Sleep disorders in childhood: a review

Area of Science:

• Pediatric Sleep Medicine
• Neurodevelopmental Disorders
• Child Psychology

Background:

• Sleep patterns significantly change from infancy through adolescence, complicating the definition of childhood sleep disorders.
• Parasomnias are the most common childhood sleep disorders, often familial and linked to central nervous system (CNS) immaturity.
• Conditions like narcolepsy and obstructive sleep apnea (OSAS) can manifest in childhood, presenting unique challenges due to ongoing CNS development.

Purpose of the Study:

• To review and synthesize current understanding of sleep disorders in children.
• To highlight the diagnostic difficulties arising from developmental variations in sleep architecture.
• To discuss the prevalence, characteristics, and potential neurodevelopmental implications of common childhood sleep disorders.

Main Methods:

• Literature review of studies on childhood sleep disorders over the past decade.
• Analysis of developmental changes in sleep patterns from birth to adolescence.
• Categorization and description of prevalent sleep disorders including parasomnias, narcolepsy, and OSAS.

Main Results:

• Sleep patterns vary significantly with age, impacting disorder definition.
• Parasomnias (arousal disorders, somnambulism, somniloquy) are frequent and often familial.
• Nocturnal enuresis is common, and narcolepsy/OSAS symptoms can appear in childhood with CNS maturational influences.

Conclusions:

• Accurate diagnosis of childhood sleep disorders requires consideration of developmental stage.
• Parasomnias are common and often linked to CNS immaturity.
• Early identification and understanding of narcolepsy and OSAS in children are crucial for managing associated neurobehavioral complications.
