目的：探讨老年人眩晕与脑血管缺血的关系。方法：综合分析老年眩晕１１０例的ＥＮＧ、ＴＣＤ及眼底动脉硬化程度。结果：１１０例中前庭功能减退占２７．３％，ＥＴ Ⅱ型以上曲线占８０．９％，ＯＫＮ不对称占５９．１％，ＴＣＤ显示９０％的患者脑血管缺血，眼底动脉硬化占９７．３％，耳聋占８８．２％。结论： 老年人眩晕不能以某一特定的诊断作为终结，应该多因素综合考虑老年人生理性退行性变。脑血管缺血性改变是引致老年人眩晕的重要因素。
Objective: To investigate the relationship between dizziness and cerebrovascular ischemia in the elderly. Methods: A comprehensive analysis of 110 cases of senile vertigo ENG, TCD and fundus arteriosclerosis degree. Results: The decrease of vestibular function in 110 cases accounted for 27.3%, the curve of ET Ⅱ type accounted for 80.9%, the percentage of OKN asymmetry was 59.1%, and TCD showed cerebral ischemia in 90% of the patients. The rate of fundus arteriosclerosis was 97 .3%, deafness accounted for 88.2%. Conclusion: Vertigo in the elderly can not be terminated by a specific diagnosis. Physiological degenerative changes should be considered in the elderly with multiple factors. Cerebral ischemia is an important factor that causes dizziness in the elderly.
