目的:探讨慢性失眠对患者认知功能的影响。方法:对慢性失眠患者285例,用事件相关电位(P300)和认知功能筛查量表(CASI)、数字划销测验(NCT)和威斯康星卡片分类试验(WCST)进行评定。结果:慢性失眠患者CASI评分有6项较差,WCST的错误总数、持续错误数、随机错误数高于对照组;NCT的各项得分均有显著差异;P300潜伏期延长,波幅下降。结论:慢性失眠患者存在认知障碍。
Objective： To explore the influence on cognitive function in patients with chronic insomnia. Method： Event related potential （P300）, cognitive abilities screening instrument （CASI）, number cancellation test （NCT） and Wisconsin card sort test （WCST） were evaluated. Results： Compared with patients of control group, the scores of six items of CASI were lower in chronic insomnia group, with total errors and total numbers of persistent error and random error in WCST,and scores of all the items of NCT lower, as well as having a prolonged latency and decreased amplitude of P300, significantly.
