The present study aims to examine the current status, research hotspots, and trends of epilepsy following subarachnoid hemorrhage (SAH) by generating visual maps, and offering research directions and references in the field of post-SAH epilepsy.
We employed bibliometric methods using VOSviewer, Microsoft Excel, and SRplot to visually analyze data on post-SAH epilepsy from the Web of Science Core Collection (WoSCC). Analysis parameters included the number of papers (NP), countries/regions, institutions, authors, journals, and keywords, assessed through network mapping.
Our analysis included 1,172 publications from 1995 to 2024. The annual NP showed a growing trend, with the United States contributing the highest NP (488) and demonstrating close collaborations with other countries/regions. Harvard University in the United States had the highest institutional output, with 62 papers. The most prolific author was Jan Claassen, with 35 publications, while was the journal with the highest NP (51). The primary disciplinary category was Clinical Neurology. Keywords such as 'inflammation,' 'prevalence,' and 'delayed cerebral ischemia' (DCI) emerged as recent research hotspots.
Over the past three decades, there has been a significant upward trend in the annual NP on post-SAH epilepsy. The United States has maintained a leading position in this field. Current research primarily focuses on the pathogenesis, with particular attention to 'inflammation' and 'DCI'.
本研究旨在通过生成可视化图谱，考察蛛网膜下腔出血（SAH）后癫痫的现状、研究热点及趋势，为SAH后癫痫领域提供研究方向和参考。
我们采用文献计量学方法，使用VOSviewer、Microsoft Excel和SRplot对来自科学网核心合集（WoSCC）的SAH后癫痫数据进行可视化分析。分析参数包括论文数量（NP）、国家/地区、机构、作者、期刊和关键词，通过网络映射进行评估。
我们的分析涵盖了1995年至2024年的1172篇出版物。年度NP呈增长趋势，美国贡献的NP最高（488篇），并与其他国家/地区展示了密切合作。美国哈佛大学的机构产出最高，有62篇论文。发文量最多的作者是扬·克拉森，有35篇出版物，而《 》是NP最高的期刊（51篇）。主要学科类别是临床神经病学。“炎症”“患病率”和“迟发性脑缺血”（DCI）等关键词成为近期研究热点。
在过去三十年中，SAH后癫痫的年度NP呈显著上升趋势。美国在该领域保持领先地位。当前研究主要集中在发病机制上，尤其关注“炎症”和“DCI”。
