特发性震颤(essential tremor,ET)是一种慢性进行性疾病,核心症状表现为以上臂、手、头部和躯干等部位的4~12Hz姿势性或动作性震颤为特征。人群患病率为0.41%~3.92%[1]。长期以来,ET被认为是一种良性震颤,但是随着病情进展,患者身体的不自主震颤会严重影响其进食、说话、书写等一些日常活动,给患者造成较大的压力[2]。本文就近10年来ET的中西医研究进展作一综述。 Essential tremor (ET) is a chronic progressive disease characterized by 4 ~ 12Hz postural or behavioral tremor in the upper arms, hands, head and torso. The prevalence of the population was 0.41% ~ 3.92% [1]. ET has long been regarded as a benign tremor, but as the disease progresses, involuntary trembling of the patient’s body can seriously affect some daily activities such as eating, speaking and writing, putting more stress on the patient [2]. This article reviews the research progress of ET in recent 10 years.
