摘要
目的 :探讨脑白质疏松 (LA)的神经心理功能改变及其特征。方法 :对 2 9例无临床症状体征的LA患者和2 5例一般资料与之匹配的正常人进行多种神经心理测定 ,测验包括视觉保持测验 (VRT)、韦氏成人智力量表(WAIS—RC)和Zung氏抑郁自评量表 (SDS)。结果 :LA组的VRT两个记分系统的成绩和WAIS—RC中的记忆 /注意因子标准分 (MFSs)低于正常组 ,两组总智商 (FIQ)和SDS标准分无显著性差异。结论 :无神经系统临床症状体征的LA可以导致特定的认知功能障碍 ,其特征是一定程度的视—空能力缺陷。
Objective:To investigate the neuro psychological characteristics and their change in leukoaraiosis(LA).M ethods:29 asymotamatic LA sub jects and 25 normal controls were compared on a comprehensive neuropsychological test battery,which included Revised Visual Retention Test(VRT),Wechsler Adult I n telligence Scale-Revised in China(WAIS-RC),and Zung's Self-rated Depression Scal e (SDS).Both groups were matched for sex,age and education.Results:The LA group s cored lower on the VRT than did the control group ,and the mean standard score o f the Memory and/or Freedom From Distractibility factor(MFSs)of the WAIS-RC in t he LA group was lower than that of the control group.There were no significant d ifferences o f the Full Scale IQ of the WAIS-RC and the score of the SDS between the two grou ps. Conclusion:LA may contribute to cogniti ve impairment in the neurologically healthy elderly,especially involving deficits of visuospatial ability ,disfunct ion of memory and attention,as well as slowing of mental processing.
