Abstract
目的 探讨脑动脉狭窄与认知功能障碍之间的关系.方法 采用成人韦氏记忆测验(WMS)、成人韦氏智力量表(WAIS-RC)对72例脑动脉狭窄患者及18例健康者进行认知功能评估.结果 记忆商(MQ):椎-基底动脉狭窄组[(73.29±26.77)分]较颈内动脉狭窄组[(86.38±21.96)分]减退明显(P＜0.05),智商(IQ):颈内动脉狭窄组[(72.25±23.46)分]较椎-基底动脉狭窄组[(80.65±25.22)分]减退明显(P＜0.05).动脉狭窄各组的记忆功能和认知功能均较对照组差(P＜0.05),其中颈动脉狭窄组以领悟、算术、相似性、数字符号、填图、木块图等检测减退为主,椎-基底动脉狭窄组以背数、词汇、图形拼凑等检测减退为主(P＜0.01),而全脑动脉狭窄组的记忆认知功能减退是全面的.结论 脑动脉狭窄与认知功能密切相关,动脉狭窄类型不同,引起的认知功能障碍类型不同。
