Key takeaway: between 23% and 46% of children with cerebral palsy (CP) experience clinically significant sleep disorders — a far higher rate than in typically developing peers. Sleep-disordered breathing (SDB) — which encompasses obstructive sleep apnea (OSA), central sleep apnea (CSA), and hypoventilation — arises from intrinsic and extrinsic factors: muscle tone abnormalities, pain and spasticity, gastroesophageal reflux, sialorrhea, seizure disorders, and the use of muscle relaxants or anticonvulsants. Polysomnography remains the diagnostic gold standard. Early identification and treatment prevent long-term cardiovascular and neurobehavioral complications and improve quality of life for both child and family.
This summary is based on the review by Dhandayuthapani and colleagues published in Paediatric Respiratory Reviews in 2026 (vol. 58, pp. 32-38).

Why sleep disorders in CP remain underdiagnosed
Cerebral palsy (CP) is the most common cause of chronic physical disability in childhood. Although primarily defined as a movement and posture disorder, CP is frequently associated with numerous comorbidities. Among these, sleep disturbances and sleep-disordered breathing (SDB) emerge as crucial yet often unrecognized issues.
The review analyzes the prevalence, complex multifactorial pathophysiology, diagnostic methods, and therapeutic management strategies of these conditions in children with cerebral palsy.
How common are sleep disorders in cerebral palsy
Scientific literature indicates that between 23% and 46% of children with CP exhibit clinically significant sleep disorders, a frequency substantially higher than that observed in the healthy pediatric population.
These disorders not only compromise neurocognitive development, behavior, and the child’s quality of life — already severely challenged by the primary pathology — but also generate a heavy emotional and physical burden (caregiver burden) for the entire family unit, exacerbating stress and fragmenting parental sleep.
Pathophysiology: why sleep is compromised in CP
Sleep disturbances in CP do not stem from a single cause; rather, they result from a synergistic interaction of intrinsic and extrinsic factors:
- Motor and postural difficulties: the inability to independently change positions in bed causes prolonged discomfort and frequent awakenings.
- Pain and spasticity: nocturnal muscle cramps, dystonias, and secondary musculoskeletal pain are the primary predictors of poor sleep quality.
- Gastrointestinal issues: gastroesophageal reflux disease (GERD) and chronic constipation cause micro-arousals and pain during the night.
- Circadian rhythm alterations: in children with severe visual or neurological deficits, melatonin production is often deregulated, making it difficult to fall asleep.
Why children with CP are predisposed to obstructive sleep apnea
Sleep-disordered breathing encompasses three distinct pathologies: obstructive sleep apnea (OSA), central sleep apnea (CSA), and hypoventilation. Children with CP are particularly predisposed to OSA due to:
- hypotonia or abnormal coordination of pharyngeal muscles, which collapse during inspiration;
- sialorrhea (excessive salivation) and swallowing difficulties, which increase the risk of upper airway obstruction and micro-aspiration;
- use of muscle relaxants or anticonvulsant medications, which can further depress central respiratory drive or airway patency.
How sleep disorders are diagnosed in children with cerebral palsy
The primary diagnostic tools include:
- History and questionnaires: standardized tools such as the Sleep Disturbance Scale for Children (SDSC) or sleep diaries completed by parents, to detect early warning signs (snoring, respiratory pauses, excessive daytime irritability).
- Polysomnography (PSG): remains the objective gold standard for quantifying the apnea-hypopnea index (AHI) and evaluating sleep architecture, although execution can be complex in children with severe motor disabilities.

How sleep disorders and apnea are treated in CP
Management must necessarily be personalized and multidisciplinary:
- Behavioral and postural interventions: optimization of sleep hygiene (regular routines, reduced screen time) and the use of nocturnal positioning systems (side supports, molded pillows) prescribed by physical therapists to reduce pain and pressure sores.
- Pharmacological therapy: use of melatonin to promote sleep induction, and optimization of therapy for spasticity and reflux.
- Respiratory support: in cases of moderate-to-severe OSA, non-invasive positive airway pressure ventilation (CPAP/BiPAP) or, in rare complex cases, tracheostomy, has been shown to significantly improve respiratory parameters and overall quality of life.
Conclusions and future perspectives
Early identification of sleep disorders and apnea in children with cerebral palsy is a cornerstone for preventing long-term cardiovascular and neurobehavioral complications. Further randomized clinical trials are needed to establish standardized therapeutic guidelines, aimed at relieving young patients and their families from one of the most debilitating comorbidities of cerebral palsy.

Frequently asked questions
How common are sleep disorders in children with cerebral palsy?
Between 23% and 46% of children with cerebral palsy experience clinically significant sleep disorders, a markedly higher rate than in the healthy pediatric population.
Why do children with cerebral palsy have sleep apnea?
Children with CP are predisposed to obstructive sleep apnea because of hypotonia or abnormal coordination of the pharyngeal muscles, which collapse during inspiration; sialorrhea and swallowing difficulties, which increase the risk of upper airway obstruction; and the use of muscle relaxants or anticonvulsants, which can depress central respiratory drive.
What tests diagnose sleep apnea in a child with cerebral palsy?
Polysomnography is the objective gold standard: it quantifies the apnea-hypopnea index (AHI) and evaluates sleep architecture, although execution can be complex in children with severe motor disabilities. Initial assessment uses history-taking and standardized questionnaires such as the Sleep Disturbance Scale for Children (SDSC) or parent-completed sleep diaries.
Is melatonin helpful for children with cerebral palsy who cannot sleep?
Melatonin is used to promote sleep induction, within a personalized, multidisciplinary approach that also includes optimizing therapy for spasticity and gastroesophageal reflux. In children with severe visual or neurological deficits, endogenous melatonin production is often deregulated.
When is CPAP needed for a child with cerebral palsy?
In cases of moderate-to-severe obstructive sleep apnea, non-invasive positive airway pressure ventilation (CPAP/BiPAP) has been shown to significantly improve respiratory parameters and overall quality of life. In rare complex cases, tracheostomy may be required.
Do sleep disorders in cerebral palsy affect the family?
Yes. Beyond compromising the child’s neurocognitive development, behavior, and quality of life, these disorders generate a heavy emotional and physical burden (caregiver burden) for the entire family unit, exacerbating stress and fragmenting parental sleep.
