Developmental dyslexia，a common neurodevelopmental disorder in childhood，is primarily marked by reading proficiency deficits. A wealth of studies have demonstrated that this disorder not only has a detrimental impact on children’s academic achievements but also induces a spectrum of cognitive impairments，self-concept disturbances，and emotional disorders，such as anxiety and depression. Given its high prevalence and severe consequences，the academic community’s interest in childhood dyslexia has been on the rise. This article，through an extensive review of domestic and international research，analyzes the advances in the study of developmental dyslexia from multiple aspects，including its pathogenesis，comorbidity patterns，assessment and screening approaches，and intervention strategies. The overarching goal is to enhance the abilities of clinical practitioners in evaluating and identifying children with developmental dyslexia，so as to lay a solid groundwork for “mechanism elucidation-early identification-targeted intervention”.
