Insights

Children with autism spectrum disorder (ASD) have nearly double the risk of sleep disorder diagnoses, including sleep-disordered breathing (SDB). They also face higher rates of diagnostic tests and surgeries for these conditions compared to neurotypical children.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders

Background:

  • Sleep disorders are prevalent in children with autism spectrum disorder (ASD), exacerbating cognitive and behavioral challenges.
  • Sleep-disordered breathing (SDB) is a treatable condition linked to behavioral issues in children.

Purpose of the Study:

  • To compare the risk of sleep disorder diagnoses, including SDB, in children with ASD versus controls.
  • To assess the relative risk of diagnostic and surgical procedures for sleep disorders in children with ASD.

Main Methods:

  • Retrospective case-cohort study of 48,762 children with ASD (ages 2-18) within the military health system (2000-2013).
  • Matched 1:5 with children without ASD by birthdate, sex, and enrollment.
  • Analyzed ICD-9-CM and CPT codes for sleep disorders and related procedures; calculated relative risks (RR) using conditional Poisson regression.

Main Results:

  • Children with ASD showed a significantly higher risk for any sleep disorder diagnosis (RR: 1.97) and SDB (RR: 1.96).
  • Increased risk observed for polysomnography (RR: 3.74) and sleep disorder-related surgeries (RR: 1.50) in children with ASD.

Conclusions:

  • Children with ASD are at elevated risk for sleep disorders, including SDB.
  • They are more likely to undergo diagnostic evaluations and surgical interventions for sleep conditions compared to their peers without ASD.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
