The role of mitochondrial dysfunction in diabetes-associated cognitive dysfunction: A bibliometric analysis

BackgroundDiabetes, a prevalent chronic disorder, is frequently complicated by diabetes-associated cognitive dysfunction (DACD). The impact of diabetes on specific cerebral regions accelerates the progression from mild cognitive impairment to Alzheimer's disease. Research has indicated that mitochondrial dysfunction is a pivotal factor in DACD, yet its underlying mechanisms remain elusive.ObjectiveOur research aims to elucidate the research trends in this field over the past fifteen years by employing bibliometric analysis.MethodsA systematic search and aggregation of literatures related to mitochondrial dysfunction in DACD published within the Web of Science Core Collection from 2010 to 2024 were performed. Subsequently, a bibliometric analysis was conducted employing four bibliometric software: HistCite, R-bibliometrix, VOSviewer, and CiteSpace.ResultsA total of 309 papers were identified for analysis. The most prolific country, institution, and authors were China, University of Coimbra, Moreira PI, and Li YS, respectively. The USA, Texas Tech University, and Reddy PH were the key country, institution, and author, respectively. Among references to articles in this field, Diabetes has the most cumulative citations. According to the analysis of co-citations, oxidative stress was the largest cluster. The primary keywords were "Alzheimer's disease" and "oxidative stress". In recent years, the keyword "mitophagy" has received a lot of attention.ConclusionsOxidative stress represents a principal research topic within this field. Mitophagy offers a potential therapeutic avenue for DACD and may emerge as a novel focus of future investigations.
