摘要：

目的研究血清胰岛素样生长因子-1(IGF-1)水平与脑卒中后痴呆(post-stroke dementia,PSD)的关系。方法同期选择脑卒中患者129例作为脑卒中组,其他疾病患者76例为对照组,健康老年人41例为正常组。6个月后将脑卒中组患者按其是否符合痴呆诊断标准又分为PSD组(65例)和非PSD组(64例),发病时及6个月后测血IGF-1及认知功能量表测定。结果脑卒中组IGF-1水平比对照组低,差异无显著性意义(t=-1.88,P=0.06),与正常组比较,则差异有显著性意义(t=-2.79,P=0.006);PSD组IGF-1水平比其他3组均低,4组间组内比较,差异有显著性意义(F=3.43,P=0.013);发病6个月后,PSD组IGF-1保持较低水平;logistic回归方程发现与PSD相关的危险因素包括年龄、收缩压I、GF-1及冠心病、高血压。相关分析发现血IGF-1水平与一般认知功能水平相关,其中空间结构能力、注意、短时记忆与瞬间记忆受影响比较明显(P<0.05)。结论脑卒中发病时低IGF-1水平者,其发生PSD的可能性大;血IGF-1水平与认知功能存在一定的相关性。
