Background: Rapid eye movement sleep behavior disorder (RBD) represents a parasomnia marked by impaired muscle inhibition during REM sleep, commonly manifesting as vivid dream enactment with potentially violent movements. Its strong association with neurodegenerative diseases, particularly α-synucleinopathies such as Parkinson’s disease, has drawn increasing attention. This study presents a bibliometric overview of global RBD research from 2010 to 2025. Methods: We analyzed 4,204 publications from the Web of Science Core Collection and Scopus databases. Tools including CiteSpace, VOSviewer, Python, R (bibliometrix), Excel, and Charticulator were used to examine publication trends, geographic and institutional distribution, author influence, journal preferences, co-citation networks, and keyword evolution. Results: RBD-related publications increased steadily, with a marked rise after 2015. The United States, China, and Canada were leading contributors, and institutions such as the University of Toronto, Mayo Clinic, and Peking University showed strong productivity and collaboration. Key researchers included Schenck CH, Boeve BF, and Postuma RB. Top journals were Sleep, Neurology, and Movement Disorders. Research has shifted from clinical characterization to biomarker identification and early intervention. Recent themes include α-synuclein pathology, prodromal Parkinson’s disease, and melatonin therapy. Conclusion: RBD research has progressed toward translational approaches focused on early detection and neurodegenerative risk prediction, supported by global collaboration and growing interest in mechanistic insights.
