Insights

Children born extremely preterm (EPT) and very preterm (VPT) face higher risks of neurodevelopmental issues. These preterm infants often experience multiple domain impairments, impacting their development.

Area of Science:

  • Pediatric neurology
  • Developmental psychology
  • Public health

Background:

  • Preterm birth is a significant concern for child health and education.
  • Neurodevelopmental outcomes in extremely preterm (EPT) and very preterm (VPT) children require thorough investigation.

Purpose of the Study:

  • To assess neuromotor, cognitive, language, and emotional/behavioral outcomes in 4-year-old children born EPT (23-27 weeks), VPT (28-33 weeks), and full term (FT: 38-41 weeks).
  • To identify risks of impairment across multiple neurodevelopmental domains in preterm populations.

Main Methods:

  • Prospective longitudinal study of 105 VPT and 107 FT children born 1998-2000.
  • Comprehensive multidisciplinary assessment at 4 years corrected age, including neurological examination, cognitive and language testing, and emotional/behavioral assessment.

Main Results:

  • EPT and VPT children showed significantly higher risks of cerebral palsy, cognitive delay, language delay, and emotional/behavioral problems compared to FT children.
  • Children born EPT and VPT were three times more likely to have impairments in multiple neurodevelopmental domains than FT children.
  • Specific risks: Cerebral palsy (EPT 18%, VPT 15%), Cognitive delay (EPT 33%, VPT 36%), Language delay (EPT 29%, VPT 29%), Emotional/behavioral problems (EPT 37%, VPT 13%).

Conclusions:

  • A significant proportion of preschool children born preterm exhibit clinically significant neurodevelopmental problems.
  • Impairment across multiple domains is common in preterm survivors.
  • Monitoring preschool development across various domains is crucial, considering the cascading effects of multiple impairments.

Attention-Deficit/Hyperactivity Disorder01:30

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.
Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
