Performance on Executive Functions and Comorbid Associated Symptoms in Children with Attention Deficit Hyperactivity Disorder (ADHD)

The aim of this study was to analyze the performance of executive functions in children with Attention deficit hyperactivity disorder based on internalizing and externalizing associated comorbid symptoms. 45 children aged 8 to 14 with ADHD were assessed with executive function tests. The results showed that the group of children with internalizing symptoms has underperformed in relation to organization and planning and motor inhibition, and the group of children with externalizing symptoms underperformed motor inhibition compared to children without comorbid symptoms, which would indicate that the analyzed variables allow collaborating with the diagnostic evaluation process of the disorder. Be able to describe the executive function disorder performance in relation to various comorbid associations would enable a better understanding of the entity and an adequate differential diagnosis.
