Premenstrual syndrome (PMS) and premenstrual dysphoric disorders (PMDDs) both represent the most studied premenstrual disorders. Most studies have substantial prevalence of both PMS and PMDD, though the current understanding of the disorders reflects that PMDD is the more severe disorder of the two. However, there is substantial overlap in the etiopathogenesis and treatment approach of both these disorders.
The current study thus explored trends of the use of PMS and PMDD as diagnostic entities.
The study was conducted using Harzing's Publish or Perish for identifying top 50 cited articles on PMS and PMDD, published between 2013 and 2023. The search and the citation metrics were obtained from Google Scholar through the mentioned software. The citation metrics of the two groups of studies were compared, and appropriate statistical maneuvers were used.
The PMS studies had a higher mean number of citations than PMDD studies. The PMDD studies tended to have a higher number of authors from Psychiatry or related background. The PMDD studies also had higher representation of institutions from the United States of America.
Using citation analysis to study the utilization trends of diagnostic label is a novel approach. This study shows that there is a need for a unique diagnostic entity to represent the premenstrual disorders, and the coexistence of PMS and PMDD is redundant.
经前综合征（PMS）和经前烦躁障碍（PMDD）都是研究最多的经前疾病。大多数研究表明PMS和PMDD的患病率都很高，尽管目前对这些疾病的认识表明PMDD是两者中更严重的疾病。然而，这两种疾病在病因发病机制和治疗方法上有很大重叠。
因此，本研究探讨了PMS和PMDD作为诊断实体的使用趋势。
本研究使用哈津的“发表或灭亡”软件来识别2013年至2023年间发表的关于PMS和PMDD的被引用次数最多的前50篇文章。搜索和引用指标通过上述软件从谷歌学术获取。比较了两组研究的引用指标，并采用了适当的统计方法。
PMS研究的平均被引用次数高于PMDD研究。PMDD研究的作者往往更多来自精神病学或相关背景。PMDD研究中来自美利坚合众国的机构也有更高的代表性。
使用引文分析来研究诊断标签的使用趋势是一种新颖的方法。本研究表明，需要一个独特的诊断实体来代表经前疾病，PMS和PMDD的共存是多余的。
