飞行人员慢性主观性头晕临床诊治研究进展

Advances in diagnosis and treatment of chronic subjective dizziness in pilots

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平衡感,同时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差,不伴有前庭功能疾病。CSD的概念由Staab和Ruckenstein在2004-2005年首次提出,反应了精神因素与神经科-耳科疾病之间的紧密联系,并且他们力图确定病因、诊断标准和治疗方法。因飞行人员工作压力大,易产生焦虑症状,可表现为慢性头晕,从而引起飞行信心不足,进而影响飞行。本文就CSD的病因、发病机制、临床表现、诊断与治疗及其新概念和新方法进行全面阐述。

Chronic subjective dizziness （CSD） refers to a chronic non-rotational dizziness or a subjective imbalance accompanied by hypersensitivity to motion stimuli and poor tolerance for complex visual stimuli or precision visual tasks, occurring in the absence of active vestibular deficits. The concept of CSD, first introduced by Staab and Ruckenstein in 2004-2005, describes the relationship between psychological factors and other neuro-otologic disorders. They endeavore to provide its etiologies, diagnostic criteria and treatment strategy. Pilots are prone to anxiety symptoms manifested as chronic dizziness due to work pressure, which can cause lack of flight confidence then affecting them in flight. Following is a review of the etiology, pathogenesis, clinical manifestation, diagnosis and treatments of CSD.
