Discussion To our knowledge, this is the first study examining the prevalence of clinically assigned sleep disorders (ICD diagnoses) as well as of sleep medication prescriptions in individuals with and without ADHD in a nationally representative cohort from childhood to older adulthood. In this study based on 6.4 million individuals, of whom 145 490 had an ADHD diagnosis, we found that ADHD was significantly associated with an excess risk of sleep disorders from childhood to older adulthood.
