Self-Regulation and Inhibition in Comorbid ADHD Children: An Evaluation of Executive Functions

Abstract

The relationship between executive function and comorbid diagnoses in ADHD children is examined. One hundred six children between 7 and 15 years of age are assessed using the Tower of London (TOL), a test of executive function, and the Kiddie Schedule of Affective Disorders and Schizophrenia, Present and Lifetime Version, a diagnostic interview. All children met the diagnostic criteria for ADHD. A majority of the children had comorbid anxiety disorders, mood disorders, or oppositional defiant disorder. Measures on the TOL are total move score, total initiation time, and total rule violations. Age is predictive in all three measures of executive function as assessed by the TOL. Gender is predictive of total initiation time and total rule violations. Comorbid disorders are found to not have significance on executive function as measured by the TOL. This study concludes that comorbid disorders may not affect executive function.

Executive Function Deficits in Children with Attention-Deficit/Hyperactivity Disorder and Improvement with Lisdexamfetamine Dimesylate in an Open-Label Study

“…EF deficits have been found in patients with other neuropsychiatric disorders such as depression (DeBattista 2005), bipolar disorder (Quraishi and Frangou 2002;Doyle et al 2005), and high-functioning autism Verté et al 2005). However, there is no clear interrelationship between comorbid neuropsychiatric disorders and the occurrence or severity of EF deficits Oosterlaan et al 2005;Sarkis et al 2005). The findings of this study suggest that improvement in EF behavioral deficits with LDX treatment are not significantly affected by the presence or absence of comorbid psychiatric symptoms.…”

“…En effet, les performances observées à la (Meyers & Meyers, 1995;Strauss et al, 2006). Quant à la Tour de Londres, conçue de manière à évaluer les capacités executives de planification et de résolution de problèmes (Shallice, 1982;Strauss et al, 2006), elle sollicite également les capacités de mémoire de travail (Asato et al, 2006;Lezak et al, 2004;Pulos & Denzine, 2005) et les processus inhibiteurs (Culbertson & Zillmer, 1998a, 1998bKaller, Unterrainer, Rahm, & Halsband, 2004;Newman & Pittman, 2007;Sarkis, Sarkis, Marshall, & Archer, 2005). Ainsi, certains chercheurs ont observé la présence de …”

“…reprend l'affirmation selon laquelle l'épreuve de la Tour de Londres ne présente pas une sensibilité discriminante suffisante auprès de la clientèle adolescente faisant un usage abusif de psychotropes (Sarkis et al, 2005). Dans sa forme originale, la Tour de Londres est conçue de façon à ce que l'augmentation du nombre de déplacements nécessaires à la résolution d'un problème donné (c.-à-d., de deux à six mouvements) accroisse d'autant la difficulté de l'item en question (Krikorian et al, 1994;Shallice, 1982).…”

Development of Executive Functions in 5- to 12- Years old Iranian Children with and without ADHD

“…Considering the fact that ADHD costs millions a year in treatment and has lasting effects into adulthood, it is imperative that it should be studied more thoroughly (Sarkis, Sarkis, Marshall, & Archer, 2005). Although ADHD is one of the most commonly diagnosed mental disorders (Conners & Jett, 1999).…”

“…Although ADHD is one of the most commonly diagnosed mental disorders (Conners & Jett, 1999). If a relationship can be determined between ADHD and the executive functions, new interventions may be developed, and more effective medication can be prescribed (Sarkis et al, 2005).…”
