摘　　要：目的分析卒中后认知障碍管理的研究现状和热点,为卒中后认知障碍管理提供依据。方法系统检索2011年11月1日—2021年11月1日Web of Science数据库中与卒中后认知障碍管理相关的文献,从年份、期刊及国家等方面进行文献计量分析,同时采用狄利克雷分配(LDA)主题模型挖掘潜在主题,并确定主题关键词。结果共纳入1815篇文献,文献数量整体呈稳步增长趋势,来源出版物共计394种,载文量最大的期刊是Stroke(61篇),美国是该领域研究的主要国家,发文量占34.93%(634/1815)。通过LDA主题模型识别6个研究主题,分别为卒中后认知障碍患者各领域功能缺损及心理健康、神经心理筛查及评估工具、康复干预训练及效果评价、家庭照顾者的支持与健康促进、卒中后认知障碍的流行病学特征以及相关危险因素。结论卒中后认知障碍管理的研究总体呈上升趋势,通过对相关研究的主题挖掘与分析,有利于进一步为卒中后认知障碍管理的开展提供发展方向和信息支撑。Objective To analyze the research status and hotspots of post-stroke cognitive impairment management,so as to provide basis for post-stroke cognitive impairment management.Methods The articles on the post-stroke cognitive impairment management in the Web of Science from November 1,2011 to November 1,2021 were retrieved systematically.The bibliometric analysis was carried out from the aspects of year,journal and country.The Latent Dirichlet Allocation(LDA)topic model was used to mine potential topics and determine topic keywords.Results A total of 1815 articles were included.The overall number of the article showed a steady growth trend,with a total of 394 source publications,and the journal with the largest number of articles was Stroke(61 articles).The United States was the main country for research in this field,with 34.93%(634/1815)of the articles issued.Six topics were identified through the LDA topic model,including functional impairment and mental health in various fields of patients with post-stroke cognitive impairment,neuropsychological screening and evaluation tools,rehabilitation training and effect evaluation,support and health promotion of family caregivers,epidemiological characteristics and risk factors of post-stroke cognitive impairment.Conclusions The research on the post-stroke cognitive impairment management is generally on the rise.The topic mining and analysis of the research is conducive to further providing the development direction and information support for the post-stroke cognitive impairment management.
