摘　　要：目的通过研究焦虑症伴头晕患者及单纯头晕患者卧立位脑血流调节变化,明确焦虑症对头晕患者脑血流调节的影响并探讨其作用机制。方法分别选取焦虑症伴头晕患者及单纯头晕患者各20例,检测两组患者卧立位血压及卧立位脑血流。结果两组患者卧立位血压变化比较无统计学差异,单纯头晕患者脑血流在立位后2m in内可恢复到正常水平,而焦虑症伴头晕患者脑血流不能恢复到正常水平。结论焦虑症伴头晕患者脑血流调节异常是由焦虑状态引起的,这种脑血流调节异常可能是导致患者头晕症状出现的主要原因。Objective To analyze the difference of cerebral blood flow autoregulation in dizzy patients associated with /without anxiety and explore the possible pathogenesis.Methods The supine-standing cerebral blood flow curves of middle cerebral artery were analyzed in 20 dizzy patients with anxiety and other 20 without anxiety using TCD.Results Compared with dizzy patients without anxiety,the cerebral blood flow（CBF） significantly decreased in patients with anxiety disorder following standing up in 2min.Conclusions The cerebral blood flow autoregulation were decreased in patients with dizziness associated with anxiety,which may be secondary to anxiety disorders and may lead to dizziness.
