Background: In recent years, more and more evidence has shown that sleep disorders often occur in children with neurodevelopmental disorders, especially in children with autism spectrum disorders. Therefore, the purpose of that study was to summarize the research content in the field of comorbid sleep disorders in autism spectrum disorders and to explore the global research status and frontier trends in that field. Methods: This study collected and identified all publications on comorbid sleep disorders in autism spectrum disorders from January 2000 to May 21, 2024. CiteSpace v.6.1. R6, VOSviewer v.1.1.1.6.15.0, R software, and Microsoft 365 ( office ) were used to conduct bibliometric analysis from the aspects of countries/regions, institutions, authors / cocited authors, journals / co-cited journals, co-cited references and keywords, and to construct a knowledge map. Results: A total of 3006 articles were included in the Web of Science core collection database. The results showed that this field's annual number of publications was generally rising. The USA (1394, 0.16) had the highest publications and centrality. Vanderbilt University (115, 0.06) ranked first in the world in terms of the number of publications and the total link strength. The author Malow, Beth A (59,0.04), has made significant contributions to this field and had a high reference value. The Journal of Autism and Developmental Disorders had the most publications. The 'Diagnostic and Statistical Manual of Mental Disorders: DSM-V (2013)' topped the chart as the most cited reference, while 'mental health' and 'de novo mutation' were pinpointed as the leading hotspots and frontier trends in the research of autism spectrum disorders and sleep disorders.Through the bibliometric analysis of authors, journals, countries/regions, and keywords, this study found that the etiology of autism spectrum disorder comorbid sleep disorders, and drug and nondrug treatment methods was future research hotspots and trends. In the future, it is necessary to further explore the pathogenesis of autism spectrum disorder combined with sleep disorder to promote the development of related drug or non-drug intervention methods.
