Research productivity in catamenial epilepsy: A bibliometric analysis of worldwide scientific literature (1956–2022)

Abstract

Objectives: To perform a bibliometric analysis as a comprehensive review of publications associated with catamenial epilepsy and discuss the current state of knowledge in the field. Methods: Publications published between 1956 and 2022 were retrieved from the Scopus database. Bibliometric analysis was performed using the R package and VOSviewer to show the data and network of journals, organizations, authors, countries, and keywords. The analysis conducted on October 15, 2022, yielded a total of 320 refinement studies. Results: The number of publications has escalated significantly, particularly in the last 20 years. Catamenial epilepsy-related publications originated mostly from medicine and other subject areas, with the United States having the largest publication output. Collaboration is low at the author, organizational, and national levels, especially in the Asian continent. Publications remain scarce, particularly on practice guidelines, risk assessment, and medication-related research. Based on a keyword analysis, a bibliometric analysis identified possible themes for future investigation. Conclusion: Catamenial epilepsy-related literature is crucial but still insufficient, and further studies are required.
