Summary

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by persistent inattention, hyperactivity, and impulsivity. In adolescents and young people, ADHD is commonly accompanied by insomnia and circadian delay. These co-occurring sleep and circadian disturbances may negatively affect daytime functioning and overall clinical outcomes. Although cognitive behavioural therapy for insomnia (CBT-I) is considered the first-line treatment for insomnia, and bright light therapy may help address circadian issues, their efficacy in adolescents with ADHD and comorbid insomnia and eveningness remains unexplored. This study aims to evaluate whether CBT-I, with or without bright light therapy, improves insomnia, sleep, and circadian as well as other clinical outcomes, and cognitive functioning in youths with ADHD and whether these interventions can also lead to improvements in mood and other clinical symptoms, as well as cognitive functioning.
