Altered intrinsic functional connectivity of the cingulate cortex in children with severe temper outbursts / Amy Krain ROY in Development and Psychopathology, 30-2 (May 2018)  

Public ISBD [article]  inDevelopment and Psychopathology > 30-2 (May 2018) . - p.571-579 Titre : Altered intrinsic functional connectivity of the cingulate cortex in children with severe temper outbursts Type de document : Texte imprimé et/ou numérique Auteurs : Amy Krain ROY, Auteur ; Randi BENNETT, Auteur ; Jonathan POSNER, Auteur ; Leslie HULVERSHORN, Auteur ; Francisco Xavier CASTELLANOS, Auteur ; Rachel G. KLEIN, Auteur Article en page(s) : p.571-579 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Severe temper outbursts (STO) in children are associated with impaired school and family functioning and may contribute to negative outcomes. These outbursts can be conceptualized as excessive frustration responses reflecting reduced emotion regulation capacity. The anterior cingulate cortex (ACC) has been implicated in negative affect as well as emotional control, and exhibits disrupted function in children with elevated irritability and outbursts. This study examined the intrinsic functional connectivity (iFC) of a region of the ACC, the anterior midcingulate cortex (aMCC), in 5- to 9-year-old children with STO (n = 20), comparing them to children with attention-deficit/hyperactivity disorder (ADHD) without outbursts (ADHD; n = 18). Additional analyses compared results to a sample of healthy children (HC; n = 18) and examined specific associations with behavioral and emotional dysregulation. Compared to the ADHD group, STO children exhibited reduced iFC between the aMCC and surrounding regions of the ACC, and increased iFC between the aMCC and precuneus. These differences were also seen between the STO and HC groups; ADHD and HC groups did not differ. Specificity analyses found associations between aMCC–ACC connectivity and hyperactivity, and between aMCC–precuneus iFC and emotion dysregulation. Disruption in aMCC networks may underlie the behavioral and emotional dysregulation characteristic of children with STO.

An fMRI examination of developmental differences in the neural correlates of uncertainty and decision-making / Amy L. KRAIN in Journal of Child Psychology and Psychiatry, 47-10 (October 2006)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 47-10 (October 2006) . - p.1023–1030 Titre : An fMRI examination of developmental differences in the neural correlates of uncertainty and decision-making Type de document : Texte imprimé et/ou numérique Auteurs : Amy L. KRAIN, Auteur ; Daniel Samuel PINE, Auteur ; Sara HEFTON, Auteur ; Monique ERNST, Auteur ; Rachel G. KLEIN, Auteur ; Michael P. MILHAM, Auteur ; Francisco Xavier CASTELLANOS, Auteur Année de publication : 2007 Article en page(s) : p.1023–1030 Langues : Anglais (eng) Mots-clés : Adolescence anxiety brain-imaging development Index. décimale : PER Périodiques Résumé : Background: Maturation of prefrontal circuits during adolescence contributes to the development of cognitive processes such as decision-making. Recent theories suggest that these neural changes also play a role in the shift from generalized anxiety disorder (GAD) to depression that often occurs during this developmental period. Cognitive models of the development of GAD highlight the role of intolerance of uncertainty (IU), which can be characterized behaviorally by impairments in decision-making. The present study examines potential developmental differences in frontal regions associated with uncertain decision-making, and tests the impact of IU on these circuits. Methods: Twelve healthy adults (ages 19–36) and 12 healthy adolescents (ages 13–17) completed a decision-making task with conditions of varied uncertainty while fMRI scans were acquired. They also completed measures of worry and IU, and a questionnaire about their levels of anxiety and certainty during the task. Results: Combined group analyses demonstrated significant linear effects of uncertainty on activity within anterior cingulate cortex (ACC). Region of interest (ROI)-based analysis found a significant interaction of group and IU ratings in ACC. Increased IU was associated with robust linear increases in ACC activity only in adolescents. An ROI analysis of feedback-related processing found that adolescents demonstrated greater activation during incorrect trials relative to correct trials, while the adults showed no difference in neural activity associated with incorrect and correct feedback. Conclusions: This decision-making task was shown to be effective at eliciting uncertainty-related ACC activity in adults and adolescents. Further, IU impacts ACC activity in adolescents during uncertain decision-making, providing preliminary support for a developmental model of GAD.

Here, we performed the largest ever analysis of brain left-right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. Methods We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 unaffected controls. Asymmetry Indexes (AIs) were calculated per participant for each bilaterally paired measure, and linear mixed effects modeling was applied separately in children, adolescents, adults, and the total sample, to test exhaustively for potential associations of ADHD with structural brain asymmetries. Results There was no evidence for altered caudate nucleus asymmetry in ADHD, in contrast to prior literature. In children, there was less rightward asymmetry of the total hemispheric surface area compared to controls (t = 2.1, p = .04). Lower rightward asymmetry of medial orbitofrontal cortex surface area in ADHD (t = 2.7, p = .01) was similar to a recent finding for autism spectrum disorder. There were also some differences in cortical thickness asymmetry across age groups. In adults with ADHD, globus pallidus asymmetry was altered compared to those without ADHD. However, all effects were small (Cohen’s d from ?0.18 to 0.18) and would not survive study-wide correction for multiple testing. Conclusion Prior studies of altered structural brain asymmetry in ADHD were likely underpowered to detect the small effects reported here. Altered structural asymmetry is unlikely to provide a useful biomarker for ADHD, but may provide neurobiological insights into the trait.

Increased awareness of the mismatch between categorical classifications and the complexity of biological systems drives the search for novel frameworks including discovery science in Big Data. In this review, we provide an overview of incipient approaches, primarily focused on classically categorical diagnoses such as schizophrenia (SZ), autism spectrum disorder (ASD), and attention-deficit/hyperactivity disorder (ADHD), but also reference convincing, if focal, advances in cancer biology, to describe the challenges of Big Data and discovery science, and outline approaches being formulated to overcome existing obstacles. Findings A paradigm shift from categorical diagnoses to a domain/structure-based nosology and from linear causal chains to complex causal network models of brain–behavior relationship is ongoing. This (r)evolution involves appreciating the complexity, dimensionality, and heterogeneity of neuropsychiatric data collected from multiple sources (‘broad’ data) along with data obtained at multiple levels of analysis, ranging from genes to molecules, cells, circuits, and behaviors (‘deep’ data). Both of these types of Big Data landscapes require the use and development of robust and powerful informatics and statistical approaches. Thus, we describe Big Data analysis pipelines and the promise and potential limitations in using Big Data approaches to study psychiatric disorders. Conclusions We highlight key resources available for psychopathological studies and call for the application and development of Big Data approaches to dissect the causes and mechanisms of neuropsychiatric disorders and identify corresponding biomarkers for early diagnosis.
