Abstract：
Behavioral and psychological symptoms of dementia (BPSD) have been extensively studied in dementia than its prodromal stage, known as mild cognitive impairment (MCI). A scientometric study on BPSD in MCI would be valuable in synthesizing the existing body of research and providing insights into the trends, networks, and influencers within this area. We searched for related literature in the Web of Science database and extracted complete text and citation records of each publication. The primary objective was to map the research evolution of BPSD in MCI and highlight dominant research themes. The secondary objective was to identify research network characteristics (authors, journals, countries, and institutions) and abundances. A total of 12,369 studies published between 1980 and 2022 were included in the analysis. We found 51 distinct clusters from the co-cited reference network that were highly credible with significant modularity (Q = 0.856) and silhouette scores (S = 0.932). Five major research domains were identified: symptoms, diagnosis, brain substrates, biochemical pathways, and interventions. In recent years, the research focus in this area has been on gut microbiota, e-health, COVID-19, cognition, and delirium. Collectively, findings from this scientometric analysis can help clarify the scope and direction of future research and clinical practices.
摘要：
痴呆的行为和心理症状（BPSD）在痴呆中被广泛研究，而不是其前驱阶段，称为轻度认知障碍（MCI）。MCI中BPSD的科学计量学研究对于综合现有的研究体系和提供对趋势的见解将是有价值的，网络,和这个地区的影响者。我们在WebofScience数据库中搜索了相关文献，并提取了每个出版物的完整文本和引文记录。主要目标是绘制MCI中BPSD的研究演变图，并突出主要研究主题。次要目标是确定研究网络特征(作者，期刊,国家,和机构)和丰富。在1980年至2022年间发表的总共12,369项研究被纳入分析。我们从共同引用的参考网络中发现了51个不同的簇，它们具有高度的可靠性，具有显着的模块化（Q=0.856）和轮廓得分（S=0.932）。确定了五个主要研究领域：症状，诊断,大脑基质，生化途径，和干预。近年来,该领域的研究重点一直是肠道菌群，e-health,COVID-19，认知，和谵妄.总的来说，这项科学计量学分析的结果可以帮助澄清未来研究和临床实践的范围和方向。
