颈动脉内膜-中层厚度与认知功能障碍的关系

目的 探讨脑梗死患者颈动脉内膜-中层厚度（IMT）与认知功能障碍的关系.方法 选择96例脑梗死患者,采用彩色多普勒对颈动脉IMT进行测定,将研究对象分为两组：IMT＜1.0mm组和IMT≥1.0mm组,对两组的神经心理检查结果进行分析.结果 简易智能状态检查量表总分两组间比较无显著性差异.地点定向、时间定向、计算能力、短程记忆、书写能力、结构能力评分,IMT≥1.0mm组得分明显降低,两组间比较有显著性差异（P＜0.05）.结论 脑梗死患者IMT与血管性认知功能障碍存在密切的关系.

Relationship between intima-media thickness of carotid artery and cognitive impairment

Objective To investigate the relationship between the intima--media thickness （IMT） of carotid artery in patients with cerebral infarction and cognitive impairment. Methods Color Doppler ultrasonography was performed in 96 patients with cerebral infarction. 96 patients divided into two groups according to the carotid artery IMT, IMT〈1. 0 mm group and IMT≥1. 0 mm group. The level of the cognitive disorder in two groups was evaluated. Results There were no significant differences in the MMSE score between the two groups （P 〉 0.05）. The scores of orientatio for place, orientatio for time, calculation, short term memory, writing ability and structual organization in IMT≥1. 0mm group were lower than IMT（1.0ram group （P 〈0.05）. Conclusions There is close relationship between the intima--media thickness of carotid artery in patients with cerebral infarction and vascular cognitive impairment.
