Overview

Caring for a child with CHARGE syndrome can be challenging, especially when sleep problems and breathing issues are involved. Here, we describe the effective ways to manage sleep disturbances and airway obstruction in CHARGE syndrome that will fill you with confidence. We will explore why these issues happen and what clinical steps can help your child (and your family) sleep more safely and better.

To manage sleep disturbances and airway obstruction in people affected by CHARGE syndrome, healthcare providers focus on treating the physical causes of breathing problems and improving the child’s sleep environment and routine. This typically includes correcting any airway blockages (opening up blocked nasal passages or repairing a cleft palate early in life and removing enlarged tonsils or adenoids if they are causing obstruction).¹ Many children with CHARGE who have obstructive sleep apnea (OSA) benefit from conventional OSA treatments like continuous positive airway pressure (CPAP) therapy, adenotonsillectomy (surgical removal of tonsils/adenoids), and in severe cases, tracheostomy (a breathing tube in the neck).² Doctors will often perform a sleep study to identify issues like OSA and guide these treatments. Additionally, addressing related problems, such as acid reflux (with medication or diet changes) and chronic ear or sinus issues, can improve sleep. Beyond medical treatments, good sleep hygiene is important: a calming bedtime routine, a comfortable sleep environment, and a consistent sleep schedule help the child settle to sleep. If a child’s internal clock is disrupted (common in CHARGE due to vision problems), doctors may recommend melatonin or controlled light exposure to regulate their sleep-wake cycle.¹ By blending medical interventions for breathing with behavioural and environmental strategies for better sleep, many children with CHARGE syndrome can achieve more restful nights and better overall health.

No,w let’s learn why children with CHARGE syndrome often have sleep disturbances and airway obstruction. We will also talk about detailed clinical management strategies that can make a real difference in CHARGE syndrome.

What is charge syndrome?

CHARGE syndrome is a complex genetic condition (occurring in about one in 8’500 births) that affects multiple organ systems.²  “CHARGE” stands for a cluster of features:

• Coloboma (eye defects)
• Heart defects
• Atresia of choanae (blocked nasal passages)
• Retardation of growth/development
• Genital anomalies
• Ear abnormalities (often with hearing loss)

Each child with CHARGE is unique, but many share certain challenges, the main being sleep. More than half of all children with CHARGE syndrome experience significant sleep difficulties.¹ These sleep problems can include trouble falling asleep, frequent night awakenings, and abnormal sleep patterns.

Sleep disturbances in charge syndrome

Several factors contribute to why kids affected by CHARGE syndrome have difficulty sleeping. Many issues are directly related to the syndrome’s physical manifestations and medical complexities.

Airway and breathing problems

Choanal atresia (narrowed or blocked airways) makes it hard to breathe through the nose, especially at night. Some people affected by CHARGE syndrome are born with a cleft palate (an opening in the roof of the mouth). Both choanal atresia and cleft palate could lead to OSA, where breathing stops and starts during sleep. Other structural airway issues are frequent too. For example, a small jaw (micrognathia), floppy airway (laryngomalacia) or narrowed windpipe (subglottic stenosis) can partially block the airway and disrupt breathing at night. Some have a tendency for their airway to collapse (tracheomalacia), which can further complicate breathing. There are quite a few challenges, so it’s no surprise that many kids with CHARGE wake up often, snore or gasp in their sleep.² 

Sensory impairments

Many children with CHARGE have significant visual impairments or are completely blind. Many are also affected by hearing loss due to ear abnormalities. These sensory issues can directly affect sleep. The brain produces melatonin (the sleep hormone) in response to darkness. Melatonin helps in regulating the 24-hour circadian rhythm. But a child with little or no light perception may not produce melatonin in a typical day-night pattern, disrupting their internal clock and sleep cycles.³ Meanwhile, hearing loss can make a child feel isolated or unsafe when lying in a dark, quiet room. Kids might not hear the comforting sounds of their environment or parents, which could lead to anxiety at bedtime. This can make it harder for people affected by hearing loss to relax, soothe and finally, fall asleep.¹

Gastroesophageal reflux and pain

Gastroesophageal reflux and abdominal pain are common in individuals with CHARGE syndrome but are often overlooked. Clinical signs of digestive issues, including reflux and constipation, are often present. However, despite how common these symptoms are, there has been very little research into gastrointestinal problems in CHARGE. Constipation, in particular, can be persistent and significantly impact comfort, behaviour and sleep if not addressed.^1,4

Behavioural and developmental factors

It is difficult to predict how much behavioural problems can affect sleep and how much sleep issues can affect one’s behaviour. It is known that among children with CHARGE syndrome, lack of sleep is associated with poor social skills, anxiety (which may be linked to numerous early hospitalisations), and self-absorbed behaviour. Sleep apnoea could be playing a key role in this cycle, making it harder for children to regulate their emotions or engage socially during the day.¹

Clinical management strategies

Treating structural airway problems

Addressing anatomical blockages is a top priority. In early infancy, if a baby is born with bilateral choanal atresia (both nasal passages blocked), it’s a medical emergency because newborns breathe almost exclusively through their nose.⁵ Surgeons will perform a procedure to open the nasal airway (often drilling through the blockage or placing stents) as soon as possible. In childhood, any persistent nasal obstruction from choanal atresia repair scar tissue can be revised if needed to ensure the child can breathe through their nose.¹

Cleft palate is treated with a surgery called palatoplasty, normally during early childhood. Palatoplasty helps improve breathing, feeding, and speech. Jaw abnormalities, such as a small lower jaw (micrognathia), may be managed with positioning techniques, airway monitoring or surgical interventions. For example, mandibular distraction to help open the airway and reduce breathing difficulties during sleep.^1,6 Adenotonsillectomy is typically performed as a first-line treatment for obstructive sleep apnoea when enlarged tonsils and adenoids are contributing to airway blockage. Tracheostomy is usually considered when less invasive treatments fail or in severe cases with persistent airway obstruction.⁷

Continuous positive airway pressure (CPAP) and supplemental oxygen

You may have heard doctors mention treatments like CPAP or supplemental oxygen. CPAP stands for Continuous Positive Airway Pressure, and it works by gently blowing air through a mask to keep the airways open during sleep. It’s been shown to boost energy levels, improve mood, and reduce feelings of sleepiness and sadness. On the other hand, supplemental oxygen doesn’t use pressure but provides extra oxygen through a small tube under the nose. This can be especially helpful for improving physical comfort and easing pain. Both treatments can also support general well-being. It’s been noted that the more tired someone feels before starting treatment, the more they tend to benefit. So, if someone you know seems extra sleepy or worn out, these therapies might offer noticeable relief.⁸

Managing gastro pain

Treating gastrointestinal issues in CHARGE syndrome often means combining different strategies to help with symptoms like constipation, reflux and abdominal discomfort. Simple lifestyle changes like increasing fluids, encouraging daily exercise and using abdominal massage can make a big difference. Medications such as polyethene glycol (PEG), Senokot or reflux treatments like omeprazole may also be used. Behavioural techniques and speech-language therapy can help children who have struggles with chewing or swallowing. Special diets like low-FODMAP (reducing certain kinds of carbohydrates) or dairy-free plans can support digestion and reduce tummy problems as well.⁴

Melatonin and sleep routine

Melatonin is a naturally occurring hormone that tells the body when it's time to sleep. For children with sleep apnea, it won’t stop breathing pauses, but can improve sleep quality and make it easier to fall asleep. Creating a calming bedtime routine and limiting screen time can support melatonin’s effects. A low dose, usually 1 to 3 mg before bed, may be prescribed. Long-term use should be monitored, as the body can get used to it. When used carefully, melatonin can support better rest and improve how your child feels each day.⁹

FAQs

How can I tell if my child affected by charge syndrome has obstructive sleep apnea (OSA)?

Watch for common signs of OSA: loud snoring most nights, pauses in breathing, gasping or choking sounds and very restless sleep are red flags you should look out for.¹⁰ Children with OSA may also sweat a lot at night or prefer sleeping propped up. During the day, your child might be unusually sleepy or overly active and have trouble focusing (poor sleep can sometimes look like ADHD in kids).¹¹  If you observe these signs, talk to your doctor. They may refer you for a pediatric sleep study to confirm if it’s OSA. Since over half of children with CHARGE have sleep apnea, it’s worth checking.² Diagnosing OSA is the first step to treating it and will greatly help your child’s health and development. 

What should I change at home to improve sleep?

A calming bedtime routine, a consistent schedule, heavy duvets, the right room temperature and a quiet, comfy sleep space can make a big difference. Limit screens before bed, too.¹

Summary

Helping your loved one affected by CHARGE syndrome sleep starts with understanding all the things that can affect their breathing and comfort at night. There are numerous strategies to promote better sleep, ranging from clearing obstructions in the airways and treating reflux to controlling constipation and using devices like CPAP or melatonin. Surgery, like adenotonsillectomy or even tracheostomy, might be needed in some cases, while others get better from gentle routines and dietary changes. Since each person is unique, care strategies must be customised and adjusted. Many families discover that better night's sleep is indeed achievable with the correct assistance.
