Insights

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) show varied sleep issues, with sleep fragmentation potentially worse in the hyperactive/impulsive subtype. Sleep patterns in children with ADHD change with age.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders

Background:

  • Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder in children.
  • Sleep disturbances are frequently reported in children with ADHD, but objective data across different ADHD presentations are limited.

Purpose of the Study:

  • To investigate and compare subjective and objective sleep patterns in children with different Attention-Deficit/Hyperactivity Disorder (ADHD) presentations.
  • To determine if ADHD subtype influences sleep quantity, quality, or fragmentation.

Main Methods:

  • 92 children (aged 7-11) diagnosed with ADHD (Inattentive, Hyperactive/Impulsive, Combined) were assessed.
  • Subjective sleep was measured using the Pediatric Sleep Questionnaire (PSQ), Pediatric Daytime Sleepiness Scale (PDSS), and sleep diaries.
  • Objective sleep was evaluated using polysomnography to assess sleep quantity, quality, and fragmentation.

Main Results:

  • Subjective reports indicated impaired sleep in 12.7% of the children.
  • No significant differences in objective or subjective sleep variables were found across the different ADHD presentations.
  • Sleep fragmentation data suggested poorer sleep continuity in the ADHD-Hyperactive/Impulsive group, and sleep was found to be affected by age.

Conclusions:

  • Parent-reported sleep breathing problems and daytime sleepiness can occur in children with ADHD, irrespective of total sleep time or efficiency.
  • Sleep patterns in children with ADHD do not appear to significantly vary based on the specific ADHD presentation.
  • Sleep characteristics in children with ADHD demonstrate an age-related evolution.
