Event-related potentials and behavior performance scores in children with sleep-disordered breathing

Area of Science:

• Neuroscience
• Pediatrics
• Sleep Medicine

Background:

• Sleep-Disordered Breathing (SDB) affects children's development.
• Cognitive and behavioral impairments are potential consequences of SDB.
• Understanding these deficits is crucial for early intervention.

Purpose of the Study:

• To investigate cognitive impairments and behavioral abnormalities in children with SDB.
• Utilize Event-Related Potentials (ERPs), Continuous Performance Testing (CPT), and the Child Behavior Checklist (CBCL).

Main Methods:

• Recruited 108 children (6-8 years old), 54 with SDB and 54 controls.
• Administered CBCL and OSA-18 questionnaire.
• 19 SDB children and 19 controls underwent CPT and ERP analysis.

Main Results:

• No significant differences in CPT performance between SDB and control groups.
• SDB group showed altered ERP amplitudes (Go-P3, NoGo-N2) and latencies (Go-P3, NoGo-P3) in frontal regions.
• SDB boys had significantly higher CBCL scores in multiple behavioral domains.

Conclusions:

• Children with SDB exhibit cognitive deficits in conflict monitoring, attention, and inhibition, primarily in the frontal lobe.
• Inhibition dysfunction may link SDB and ADHD pathogenesis.
• Boys with SDB may present with more behavioral problems than girls.
