Insights
Children with ADHD and typically developing children show different sleep patterns. Sleep issues in children with ADHD may affect both nighttime and daytime sleep, impacting overall sleep quality.
Area of Science:
- Pediatric Sleep Medicine
- Neurodevelopmental Disorders
- Behavioral Sleep Medicine
Background:
- Daytime sleepiness is a common concern in children.
- Understanding the relationship between habitual sleep and objective sleep measures is crucial for diagnosing sleep disturbances.
Purpose of the Study:
- To investigate the association between habitual sleep patterns, polysomnography (PSG)-measured sleep, and daytime sleepiness in children with Attention-Deficit/Hyperactivity Disorder (ADHD) and typically developing children.
- To explore differences in sleep patterns and their correlation with daytime sleepiness between these two groups.
Main Methods:
- Eighty-two children (7–11 years; 26 ADHD, 56 typically developing) underwent 5 nights of actigraphy for habitual sleep and 1 night of polysomnography (PSG) at home.
- Daytime sleepiness was assessed using the Multiple Sleep Latency Test (MSLT) in a laboratory setting.
- Spearman correlations analyzed relationships between MSLT, Epworth Sleepiness Scale, PSG, and actigraphy sleep measures.
Main Results:
- In typically developing children, longer sleep latency on PSG and actigraphy correlated with longer MSLT sleep latencies.
- In children with ADHD, actigraphy measures of sleep restlessness and time in slow-wave sleep positively related to MSLT sleep latencies.
- A differential relationship between habitual/immediate sleep patterns and daytime sleepiness was observed between the groups.
Conclusions:
- Children with ADHD exhibit distinct sleep patterns compared to typically developing children concerning daytime sleepiness.
- Sleep initiation and maintenance problems may be present in children with ADHD during both nighttime and daytime.
- Further research into tailored sleep interventions for children with ADHD is warranted.
Abstract:
The present study assessed the association between habitual sleep patterns and one night of PSG measured sleep with daytime sleepiness in children with ADHD and typically developing children. Eighty-two children (26 ADHD, 56 typically developing children), between 7 and 11 years, had nighttime sleep recorded using actigraphy over five nights (habitual sleep patterns) and polysomnography during one night (immediate sleep patterns), both within their home environments. Daytime sleepiness was examined using the multiple sleep latency test within a controlled laboratory setting the following day. Using Spearman correlations, the relationships between mean sleep latencies on the multiple sleep latency test and scores on a modified Epworth Sleepiness Scale with polysomnographic measures of sleep quality and architecture and with actigraphic sleep quality measures were examined. Longer sleep latency, measured using polysomnography and actigraphy, was related to longer mean sleep latencies on the multiple sleep latency test in typically developing participants, whereas actigraphic measures of sleep restlessness (time awake and activity during the night), as well as time in slow-wave sleep, were positively related to mean sleep latency on the multiple sleep latency test in children with ADHD. These results show a differential relationship for children with ADHD and typically developing children between habitual and immediate sleep patterns with daytime sleepiness and suggest that problems initiating and maintaining sleep may be present both in nighttime and daytime sleep.
