【摘要】 目的:探讨原发性震颤(ET)的临床和家系特点。方法:回顾2例原发性震颤患者的临床特点和家族史。结果:ET先证者均表现为意向性震颤,饮酒后减轻。两家系一级、二级亲属患病率分别为55.6%和43.7%,β受体阻滞剂普奈洛尔(心得安)治疗有效。结论:ET的临床表现以姿势性或意向性震颤为主,手及头部受累明显,多数患者饮酒试验阳性,大多数ET患者具有家族遗传性。更多还原

【Abstract】 Objective: To investigate the clinical and familial characteristics of essential tremor(ET).Methods: The clinical features and familial history of 2 ET patients were reviewed.Results: The clinical manifestation of the probands was intentional tremor,which could be ameliorated by alcohol.The incidence of the disease was 55.6% and 43.7% among the first-and second-degree relatives of the two families.Propranolol,a β-adrenoceptor antagonist,was an effective drug for ET.Conclusion: Clinically ET is characterized by postural or intentional tremor,which mostly involves the hands and head.Positive result of the alcohol test is shown in most ET patients.It is commonly assumed to be a genetic disease.更多还原
