Understanding Sleep Disorders in ASD Kids: Insights from Our Journey with Sleep Apnea and Hypoventilation

Sleep challenges affect many children with autism spectrum disorder (ASD). Research shows that 50% to 80% of children with ASD experience some form of sleep disorder, ranging from difficulty falling asleep to breathing problems during sleep. Last week, my oldest son, who has ASD, underwent an overnight sleep study in La Crosse. The experience and results opened my eyes to how sleep disorders can impact children with autism and what steps families can take to improve their child’s sleep and overall well-being.

What We Learned from the Sleep Study

The night of the sleep study was surprising. Despite having multiple wires attached to his face and body to monitor breathing, oxygen levels, and brain activity, my son slept better than I expected. The next day, the results appeared on our MyChart app, but the medical terms were confusing. Soon after, the provider called to explain the diagnosis: mild pediatric sleep apnea with hypoventilation present.

What is Hypoventilation?

Hypoventilation means that during sleep, the child is not breathing deeply or frequently enough to get rid of enough carbon dioxide from the body. This can cause carbon dioxide levels to rise and oxygen levels to drop, leading to poor oxygen supply to the brain and other organs. When combined with sleep apnea—which causes repeated pauses in breathing—hypoventilation can seriously disrupt sleep quality.

How Sleep Apnea and Hypoventilation Affect Autism Symptoms

Sleep apnea and hypoventilation can worsen autism symptoms in several ways:

• Increased irritability and mood swings: Poor oxygen supply and fragmented sleep can make children more prone to emotional outbursts.

• Difficulty with attention and learning: Sleep disruptions affect brain function, making it harder for children to focus and process information.

• Heightened repetitive behaviors: Lack of restful sleep can increase anxiety and repetitive actions common in ASD.

• Reduced ability to regulate sensory input: Sleep problems can make sensory sensitivities worse, leading to more distress.

  
  

Research supports these observations. A study published in the Journal of Autism and Developmental Disorders found that children with ASD and untreated sleep apnea showed more severe behavioral challenges than those without sleep apnea.

Our Next Step: Surgery to Improve Breathing

To help open my son’s airway and improve his sleep, he will have his tonsils and adenoids removed. Enlarged tonsils and adenoids often block the airway in children with sleep apnea. This surgery is common and has helped many children breathe better at night.

We are hopeful this procedure will:

• Improve his oxygen levels during sleep

• Reduce apnea episodes and hypoventilation

• Lead to better sleep quality

• Decrease unwanted behaviors and improve daytime functioning

  
  

Signs to Watch for That May Mean Your Child Needs a Sleep Study

If your child has ASD, it’s important to discuss sleep concerns with your primary care provider. Some signs that may indicate a sleep disorder include:

• Falling asleep during the day after they have stopped taking naps

• Loud or frequent snoring

• Mouth breathing during sleep or waking up

• Frequent nighttime awakenings

• Restless sleep or unusual movements during the night

• Daytime irritability or hyperactivity

  
  

If you notice these signs, ask your provider about the possibility of a sleep study. Early diagnosis and treatment can improve your child’s quality of life.

Why Sleep Matters for Children with ASD

Sleep is essential for brain development, learning, and emotional regulation. Children with ASD already face challenges in these areas, so poor sleep can make symptoms harder to manage. Addressing sleep disorders can lead to:

• Better mood and behavior

• Improved attention and learning

• Reduced sensory sensitivities

• Overall improved quality of life for the child and family

  
  

Sleep disorders in children with autism are common but often overlooked. Our experience with sleep apnea and hypoventilation showed us how important it is to pay attention to sleep health. If your child shows signs of sleep problems, don’t hesitate to seek professional advice. Proper diagnosis and treatment can make a significant difference in your child’s well-being and daily functioning.
