Prevalence of insomnia in the general population ranges between 31 and 56%, whilst insomnia affects 43 to 80% of adults with Attention Deficit Hyperactivity Disorder (ADHD). Both conditions produce complications to the person’s mental and physical health. Therefore people with ADHD must be assessed for insomnia and both conditions must be treated.
