Sleep disorder in children with autism

Area of Science:

• Developmental Psychology
• Pediatric Neurology
• Autism Spectrum Disorder Research

Background:

• Autism Spectrum Disorder (ASD) is a neurodevelopmental condition impacting social interaction and communication.
• Sleep disturbances are frequently reported in children with ASD, but prevalence and specific patterns require further investigation.
• Understanding sleep patterns in autistic children is crucial for improving quality of life for both children and their families.

Purpose of the Study:

• To investigate the prevalence and characteristics of sleep disorders in a cohort of children with autism.
• To identify common types of sleep disturbances and their onset in young autistic children.
• To determine the typical age of resolution for sleep disorders in this population.

Main Methods:

• A questionnaire-based survey was administered to 88 children diagnosed with autism living in a Tokyo suburb.
• Data collection occurred between July 21 and August 31.
• Information gathered included the presence of sleep disorders, age of onset, specific sleep problems, and co-occurring issues like bed-wetting.

Main Results:

• Sleep disorders were reported in 56 out of 88 (63.6%) autistic children.
• A significant majority (44 children) experienced sleep disorders before the age of three.
• The most frequent sleep issues were difficulty falling asleep (23 children), frequent nighttime awakenings (19 children), and early morning awakenings (11 children). Bed-wetting was noted in 22 children.
• The average age for the cessation of sleep disorders was five years old.

Conclusions:

• Sleep disorders represent a significant and common challenge for children with autism.
• Early-onset sleep disturbances are prevalent in this population, often starting before three years of age.
• While sleep problems frequently resolve by age five, specific interventions may be beneficial for persistent issues.
