Although ADHD and sleep apnea may not be commonly thought of as similar conditions, they can be mistaken for each other. Dr. Indra Narang, the director of sleep medicine at the Hospital for Sick Children in Toronto, says sleep apnea can cause children to appear distracted and excitable.

A 2012 study by Finnish researchers found that approximately 10 per cent of European children between the ages of six and eight have sleep apnea.
