Attention deficit hyperactivity disorder and dyslexia are common neurodevelopmental disorders in children, with a comorbidity rate reaches as high as 25%-48%. Clinically characterised by inattention, hyperactivity-impulsivity, and impaired reading fluency, accuracy, and spelling, these conditions significantly impact children’s cognitive function, psychological state, and social behavioural development, increasing burdens on families and society. Nevertheless, research into their aetiology and treatment remains exploratory. This paper aims to review potential underlying mechanisms and therapeutic approaches for the co-occurrence of attention deficit hyperactivity disorder and dyslexia, providing guidance for clinical identification, diagnosis, treatment, and prevention of attention deficit hyperactivity disorder with dyslexia.
