chorea may occur as part of the symptomatology acute stroke; it occasionally also be delayed or progressive. Patients with vascular-related chorea typically present an subacute onset one side body (hemichorea), contralateral to lesion. Cerebrovascular disease is most common cause sporadic chorea. Lesions are frequently found in thalamus and lentiform nucleus, less often subthalamic nucleus. The differential diagnosis choreic syndromes relies not so much on differences phenomenology hyperkinesia but age at onset, mode time course, family history, drug use, distribution body, presence accompanying neurological findings. Magnetic resonance imaging preferred demonstrate strategic small lesions regions that difficult image computed tomography, such globus pallidus, thalamus, Although prognosis hemichorea can benign, long-term specifically determined by stroke patients. Symptomatic treatment antichoreic drugs necessary phase. Surgery rarely indicated treat vascular
