Sleep and behavioral problems in Down syndrome: differences between school age and adolescence

Area of Science:

• Neuroscience
• Developmental Psychology
• Sleep Medicine

Background:

• Individuals with Down syndrome (DS) exhibit a high prevalence of sleep problems.
• Existing research highlights links between sleep difficulties and emotional/behavioral issues in DS.
• However, age-specific differences in these associations remain underexplored.

Purpose of the Study:

• To investigate age-related differences in sleep problem distribution among individuals with DS.
• To identify age-specific associations between sleep problems and emotional/behavioral issues in DS.
• To compare sleep problem patterns in school-aged children with DS versus adolescents with DS.

Main Methods:

• Retrospective study design.
• Inclusion of 289 participants with DS, aged 6-18 years.
• Analysis of sleep problems and emotional/behavioral issues across distinct age groups (school age and adolescence).

Main Results:

• Significant differences in sleep problem distribution were observed between age groups.
• Distinct patterns emerged in the associations between emotional/behavioral difficulties and specific sleep problems (e.g., sleep-related breathing, parasomnias) based on age.
• Sleep-wake transition disorders and excessive daytime somnolence showed consistent links with internalizing and externalizing problems across both age groups.

Conclusions:

• Sleep problems and their associations with emotional/behavioral issues in Down syndrome are age-dependent.
• Neuropsychiatric and psychological evaluations for individuals with DS must incorporate age-specific considerations.
• Tailored interventions addressing age-specific sleep and behavioral needs are crucial for individuals with DS.
