Insights

Developmental coordination disorder (DCD) impacts children

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Motor Control

Background:

  • Developmental coordination disorder (DCD) is a neurodevelopmental condition affecting motor execution and learning in children.
  • Children with DCD display varied motor signs, including fine/gross motor deficits, impaired balance, and sensorimotor coordination issues.
  • Prevalence estimates for DCD vary (1.8%-8%) based on diagnostic criteria and standardized motor assessments.

Purpose of the Study:

  • To summarize current understanding of Developmental Coordination Disorder (DCD).
  • To review proposed etiological hypotheses for DCD.
  • To highlight neuroimaging findings and therapeutic approaches for DCD.

Main Methods:

  • Review of existing literature on Developmental Coordination Disorder (DCD).
  • Analysis of hypotheses regarding visuospatial, procedural learning, internal modeling, and executive function deficits.
  • Synthesis of findings from scarce neuroimaging studies and meta-analyses of therapeutic interventions.

Main Results:

  • DCD is characterized by difficulties in executing coordinated motor actions and learning new motor tasks.
  • Potential underlying mechanisms include deficits in visuospatial functions, procedural learning, internal modeling, or executive functions.
  • Neuroimaging implicates parietal, frontal, and cerebellar cortices; meta-analyses support task-oriented therapies.

Conclusions:

  • Developmental Coordination Disorder (DCD) presents with diverse motor challenges impacting children's daily activities.
  • Understanding the neurobiological underpinnings is crucial for targeted interventions.
  • Task-oriented approaches show promise for improving motor performance in children with DCD.

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

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....

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

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.

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.

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...
