Insights
Children with Williams syndrome (WS) experience significant sleep problems, with 97% of parents reporting issues like bedtime resistance and daytime sleepiness. Early diagnosis and treatment of these sleep difficulties are crucial for improving daytime functioning in children with WS.
Area of Science:
- Neuroscience
- Pediatrics
- Sleep Medicine
Background:
- Sleep is essential for cognitive function, learning, and overall health.
- Sleep disturbances can exacerbate learning and behavioral challenges in children with developmental disorders.
- Williams syndrome (WS) is a genetic neurodevelopmental disorder with an estimated prevalence of 1 in 20,000 live births.
Purpose of the Study:
- To determine the prevalence and specific patterns of sleep problems in school-aged children with Williams syndrome.
- To investigate if sleep difficulties are a core feature of Williams syndrome.
Main Methods:
- A survey study involving parents of 64 children aged 6-12 years with Williams syndrome.
- Comparison with a control group of 92 age-matched healthy children.
- Utilized the Child Sleep Habits Questionnaire and collected general health/background information.
Main Results:
- A very high prevalence of sleep problems was reported, with 97% of parents of children with WS indicating their child experienced sleep difficulties.
- Common issues included significant bedtime resistance, sleep anxiety, night waking, and daytime sleepiness.
- This study represents the first large-scale survey of sleep problems in school-aged children with WS.
Conclusions:
- Sleep problems are highly prevalent and a significant characteristic in school-aged children with Williams syndrome.
- Addressing sleep disturbances early can potentially mitigate learning and behavioral issues.
- Further research should consider sleep disturbances when diagnosing behavioral disorders in children with learning difficulties.
Abstract:
Sleep is critical to optimal daytime functioning, learning and general health. In children with established developmental disorders sleep difficulties may compound existing learning difficulties. The purpose of the present study was to evaluate the prevalence and syndrome specificity of sleep problems in Williams syndrome (WS), a neurodevelopmental disorder affecting around 1 in 20,000 live births. Parents of 64 children with WS, aged 6-12 years, and 92 age matched healthy controls were surveyed about their child's sleep habits. The Child Sleep Habits Questionnaire, general health and background information were collected from the parents. Ninety seven percent of parents reported that their children had sleep problems and reported a high prevalence of sleep difficulties: greater bedtime resistance, sleep anxiety, night waking and daytime sleepiness. This is the first study to our knowledge to survey sleep problems in a large cohort of school age children with WS. Sleep problems in children with learning difficulties are often amendable to treatment if diagnosed early. Furthermore the negative impact of sleep disturbances on daytime behaviour and learning should be measured before diagnoses of behaviourally defined disorders are considered.
