Insights

Children with developmental disorders often have multiple conditions. This study explores how sensory-motor deficits link to developmental coordination disorder (DCD) and autistic disorder, offering insights into comorbidity.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatrics

Background:

  • Childhood developmental disorders frequently co-occur, a phenomenon known as comorbidity.
  • The underlying mechanisms driving high comorbidity rates in developmental disorders remain poorly understood.
  • Sensory-motor deficits have been historically linked to motor impairments in conditions like developmental coordination disorder (DCD).

Purpose of the Study:

  • To investigate the relationship between sensory-motor deficits and developmental disorders, including DCD, attention deficit hyperactivity disorder (ADHD), and autistic disorder.
  • To determine the role of sensory-motor functioning in differentiating between these developmental disorders.
  • To explore how sensory-motor deficits in DCD and autistic disorder may contribute to social difficulties.

Main Methods:

  • Critical review of existing literature on sensory-motor functioning and developmental disorders.
  • Analysis of recent research findings on sensory-motor deficits in children with DCD, ADHD, and autistic disorder.
  • Examination of the discriminative value of sensory-motor deficits across different diagnostic groups.

Main Results:

  • Poor sensory-motor integration is strongly associated with developmental coordination disorder (DCD).
  • Sensory-motor deficits are not significantly linked to attention deficit hyperactivity disorder (ADHD).
  • Sensory-motor impairments in children with DCD and autistic disorder may explain some observed social challenges.

Conclusions:

  • The significance of sensory-motor functioning in understanding and differentiating childhood developmental disorders has been underestimated.
  • Addressing sensory-motor deficits may be crucial for understanding the complex nature of comorbidity in developmental disorders.
  • This research enhances comprehension of the interconnectedness of developmental disorders and their associated challenges.

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.
Autism Spectrum Disorder01:19

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.
Oppositional Defiant Disorder01:30

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.

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.

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;...
Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Participant modeling involves therapists demonstrating calm and effective behaviors in situations...
