摘要： 特发性震颤是以姿势性或动作性震颤为主要表现的运动障碍性疾病，也是临床最为常见的神经系统疾病之一。传统观点认为，特发性震颤是一种单一症状的良性运动障碍性疾病，近年来，相关研究表明其亦可表现出非运动症状。对特发性震颤非运动症状的研究和探索，为临床诊断与治疗以及疾病机制的研究提供了新视角。

Abstract: Essential tremor (ET), a movement disorder characterized by postural or kinetic tremor as the main clinical manifestations, is one of the most common neurological diseases. Traditional view contends that essential tremor is a benign movement disorder with merely motor symptoms. Recent researches show that patients may have some non-motor symptoms besides motor symptoms. Researches and exploration on its non-motor symptoms provide us with a new perspective for clinical diagnosis, treatment and better understanding of the disease.
