Objective To conduct a scoping review on the influencing factors of comorbid sleep disorders in adolescents with epilepsy, so as to provide a reference basis for clinical prevention and early intervention. MethodsFollowing the methodological framework of scoping review, relevant studies were systematically searched in PubMed, Web of Science, Cochrane Library, Embase, Chinese Biomedical Literature Database, CNKI, Wanfang, and VIP Database. The retrieval time limit was from the establishment of each database to April 30, 2025. The included literatures were summarized and analyzed. ResultsA total of 17 literatures were included, and 17 influencing factors related to comorbid sleep disorders in adolescents with epilepsy were identified, which were mainly divided into six categories: demographic factors, characteristics and severity of epilepsy, treatment-related factors, psychiatric comorbidities, organic neurological damage and neurocognitive development and psychosocial and environmental factors. ConclusionSleep disorders are relatively common in adolescents with epilepsy, and their influencing factors are multifaceted.There is a lack of large-sample research on this population in our country, especially the lack of discussion of the causal relationship between influencing factors and sleep disorders, resulting in a lack of basis for early intervention. Future research urgently needs to systematically identify key influencing factors and explore their internal mechanisms through large-sample surveys, so as to lay a solid scientific foundation for the construction of evidence-based intervention programs.
