title: Intellectual Profiles in Children With ADHD and Comorbid Learning and Motor Disorders.
abstract: Objective:Neurodevelopmental disorders, including Reading Disorder, Disorder of Written Expression, and Developmental Coordination Disorder, often co-occur with ADHD. Although research has identified increased functional impairment in the presence of these comorbid diagnoses, few direct comparisons of intellectual profiles have been conducted. Thus, the present study examined Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) profiles of children with ADHD alone and with comorbid neurodevelopmental disorders.Method:Participants included 296 children with ADHD, ADHD with Developmental Coordination Disorder, and ADHD with Reading Disorder and/or Disorder of Written Expression.Results:Comparisons of these groups suggests children with ADHD and language-based Learning Disorders have poorer working memory than children with only ADHD. Furthermore, children with ADHD and Developmental Coordination Disorder perform relatively better on verbal compared with perceptual reasoning indexes.Conclusion:These intellectual profiles may have utility in identifying cognitive weaknesses inherent to these disorders and may be used to guide treatment intervention.
