Developmental coordination disorder in Swedish 7-year-old children
1Department of Child and Adolescent Psychiatry, Göteborg University, Sahlgren University Hospital, Sweden.
Summary
Developmental Coordination Disorder (DCD) affects nearly 14% of children, often co-occurring with ADHD. Early DCD diagnosis predicts later challenges, highlighting the need for clinical awareness and support.
Area of Science:
- Pediatric neurology
- Developmental psychology
- Child psychiatry
Background:
- Developmental Coordination Disorder (DCD) is a neurodevelopmental condition affecting motor skills.
- Understanding the prevalence, comorbidities, and long-term outcomes of DCD is crucial for early intervention.
Purpose of the Study:
- To determine the prevalence of DCD in 7-year-olds.
- To investigate the comorbidity of DCD with other conditions, particularly ADHD.
- To assess the long-term outcomes for children diagnosed with DCD.
Main Methods:
- A population-based study involving 7-year-old children.
- Individual examinations, teacher, and parent interviews were conducted.
- Follow-up assessments occurred at ages 8, 9, and 10 years.
Main Results:
- Severe DCD was identified in 4.9% and moderate DCD in 8.6% of children.
- Children with DCD showed significant associations with attention deficit symptoms, Asperger's disorder symptoms, and school dysfunction.
- Approximately 50% of children with DCD exhibited moderate to severe ADHD symptoms.
Conclusions:
- DCD is a prevalent condition with a strong association with ADHD.
- A DCD diagnosis at age 7 predicts persistent DCD at age 8 and reading comprehension difficulties at age 10.
- Clinicians require enhanced knowledge of DCD and its comorbidities to improve care for affected children.
