Is it ADHD, or does your child have sleep apnea? - Philly.com Not much is understood by parents about snoring or sleep apnea, especially in their children. The Stanford School of Medicine states that about 10% of children 10 years of age and younger snore and, of those children who snore, about 20% will have obstructive sleep apnea. Snoring can be a sign that your child has sleep apnea as it indicates, at the very least, that their airway is partially obstructed during sleep. Sleep apnea is a serious medical condition that can interrupt or stop your child’s breathing, prevent a normal night’s sleep, impair growth, and lead to a lower quality of life. It also can cause serious fatigue during the day which is why it is so often confused with ADHD.
