Exploring sleep problems in young children with cerebral palsy - A population-based study.

Area of Science:

• Pediatric Neurology
• Sleep Medicine
• Child Development

Background:

• Sleep disturbances are common in children with cerebral palsy (CP).
• Understanding the prevalence and characteristics of sleep problems in young children with CP is crucial for targeted interventions.
• Previous research has highlighted sleep issues in CP, but population-specific data in young age groups are needed.

Purpose of the Study:

• To investigate the prevalence and nature of sleep problems in a population-based cohort of children aged 5-10 years with cerebral palsy (CP) in Stockholm, Sweden.
• To explore associations between sleep problems, CP subtypes, functional motor levels, and pain.

Main Methods:

• A cross-sectional study involving 118 children (mean age 7.4 years) with CP.
• Data collection included medical record review and parental telephone interviews using structured questions and the Insomnia Severity Index (ISI).
• Children were categorized by CP subtype and Gross Motor Function Classification System - Expanded and Revised (GMFCS-E&R) levels.

Main Results:

• Sleep problems were reported in 41% of the children.
• Night-time sleep was negatively affected by pain in 80% of children experiencing sleep issues.
• Sleep problems were more prevalent and severe in children with dyskinetic CP and those in GMFCS-E&R level V.
• A strong correlation was found between pain-related sleep problems and the ISI total score (r=0.83, p<0.001).

Conclusions:

• Over 40% of young children with CP experience sleep problems.
• Sleep disturbances are significantly more common and severe in children with dyskinetic CP and higher GMFCS-E&R levels.
• Pain is a major contributing factor to sleep problems in this population, particularly in severely affected children.
