Sleep Disorders in Children With Autism Spectrum Disorder: Insights From Animal Models, Especially Non-human Primate...

Area of Science:

• Neurodevelopmental disorders
• Sleep science
• Animal modeling

Background:

• Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by social, communication, and behavioral challenges.
• Increased prevalence of ASD in children highlights the need to understand associated health issues, particularly sleep disturbances.
• Sleep is crucial for brain development, plasticity, and overall well-being, making sleep problems in ASD a significant concern.

Purpose of the Study:

• To review and discuss sleep disorders in children diagnosed with Autism Spectrum Disorder (ASD).
• To evaluate the prevalence, clinical features, and underlying pathophysiological mechanisms of sleep disturbances in ASD.
• To explore the utility and future directions of animal models in studying ASD-related sleep disorders.

Main Methods:

• Literature review of studies on sleep disorders in children with ASD.
• Analysis of prevalence data, clinical characteristics, and phenotypic aspects of ASD.
• Examination of existing rodent and non-human primate models of ASD and their relevance to sleep disturbances.

Main Results:

• Children with ASD exhibit a higher incidence of sleep problems compared to neurotypical children.
• Sleep disorders in ASD are linked to core symptoms and can manifest in various ways, including difficulty falling asleep, staying asleep, and altered sleep architecture.
• Animal models of ASD often display early-onset sleep abnormalities, providing valuable platforms for mechanistic research.

Conclusions:

• Sleep disturbances are a common and significant comorbidity in Autism Spectrum Disorder.
• Understanding the specific sleep issues and their brain mechanisms in ASD is crucial for improving quality of life.
• Animal models offer promising avenues for investigating the etiology and potential therapeutic targets for sleep disorders in ASD.
