Abstract

Objective: The term apraxia is clearly understood in adult behavioral neurology, with assessment of gesture central to the diagnosis. In contrast, the concept of "developmental dyspraxia" has been more problematic. In an effort to better specify its potential significance, we describe preliminary practice-based evidence for understanding developmental dyspraxia acquired within a theoretical framework informed by both adult behavioral neurology and a neuroconstructivist appreciation of neurodevelopmental disorders. Specifically, we describe the experience of a diagnostic clinic for children with learning disorders that adopted this framework and compare clinical characteristics of children diagnosed with dyspraxia with those of children diagnosed with dyslexia during the same time period. Method: The dyspraxia diagnosis was based on the presence of impaired gesture and/or cognitive problems with planning. Over the target period, 71 children were diagnosed with dyspraxia and 114 children were diagnosed with dyslexia. Twenty-nine of the 71 children with dyspraxia were also diagnosed with dyslexia. Domains assessed included early developmental milestones, neurologic findings, cognition, speech and language, academic skills, and psychosocial functioning. Results: Compared to the dyslexia group, children with dyspraxia (with or without dyslexia) had more problems with speech and language planning and planning in everyday life. Children with dyspraxia without dyslexia had more frequent early motor delays and deficits in visuospatial production than the other groups. The dyslexia groups predictably demonstrated poorer single word reading and phonologic processing compared to the dyspraxia only group (all P < .01). Conclusions: A neurologic finding of impaired gesture in children with learning disorders may signal a broader neurodevelopmental profile of developmental dyspraxia with both theoretical relevance and meaningful implications for evaluation and treatment. Cognitive problems with planning are particularly relevant.
