Bibliometric analysis of publication trends and topics of influenza‐related encephalopathy from 2000 to 2022

Abstract

AbstractBackgroundInfluenza‐related encephalopathy is a rapidly progressive encephalopathy that usually presents during the early phase of influenza infection and primarily manifests as central nervous system dysfunction. This study aimed to analyze the current research status and hotspots of influenza‐related encephalopathy since 2000 through bibliometrics analysis.MethodsThe Web of Science Core Collection (WOSCC) was used to extract global papers on influenza‐related encephalopathy from 2000 to 2022. Meanwhile, the VOSviewer and CiteSpace software were used for data processing and result visualization.ResultsA total of 561 published articles were included in the study. Japan was the country that published the most articles, with 205 articles, followed by the United States and China. Okayama University and Tokyo Medical University published the most articles, followed by Nagoya University, Tokyo University, and Juntendo University. Based on the analysis of keywords, four clusters with different research directions were identified: “Prevalence of H1N1 virus and the occurrence of neurological complications in different age groups,” “mechanism of brain and central nervous system response after influenza virus infection,” “various acute encephalopathy” and “diagnostic indicators of influenza‐related encephalopathy.”ConclusionsThe research progress, hotspots, and frontiers on influenza‐related encephalopathy after 2000 were described through the visualization of bibliometrics. The findings will lay the groundwork for future studies and provide a reference for influenza‐related encephalopathy. Research on influenza‐related encephalopathy is basically at a stable stage, and the number of research results is related to outbreaks of the influenza virus.
