What Is Sleep Apnea and How Common Is It in Kids?
Pediatric obstructive sleep apnea (OSA) is a sleep disorder in which a child’s airway becomes partly or completely blocked during sleep, causing repeated pauses in breathing. Those interruptions can fragment sleep and affect how a child functions during the day.
Childhood OSA affects an estimated 1% to 5% of children, with the condition most common between ages 2 and 6. Symptoms can include loud snoring, mouth breathing, restless sleep, gasping or choking, and noticeable pauses in breathing.
The connection with ADHD is particularly important because the conditions can overlap. A 2026 systematic review and meta-analysis found a pooled OSA prevalence of 44% among children with ADHD, based on 11 longitudinal studies involving 903 children.
“Not only does ADHD cause sleep problems, but sleep problems aggravate ADHD symptoms,” psychiatrist J.J. Sandra Kooij told ADDitude. The overlap means sleep apnea can sometimes complicate the picture when a child has difficulty paying attention, controlling impulses or regulating behavior.
What Causes Sleep Apnea in Children?
The most common cause of pediatric OSA is enlarged tonsils and adenoids, which can narrow the airway during sleep. Other potential contributors include facial or skull structure, certain genetic or neuromuscular conditions and obesity, particularly among teenagers.
Researchers also emphasize that diagnosing pediatric sleep apnea can be challenging because symptoms don’t always look the way parents expect. A child doesn’t necessarily appear sleepy during the day and may instead seem hyperactive, inattentive, irritable or have difficulty at school.
A 2024 review notes that symptoms such as hyperactivity and attention difficulties can overlap substantially with ADHD. This creates a risk that sleep-related problems may be overlooked when behavioral symptoms are attributed entirely to ADHD.
That overlap doesn’t mean sleep apnea causes ADHD or that an ADHD diagnosis is incorrect. Instead, the evidence suggests clinicians may need to consider both conditions when children display symptoms associated with either disorder.
What Can Parents Do About Childhood Sleep Apnea?
Parents should pay attention to persistent snoring, pauses in breathing, gasping, restless sleep and unusual daytime behavior. Mayo Clinic recommends speaking with a healthcare professional when children show symptoms of obstructive sleep apnea, particularly frequent snoring.
Diagnosis may involve a medical history, physical examination and, when appropriate, an overnight sleep study. Treatment depends on the cause and severity and can include removing enlarged tonsils or adenoids, medication, lifestyle changes or continuous positive airway pressure (CPAP).
Parents can also reduce some risk factors by helping children exercise regularly, managing allergies and avoiding exposure to tobacco smoke. Cleveland Clinic notes, however, that most causes of childhood sleep apnea cannot be prevented, so parents shouldn’t assume the condition is the result of something they did or failed to do.
The important message for families is that persistent sleep problems deserve medical attention. As Cleveland Clinic puts it, “If you notice signs of childhood sleep apnea, visit a healthcare provider for an evaluation,” particularly when breathing interruptions occur during sleep.
