Insights

Developmental Coordination Disorder (DCD) affects 11.3% of children born very preterm at age 11, impacting cognition and quality of life. Despite challenges, their health-related quality of life exceeds general population norms.

Area of Science:

  • Pediatrics
  • Neurodevelopmental Disorders
  • Child Psychology

Background:

  • Children born very preterm face higher risks for neurodevelopmental challenges.
  • Developmental Coordination Disorder (DCD) is a common motor disorder affecting children's daily lives.
  • Understanding DCD's impact on cognition and quality of life in this population is crucial.

Purpose of the Study:

  • To determine the prevalence of DCD in children born very preterm at 11 years of age.
  • To investigate the correlation between DCD, cognitive function, and self-experienced health-related quality of life (HRQoL).
  • To compare the HRQoL of very preterm children with DCD to their peers and population norms.

Main Methods:

  • A prospective follow-up study of 170 children born very preterm in Finland.
  • Motor skills assessed using Movement Assessment Battery for Children - Second Edition (Movement ABC-2).
  • Cognitive abilities evaluated with Wechsler Intelligence Scale for Children - Fourth Edition (WISC-IV); HRQoL measured by the 17-Dimensional Illustrated Questionnaire (17D).

Main Results:

  • 11.3% of very preterm children were diagnosed with DCD (Movement ABC-2 score ≤5th percentile).
  • DCD correlated with poorer cognitive scores (Full-Scale IQ 76.8 vs 91.6, p=0.001) and lower self-reported HRQoL (17D 0.93 vs 0.96, p=0.03).
  • Despite lower HRQoL compared to peers without motor impairment, very preterm children reported better HRQoL than Finnish population norms (p<0.001).

Conclusions:

  • DCD remains prevalent at age 11 in children born very preterm.
  • DCD is associated with impaired cognitive development and reduced health-related quality of life.
  • Very preterm children, even with DCD, demonstrate a higher HRQoL compared to the general population.

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

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 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,...

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....

Introduction to Developmental Psychology01:27

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Learning Disabilities01:25

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
