失眠症的诊断除主观抱怨的睡眠不足，还包括日间功能损害。认知损害是失眠症患者常常抱怨的日间功能损害之一，但客观认知测试并没有发现一致的结论。执行功能是高级的认知功能，主要包括三个核心方面：抑制控制、工作记忆和认知灵活性，并对高水平能力的复杂技能控制起着重要作用，执行功能与日常活动、工作和学业成就相关。执行功能对睡眠不足敏感，但目前失眠症与执行功能关系的研究尚未引起足够重视，失眠症患者是否有执行功能损害尚不明确。现就失眠对执行功能的影响进行综述，并探讨失眠症患者执行功能损害的潜在机制以及高觉醒对执行功能的影响，为临床实践和科学研究提供参考。“,”The diagnosis of insomnia includes not only complaints of dissatisfaction with sleep quantity or quality, but also accomplished with daytime dysfunction.Cognitive impairment is one of the daytime dysfunction that insomnia patients often complain about, but the objective measures of cognitive function have no obtained consistent results.Executive functions consist of three core areas, including inhibitory control, working memory and cognitive flexibility.Executive functions represent advanced cognitive processes and are related to daily activities and academic achievement.Executive functions are sensitive to insufficient sleep.However, the relationship between insomnia and executive functions has not attracted enough attention, and it is unclear whether insomnia is related to impairment of executive functions.This article reviews the influence of insomnia on executive functions.The potential mechanism and the role of hyperarousal on executive functions impairment in patients with insomnia is also discussed.
