Insights

Autism Spectrum Disorder (ASD) affects 9.1% of infants with NICU stays. Risk factors include prematurity and respiratory support needs, highlighting the need for early screening in high-risk infants.

Area of Science:

  • Pediatric Neurology
  • Developmental Pediatrics
  • Neonatal Medicine

Background:

  • Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
  • Infants and children admitted to the Neonatal Intensive Care Unit (NICU) may face increased risks.
  • Identifying early indicators and risk factors for ASD in this population is crucial.

Purpose of the Study:

  • To determine the prevalence of ASD in children with a history of NICU admission.
  • To identify significant risk factors associated with ASD development in this cohort.
  • To explore neurophysiological markers using Auditory Brain Response (ABR) in relation to ASD.

Main Methods:

  • A cross-sectional study involving 66 pediatric outpatients under 3 years old with prior NICU admission.
  • Utilized the Childhood Autism Rating Scale-Second Edition (CARS-2St) questionnaire for ASD assessment.
  • Employed Auditory Brain Response (ABR) testing to evaluate auditory pathway function.

Main Results:

  • The prevalence of ASD was found to be 9.1% (6 out of 66 children).
  • Significant risk factors included premature rupture of membranes, prematurity, extended NICU stay duration, and need for respiratory support.
  • ABR testing revealed significantly increased latencies and intervals in children with ASD, indicating auditory pathway abnormalities.

Conclusions:

  • The study highlights a notable prevalence of ASD among children with a NICU history.
  • Early screening for ASD is recommended for infants and children with NICU admission, even without other apparent neurological signs.
  • Findings support further research into neurophysiological markers for early ASD detection in at-risk infants.

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.

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 Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
