目的观察中枢性眩晕患者局部脑血流量及脑血液动力学改变。
Objective To investigate the changes in regional cerebral blood flow (RCBF) and cerebral hemodynamics in patients with dizziness resulted from disorders of the central nervous system.
对中枢性眩晕病因、发病机理及出现以上TCD表现的原因进行了探讨。
The etiology of vertigo and the mechanism of changes in 3D-TCD are discussed in this paper.
结果中枢性眩晕患者60.5%出现脑血流量减少，伴相应动脉脑血流速度减低。
Result Decreased RCBF was found in 60.5% of the patients with also lowered cerebral blood flow velocity, and the abnormalities appeared more serious when the dizziness persisted.
目的：探讨脑干听觉诱发电位(BAEP)与前庭周围性眩晕和中枢性眩晕的相关性。
Objective: To explore the correlation between BAEP and vestibular peripheral and central vertigo.
结论：BAEP有助于前庭系统性眩晕的定位诊断，是鉴别前庭系统周围性与中枢性眩晕比较敏感的方法。
Conclusions: BAEP examination can be used for the location of the patient with vestibular system vertigo, and it's a more sensitive to distinguish between vestibular peripheral and central vertigo.
结论脑干听觉诱发电位能敏感的反映听觉脑干功能，可区别周围性、中枢性、混合性引起的眩晕。
Conclusion The brainstem auditory evoked potentials can sensitively reflect the brainstem auditory action, and can also distinguish the periphered, central and compound vertigo.
