神经内科门诊685例老年眩晕患者的病因分析

Cause analysis of 685 cases of elderly vertigo in neurology clinic of outpatient department

目的:分析神经内科门诊以眩晕为主诉的老年患者的常见病因及临床特征。方法:685例老年眩晕患者均为同一时期神经科门诊患者,根据临床特点结合辅助检查,包括头部CT、脑血管超声、颈动脉超声检查、Dix-Hallpike试验、焦虑抑郁量表检测。分析确定眩晕病因。结果:685例老年眩晕患者病因及构成:后循环缺血性眩晕304例(44.4%),精神因素诱发眩晕187例(27.3%),不明原因的前庭周围性眩晕92例(13.4%),良性位置性眩晕81例(11.8%),其他原因占21例(3.1%)。结论:老年眩晕患者中,后循环缺血性眩晕为眩晕的常见病因,医师对有脑血管病危险因素的眩晕患者进行血管病因筛查尤为重要。

Objective： To study the common causes and clinical features of elderly patients with vertigo.Methods： The causes of vertigo were analyzed in 685 elderly neurological outpatients from Apr.2011 to Apr.2012 based on clinical features and laboratory examinationts including head CT,cerebral vascular ultrasound,carotid ultrasound,Dix-Hallpike test,anxiety and depression scale detection.Results： Among 685 cases of elderly patients with vertigo,304 cases（44.4%） were the posterior circulation ischemic rertigo,187 cases（27.3%） had mental factors that induced vertigo,92 cases（13.4%） had unexplained peniferal vestibular vertigo,81 cases（11.8%） had benign positional vertigo,and 21 casese（3.1%）had other causes.Conclusion：Posterior circulation is chemia vertigo is the common cause of vertigo in elderly patients.In vertigo patients with cerebro-vascular disease risk factors,the vascular causes should be screened.
