Children diagnosed with anxiety and ADHD were found to have more sleep problems reported by their parents. There was a significant association between daytime sleepiness and increased teacher reported internalizing symptoms (anxious, withdrawn, depressed, somatic complaints) in children diagnosed with anxiety who were not diagnosed with ADHD. Daytime sleepiness is seen as creating more internalizing symptoms for those children diagnosed with anxiety. Poor sleep was not seen as an exacerbating symptom of ADHD, however it was seen as resulting in poor attentiveness for all groups of children (anxiety, ADHD and ADHD plus anxiety).
