Methods: Parent-reported behavior problems as assessed by the Child Behavior Checklist were used to form four groups of children with 1) neither internalizing nor externalizing problems (n = 1,470), 2) only internalizing problems (n = 237), 3) only externalizing problems (n = 182), and 4) both internalizing and externalizing problems (n = 148). These groups were compared on measures of speed and accuracy from the Amsterdam Neuropsychological Tasks program reflecting the efficiency of several input-, central cognitive-, and output-related information processing capacities. Results: Children with both internalizing and externalizing problems demonstrated the least efficient performance, followed by children with only externalizing problems, whereas children with only internalizing problems did not differ from children without problems. More specifically, response variability and the ability to maintain and quickly compare information in working memory were found to be related to the severity of problem behavior. The ability to inhibit prepotent responses was related to the type of problem behavior, discriminating between the children with only internalizing problems and only externalizing problems. However, this latter capacity no longer differentiated when controlling for IQ. No differences were found between boys and girls. Conclusions: The results suggest that, in general, cognitive processing deficits are more strongly related to the degree than to the type of maladaptive behavior. Furthermore, response variability and working memory may serve as potential markers for identifying high-risk children and response inhibition as an indicator of the type of maladaptive behavior.

Motor control in children with ADHD and non-affected siblings: deficits most pronounced using the left hand / Nanda N. ROMMELSE in Journal of Child Psychology and Psychiatry, 48-11 (November 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-11 (November 2007) . - p.1071–1079 Titre : Motor control in children with ADHD and non-affected siblings: deficits most pronounced using the left hand Type de document : Texte imprimé et/ou numérique Auteurs : Nanda N. ROMMELSE, Auteur ; Joseph A. SERGEANT, Auteur ; Leo M. J. DE SONNEVILLE, Auteur ; Jan K. BUITELAAR, Auteur ; Jaap OOSTERLAAN, Auteur ; Marieke E. ALTINK, Auteur ; Cathelijne J.M. BUSCHGENS, Auteur Année de publication : 2007 Article en page(s) : p.1071–1079 Langues : Anglais (eng) Mots-clés : ADHD non-affected-sibling motor-control endophenotype Index. décimale : PER Périodiques Résumé : Attention-deficit/hyperactivity disorder (ADHD) is strongly influenced by heritability. Identifying heritable vulnerability traits (endophenotypes) that mark a relatively high risk of developing the disorder can contribute to the identification of risk genes. A fruitful area for the search for such endophenotypes may be motor control in children with ADHD, since the disorder is frequently accompanied by motor problems. Method: The current study used a large sample of 350 children with ADHD, 195 non-affected siblings and 271 normal controls aged 5–19 years. Children were administered two computerised motor control tasks in which they had to trace a path between two circles (Tracking task) and follow a randomly moving target (Pursuit task). Both tasks were performed with both the right and the left hand. Results: Children with ADHD were less precise and stable than controls. Non-affected siblings also deviated from controls, but only on the Tracking task. Group differences were modulated by the use of the right versus the left hand: no group differences emerged when the right hand was used, yet group differences did emerge when the left hand was used. Performance on both tasks was significantly familial. Conclusions: Imprecision and instability of movements in children with ADHD and in their non-affected siblings as measured by the Tracking task might be suitable endophenotypic candidates: these deficits are familially present in children having ADHD as well as in their non-affected siblings. Motor performance might be best assessed in children using their left hand, because motor control deficits are most pronounced using the left hand. This might relate to right hemispheric brain pathology in children with ADHD (and possibly in their non-affected siblings) that is related to the control of the left hand and/or relate to differential effects of daily life practice on both hands, which may be smaller on the left hand.
