Excessive daytime sleepiness (EDS) is a prevalent symptom among stroke survivors. This symptom is an independent risk factor for stroke and may reduce stroke survivors' quality of life, cognitive functioning, and daytime functional performance. The lack of a universally accepted definition of EDS makes it difficult to measure EDS and synthesize research. The purpose of this integrative review is to describe poststroke EDS, ascertain conceptual and operational definitions of EDS, identify factors that contribute to EDS in stroke survivors, and explore outcomes associated with EDS in stroke survivors. We searched the following databases: PubMed and MEDLINE (OvidSP 1946-April; Week 2, 2015), Embase (OvidSP 1974-March; Week 1, 2015), and PsycINFO (OvidSP 1967-April; Week 2, 2015). Our search yielded 340 articles, 27 of which met inclusion criteria. The literature reveals EDS to be a multidimensional construct that is operationalized with both subjective and objective measures. Choosing measures that can quantify both the objective and subjective components is useful for gaining a comprehensive understanding of EDS. The antecedents of EDS are stroke, sleep-disordered breathing, reversed Robin Hood syndrome, and depression. The outcomes associated with EDS in stroke patients are serious and negative. Via synthesis of this research, we propose a possible framework for poststroke EDS, which may be of use in clinical practice and in research to identify valid quantifying methods for EDS as well as to prevent harmful outcomes in stroke survivors.
日间过度嗜睡（EDS）是中风幸存者中普遍存在的症状。这种症状是中风的独立危险因素，可能会降低中风幸存者的生活质量、认知功能和日间功能表现。由于缺乏对EDS的普遍接受的定义，使得测量EDS和综合研究变得困难。本整合性综述的目的是描述中风后的EDS，确定EDS的概念和操作定义，识别导致中风幸存者出现EDS的因素，并探索与中风幸存者的EDS相关的后果。我们检索了以下数据库：PubMed和MEDLINE（OvidSP 1946年 - 2015年4月第2周）、Embase（OvidSP 1974年 - 2015年3月第1周）以及PsycINFO（OvidSP 1967年 - 2015年4月第2周）。我们的检索共得到340篇文章，其中27篇符合纳入标准。文献表明EDS是一个多维概念，通过主观和客观测量来进行操作化。选择能够量化客观和主观成分的测量方法，有助于全面了解EDS。EDS的前驱因素包括中风、睡眠呼吸障碍、反罗宾汉综合征和抑郁症。中风患者中与EDS相关的后果是严重且负面的。通过对这项研究的综合分析，我们提出了一个可能的中风后EDS框架，这可能有助于临床实践和研究中识别有效的EDS量化方法，并预防中风幸存者出现有害后果。
