Insights
Children with Rett (RTT), Angelman (AS), and Prader-Willi (PWS) syndromes experience frequent sleep disturbances. Sleep-disordered breathing is common in RTT and PWS, highlighting the need for clinical screening.
Area of Science:
- Neuroscience
- Pediatrics
- Genetics
Background:
- Sleep is crucial for neurodevelopment and health.
- Sleep disturbances are more common in children with neurodevelopmental syndromes.
- Rett (RTT), Angelman (AS), and Prader-Willi (PWS) syndromes are genetically determined neurodevelopmental disorders.
Purpose of the Study:
- Characterize sleep behavior in RTT, AS, and PWS.
- Identify effective approaches for treating sleep problems in these populations.
- Compare sleep-related symptoms across syndromes and with typically developing controls.
Main Methods:
- Recruited children from Rare Diseases Clinical Research Network registries.
- Enrolled unaffected siblings as related controls.
- Administered validated sleep questionnaires to parents.
Main Results:
- Analyzed sleep data from 714 participants (ages 2-18).
- Younger children with AS reported more sleep problems than RTT or PWS.
- Older children with RTT had increased daytime sleepiness; RTT showed more sleep-disordered breathing than PWS.
Conclusions:
- Individuals with RTT, AS, and PWS frequently experience sleep problems, including sleep-disordered breathing.
- Clinical assessment and management should include screening for sleep problems in neurogenetic disorders.
- Data can inform treatment strategies and clinical trials for sleep disturbances.
Background:
Adequate sleep is important for proper neurodevelopment and positive health outcomes. Sleep disturbances are more prevalent in children with genetically determined neurodevelopmental syndromes compared with typically developing counterparts. We characterize sleep behavior in Rett (RTT), Angelman (AS), and Prader-Willi (PWS) syndromes to identify effective approaches for treating sleep problems in these populations. We compared sleep-related symptoms across individuals with these different syndromes with each other, and with typically developing controls.
Methods:
Children were recruited from the Rare Diseases Clinical Research Network consortium registries; unaffected siblings were enrolled as related controls. For each participant, a parent completed multiple sleep questionnaires including Pediatric Sleep Questionnaire (Sleep-Disordered Breathing), Children's Sleep Habits Questionnaire (CSHQ), and Pediatric Daytime Sleepiness Scale.
Results:
Sleep data were analyzed from 714 participants, aged two to 18 years. Young children with AS had more reported sleep problems than children with RTT or PWS. Older children with RTT had more reported daytime sleepiness than those with AS or PWS. Finally, all individuals with RTT had more evidence of sleep-disordered breathing when compared with individuals with PWS. Notably, typically developing siblings were also reported to have sleep problems, except for sleep-related breathing disturbances, which were associated with each of the genetic syndromes.
Conclusions:
Individuals with RTT, AS, and PWS frequently experience sleep problems, including sleep-disordered breathing. Screening for sleep problems in individuals with these and other neurogenetic disorders should be included in clinical assessment and managements. These data may also be useful in developing treatment strategies and in clinical trials.
