Insights
Developmental Coordination Disorder (DCD) affects 5-6% of children, impacting daily activities and academics due to motor skill deficits. This review covers DCD
Area of Science:
- Neurology
- Developmental Pediatrics
- Occupational Therapy
Background:
- Developmental Coordination Disorder (DCD) is a prevalent neuromotor disability affecting 5-6% of school-aged children.
- It is characterized by significant difficulties in motor coordination that interfere with daily living and academic tasks.
Observation:
- Children with DCD exhibit challenges in both fine and gross motor skills.
- Their motor performance is often slower, less accurate, and more variable compared to peers.
Findings:
- This review synthesizes the history of DCD definitions, prevalence, etiology, and comorbidities.
- It examines the impact of DCD on children's lives, prognosis, and current interventions.
- Recent neuroimaging findings in children with DCD are also discussed.
Implications:
- Understanding DCD's multifaceted nature is crucial for effective early intervention and support.
- This comprehensive review aids clinicians and researchers in diagnosing and managing DCD.
- Further research, including neuroimaging, can illuminate DCD's underlying mechanisms and inform treatment strategies.
Abstract:
Present in approximately 5-6% of school-aged children, developmental coordination disorder (DCD) is a neuromotor disability in which a child's motor coordination difficulties significantly interfere with activities of daily living or academic achievement. These children typically have difficulty with fine and/or gross motor skills, with motor performance that is usually slower, less accurate, and more variable than that of their peers. In this paper, we review the history of various definitions leading up to the current definition of DCD, prevalence estimates for the disorder, etiology, common co-morbidities, the impact of DCD on the child's life, and prognosis. As well, we briefly describe current interventions for children with the disorder and results of recent neuroimaging studies of the brains of children with DCD, including research by the authors of this paper.

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