Attentional functions in children and adolescents with ADHD, depressive disorders, and the comorbid condition / Thomas GUNTHER in Journal of Child Psychology and Psychiatry, 52-3 (March 2011)
[article]
Titre : Attentional functions in children and adolescents with ADHD, depressive disorders, and the comorbid condition Type de document : Texte imprimé et/ou numérique Auteurs : Thomas GUNTHER, Auteur ; Kerstin KONRAD, Auteur ; Stephane A. DE BRITO, Auteur ; Beate HERPERTZ-DAHLMANN, Auteur ; Timo D. VLOET, Auteur Année de publication : 2011 Article en page(s) : p.324-331 Langues : Anglais (eng) Mots-clés : ADHD depression attention neuropsychology Index. décimale : PER Périodiques Résumé : Background: Attention-deficit hyperactivity disorder (ADHD) and depressive disorders (DDs) often co-occur in children and adolescents, but evidence on the respective influence of these disorders on attention parameters is inconsistent. This study examines the influence of DDs on ADHD in a model-oriented approach that includes selectivity and intensity attention parameters.
Methods: Ten- to fifteen-year-olds with ADHD (n = 63), DDs (n = 61), ADHD+DDs (n = 64), and healthy controls (n = 64) completed a battery of tests including five neuropsychological tasks (i.e., alertness, sustained attention, divided attention, go/no-go, and attentional set-shifting).
Results: All clinical groups showed attentional problems, especially in more complex attentional tasks and in the intensity aspects of attention. We observed the most severe attentional impairments in children with ADHD that was independent from a comorbid DD.
Conclusion: The clinical groups were significantly different from the healthy control group, especially in more complex attentional tasks and in the intensity aspects of attention. Some differences between ADHD, DDs and ADHD+DDs groups were detected on neuropsychological attentional performance, but the effects were not strong enough to differentiate the clinical groups from each other.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02320.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=118

Titre : Emotional processing in male adolescents with childhood-onset conduct disorder Type de document : Texte imprimé et/ou numérique Auteurs : Sabine C. HERPERTZ, Auteur ; Beate HERPERTZ-DAHLMANN, Auteur ; Gereon R. FINK, Auteur ; Kerstin KONRAD, Auteur ; Thomas HUEBNER, Auteur ; Ivo MARX, Auteur ; Timo D. VLOET, Auteur ; Tony STOECKER, Auteur ; N. Jon SHAH, Auteur Année de publication : 2008 Article en page(s) : p.781 - 791 Langues : Anglais (eng) Mots-clés : Conduct-disorder fMRI emotion antisocial-behavior amygdala antisocial-personality-disorder Index. décimale : PER Périodiques Résumé : Background: Boys with early onset of conduct disorder (CD), most of whom also meet diagnostic criteria of a comorbid attention deficit hyperactivity disorder (ADHD), tend to exhibit high levels of aggression throughout development. While a number of functional neuroimaging studies on emotional processing have been performed in antisocial adults, little is known about how CD children process emotional information.
Method: Functional magnetic resonance imaging data were analyzed in 22 male adolescents aged 12 to 17 years with childhood-onset CD (16 of them with comorbid ADHD) compared to 22 age-matched male healthy controls. In order to consider the likely confounding of results through ADHD comorbidity, we performed a supplementary study including 13 adolescent subjects with pure ADHD who were compared with healthy controls. To challenge emotional processing of stimuli, a passive viewing task was applied, presenting pictures of negative, positive or neutral valence.
Results: When comparing CD/combined disorder patients with healthy controls, we found enhanced left-sided amygdala activation in response to negative pictures as compared to neutral pictures in the patient group. In addition, these boys exhibited no reduced activation in the orbitofrontal, anterior cingulate and insular cortices. By contrast, children with pure ADHD did not show any abnormalities in amygdala activation but showed decreased neural activity in the insula only in response to negative pictures.
Conclusions: Increased rather than reduced amygdala activation found in our study may indicate an enhanced response to environmental cues in adolescents with early-onset CD (most of whom also met the condition of ADHD), and is not consistent with the assumption of a reduced capacity to take note of affective information in the social environment. Further studies with an emphasis on developmental aspects of affect regulation are needed to clarify the relationship between CD and adult personality pathology associated with different modes of persistent antisocial behavior.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.01905.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=541
