头晕是由许多不同的病理生理机制引起的非特异性症状。眩晕是一种运动错觉，表明前庭系统内存在病变。发作的持续时间和相关症状有助于确定病变部位和可能的诊断。对头晕患者的检查应包括仔细评估步态和平衡，以及寻找自发性和位置性眼球震颤。前庭眼反射可以在床边通过娃娃眼、动态视力和冰水热量测试进行定性评估。每个测试提供有关前庭功能的不同信息。
Dizziness is a nonspecific symptom caused by many different pathophysiologic mechanisms. Vertigo, an illusion of movement, indicates a lesion within the vestibular system. The duration of attacks and associated symptoms helps to determine the site of lesion and likely diagnosis. Examination of the dizzy patient should include a careful assessment of gait and balance and a search for spontaneous and positional nystagmus. The vestibulo-ocular reflex can be evaluated qualitatively at the bedside with the doll's eye, dynamic visual acuity, and ice water caloric tests. Each test provides different information about vestibular function.
