ADHD- and medication-related brain activation effects in concordantly affected parent–child dyads with ADHD / Jeffery N. EPSTEIN in Journal of Child Psychology and Psychiatry, 48-9 (September 2007)

Our objective was to examine functional brain abnormalities among youths and adults with ADHD and to examine the relations between these neurobiological abnormalities and response to stimulant medication. Method: A group of concordantly diagnosed ADHD parent–child dyads was compared to a matched sample of normal parent–child dyads. In addition, ADHD dyads were administered double-blind methylphenidate and placebo in a counterbalanced fashion over two consecutive days of testing. Frontostriatal function was measured using functional magnetic resonance imaging (fMRI) during performance of a go/no-go task. Results: Youths and adults with ADHD showed attenuated activity in fronto-striatal regions. In addition, adults with ADHD appeared to activate non-fronto-striatal regions more than normals. A stimulant medication trial showed that among youths, stimulant medication increased activation in fronto-striatal and cerebellar regions. In adults with ADHD, increases in activation were observed in the striatum and cerebellum, but not in prefrontal regions. Conclusions: This study extends findings of fronto-striatal dysfunction to adults with ADHD and highlights the importance of frontostriatal and frontocerebellar circuitry in this disorder, providing evidence of an endophenotype for examining the genetics of ADHD.

Assessing medication effects in the MTA study using neuropsychological outcomes / Jeffery N. EPSTEIN in Journal of Child Psychology and Psychiatry, 47-5 (May 2006)

Methods: 316 children who participated in the Multimodal Treatment Study of Children with ADHD (MTA) completed the Conners' Continuous Performance Test (CPT) at the 24-month assessment point. Outcome measures included standard CPT outcomes (e.g., errors of commission, mean hit reaction time (RT)) and RT indicators derived from an Ex-Gaussian distributional model (i.e., mu, sigma, and tau). Results: Analyses revealed significant effects of medication across all neuropsychological outcome measures. Results on the Ex-Gaussian outcome measures revealed that stimulant medication slows RT and reduces RT variability. Conclusions: This demonstrates the importance of including analytic strategies that can accurately model the actual distributional pattern, including the positive skew. Further, the results of the study relate to several theoretical models of ADHD.

Cognitive Measures of Adolescent Depression: Unique or Unitary Constructs? / Golda S. GINSBURG in Journal of Clinical Child & Adolescent Psychology, 38-6 (November-December 2009)  

Public ISBD [article]  inJournal of Clinical Child & Adolescent Psychology > 38-6 (November-December 2009) . - p.790-802 Titre : Cognitive Measures of Adolescent Depression: Unique or Unitary Constructs?

REINECKE, Auteur ; Julie NEWMAN KINGERY, Auteur ; Susan G. SILVA, Auteur ; Rick H. HOYLE, Auteur ; Rachel H. JACOBS, Auteur Année de publication : 2009 Article en page(s) : p.790-802 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The factor structure of several self-report questionnaires assessing depression-relevant cognitions frequently employed in clinical research was examined in a sample of 390 adolescents (M age = 14.54; 216 girls; 74% Caucasian) with current major depressive disorder enrolled in the Treatment of Adolescents with Depression Study. A four-factor solution resulted, accounting for 65% of the total variance. The factors were labeled (a) Cognitive Distortions and Maladaptive Beliefs, (b) Cognitive Avoidance, (c) Positive Outlook, and (d) Solution-Focused Thinking. Internal consistencies for the factor-based composite scores were .83, .85, .84, and .82, respectively. Girls endorsed more negative cognitions than boys on three of the four factors. Maladaptive cognitions were positively related to severity of depression and predicted treatment response. Taken together, findings indicated that there are four distinct domains of cognitions that are present among adolescents with depression that are tapped by several widely used self-report measures of cognitions.
