慢性主观性头晕

Chronic Subjective Dizziness

慢性主观性头晕(chronic subjective dizziness,CSD)指一种慢性非旋转性头晕或主观不稳感,患者对运动刺激高度敏感,对复杂视觉刺激或精细视觉任务耐受性差,不伴有活动性前庭功能障碍。CSD的概念由Staab和Ruckenstein在2004-2005年首次提出,反映了精神因素与神经科-耳科疾病之间的紧密联系,可分为神经-耳源性、心因性、交互性三种类型。CSD的治疗包括药物、心理治疗、前庭康复训练和认知行为治疗。本文将就CSD的病因、发病机制、临床表现、诊断与治疗进行全面阐述。

Chronic subjective dizziness（CSD） is defined as a syndrome of chronic nonvertiginous dizziness or subjective imbalance accompanied by hypersensitivity to motion stimuli and poor tolerance for complex visual stimuli or precision visual tasks, all occurring in the absence of active vestibular deficits. Staab and Ruckenstein introduced this concept for the first time in 2004-2005 which reflected the relationship of psychological factors and other neuro- otologic disorders and it included three types（nerve-otologic, psychogenic and interactive）. The treatments of CSD include medication, psychological therapy, vestibular rehabilitation and cognitive behavioral therapy. This article reviews the etiology, pathogenesis, clinical manifestations, diagnosis and treatments of CSD.
