This study aims to define the executive dysfunctions in attention deficit hyperactivity disorder (ADHD) and, specifically, in the inattentive and combined subtypes. Moreover, it intends to determine whether either the symptoms of inattention or those of hyperactivity/impulsivity of the disorder are related to these dysfunctions. Using the BRIEF (Behavior Rating Inventory of Executive Function), a total of 87 children were assessed and classified in three groups: 29 children with inattentive ADHD, 29 children with combined ADHD, and a control group of 29 children without ADHD. The results show that the children with ADHD differ from the control group in all dimensions of the BRIEF. The differences between ADHD types were more marked in behavioral than in cognitive aspects, the combined type being most affected. Furthermore, inattention symptoms appeared to be more specifically related to the BRIEF.
Este estudio trata de definir las disfunciones ejecutivas implicadas en el trastorno de déficit de atención con hiperactividad (TDAH) y, concretamente, en los tipos inatento y combinado. Además, pretende determinar si son los síntomas de inatención o los de hiperactividad/impulsividad de este trastorno los que están relacionados con dichas disfunciones. Mediante la escala Behavior Rating Inventory of Executive Function (BRIEF) se evaluaron 87 niños y se clasificaron en tres grupos: 29 con TDAH inatento, 29 con TDAH combinado, y 29 sin TDAH (grupo de control). Los resultados muestran que los niños con TDAH se diferencian del grupo de control en todas las dimensiones de la escala BRIEF. Las diferencias entre los tipos de TDAH estuvieron centradas en los aspectos comportamentales más que en los cognitivos, siendo el tipo combinado el más afectado. Además, son los síntomas de inatención los que están relacionados, en mayor medida, con la escala BRIEF.
