Global Research Trends in Drug-Induced Movement Disorders: A Bibliometric Analysis

Background: Drug-induced movement disorders (DIMDs) represent a significant clinical challenge, encompassing conditions such as tardive dyskinesia, drug-induced parkinsonism, dystonia, and akathisia. While research on DIMDs has expanded, a comprehensive bibliometric analysis of global trends, influential publications, and emerging research themes remains lacking. Objective: This study aims to provide a bibliometric analysis of DIMD research, evaluating publication trends, citation networks, key contributors, and thematic evolution in the field. Methods: A systematic search of bibliographic databases was conducted to identify relevant literature on DIMDs. Bibliometric indicators, including publication output, citation analysis, author collaborations, and keyword co-occurrence, were analyzed. VOSviewer and CiteSpace were used for network visualization and trend mapping. A narrative synthesis of key findings contextualized bibliometric patterns with historical and contemporary research developments. Results: The analysis revealed a steady increase in DIMD publications, with antipsychotic-induced disorders dominating the literature. The United States and Europe emerged as leading contributors, with significant collaborations across institutions. Highly cited papers predominantly focused on pathophysiology, risk factors, and management strategies. Emerging research trends highlighted the role of genetic predisposition, novel therapeutic interventions, and artificial intelligence in early detection. Conclusion: Bibliometric analysis provides valuable insights into the evolution and current state of DIMD research. Future studies should focus on precision medicine approaches, neurobiological mechanisms, and global disparities in management. This review underscores the need for interdisciplinary collaboration to enhance understanding and therapeutic strategies for DIMDs.
