Developmental coordination disorder. The diagnosis of dyspraxia or developmental coordination disorder is based on motor coordination skills significantly below the expected level for the age of the child, assessed by a validated and standardized motor skills scale. This deficit must have an impact on activities of daily life, leisure and academic achievement. It should not be secondary to a neurological condition. It is a common disorder with a prevalence around 5%. The diagnosis is based on questioning of the family and the child, a clinical examination and an evaluation with standardized tools of motor skills and writing. It requires the intervention of a doctor, if possible trained in neurodevelopmental disorders, and of an occupational therapist. Interventions should focus on activities that are essential to the child's daily and school life.
