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.

Annual Research Review: On the relations among self-regulation, self-control, executive functioning, effortful control, cognitive control, impulsivity, risk-taking, and inhibition for developmental psychopathology / Joel T. NIGG in Journal of Child Psychology and Psychiatry, 58-4 (April 2017)

NIGG, Auteur Article en page(s) : p.361-383 Langues : Anglais (eng) Mots-clés : Attention  self-control  executive function  impulsivity Index. décimale : PER Périodiques Résumé : Background Self-regulation (SR) is central to developmental psychopathology, but progress has been impeded by varying terminology and meanings across fields and literatures. Methods The present review attempts to move that discussion forward by noting key sources of prior confusion such as measurement-concept confounding, and then arguing the following major points. Results First, the field needs a domain-general construct of SR that encompasses SR of action, emotion, and cognition and involves both top-down and bottom-up regulatory processes. This does not assume a shared core process across emotion, action, and cognition, but is intended to provide clarity on the extent of various claims about kinds of SR. Second, top-down aspects of SR need to be integrated. These include (a) basic processes that develop early and address immediate conflict signals, such as cognitive control and effortful control (EC), and (b) complex cognition and strategies for addressing future conflict, represented by the regulatory application of complex aspects of executive functioning. Executive function (EF) and cognitive control are not identical to SR because they can be used for other activities, but account for top-down aspects of SR at the cognitive level. Third, impulsivity, risk-taking, and disinhibition are distinct although overlapping; a taxonomy of the kinds of breakdowns of SR associated with psychopathology requires their differentiation. Fourth, different aspects of the SR universe can be organized hierarchically in relation to granularity, development, and time. Low-level components assemble into high-level components. This hierarchical perspective is consistent across literatures. Conclusions It is hoped that the framework outlined here will facilitate integration and cross-talk among investigators working from different perspectives, and facilitate individual differences research on how SR relates to developmental psychopathology.

Annual Research Review: Perspectives on progress in ADHD science - from characterization to cause / Edmund J. S. SONUGA-BARKE in Journal of Child Psychology and Psychiatry, 64-4 (April 2023)

Over the past fifty years, scientific research has made enormous strides in characterizing the ADHD condition and in understanding its correlates and causes. However, the translation of these scientific insights into clinical benefits has been limited. In this review, we provide a selective and focused survey of the scientific field of ADHD, providing our personal perspectives on what constitutes the scientific consensus, important new leads to be highlighted, and the key outstanding questions to be addressed going forward. We cover two broad domains - clinical characterization and, risk factors, causal processes and neuro-biological pathways. Part one focuses on the developmental course of ADHD, co-occurring characteristics and conditions, and the functional impact of living with ADHD - including impairment, quality of life, and stigma. In part two, we explore genetic and environmental influences and putative mediating brain processes. In the final section, we reflect on the future of the ADHD construct in the light of cross-cutting scientific themes and recent conceptual reformulations that cast ADHD traits as part of a broader spectrum of neurodivergence.

Annual Research Review: Reaction time variability in ADHD and autism spectrum disorders: measurement and mechanisms of a proposed trans-diagnostic phenotype / Sarah L. KARALUNAS in Journal of Child Psychology and Psychiatry, 55-6 (June 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-6 (June 2014) . - p.685-710 Titre : Annual Research Review: Reaction time variability in ADHD and autism spectrum disorders: measurement and mechanisms of a proposed trans-diagnostic phenotype Type de document : Texte imprimé et/ou numérique Auteurs : Sarah L.

Scope and Methodology Using the examples of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASD), we discuss RT variability. We first present a new meta-analysis of RT variability in ASD with and without comorbid ADHD. We then discuss potential mechanisms that may account for RT variability and statistical models that disentangle the cognitive processes affecting RTs. We then report a second meta-analysis comparing ADHD and non-ADHD children on diffusion model parameters. We consider how findings inform the search for neural correlates of RT variability. Findings Results suggest that RT variability is increased in ASD only when children with comorbid ADHD are included in the sample. Furthermore, RT variability in ADHD is explained by moderate to large increases (d = 0.63–0.99) in the ex-Gaussian parameter ? and the diffusion parameter drift rate, as well as by smaller differences (d = 0.32) in the diffusion parameter of nondecision time. The former may suggest problems in state regulation or arousal and difficulty detecting signal from noise, whereas the latter may reflect contributions from deficits in motor organization or output. The neuroimaging literature converges with this multicomponent interpretation and also highlights the role of top-down control circuits. Conclusion We underscore the importance of considering the interactions between top-down control, state regulation (e.g. arousal), and motor preparation when interpreting RT variability and conclude that decomposition of the RT signal provides superior interpretive power and suggests mechanisms convergent with those implicated using other cognitive paradigms. We conclude with specific recommendations for the field for next steps in the study of RT variability in neurodevelopmental disorders.

Child ADHD and personality/temperament traits of reactive and effortful control, resiliency, and emotionality / Michelle M. MARTEL in Journal of Child Psychology and Psychiatry, 47-11 (November 2006)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 47-11 (November 2006) . - p.1175–1183 Titre : Child ADHD and personality/temperament traits of reactive and effortful control, resiliency, and emotionality Type de document : Texte imprimé et/ou numérique Auteurs : Michelle M. MARTEL, Auteur ; Joel T. NIGG, Auteur Année de publication : 2007 Article en page(s) : p.1175–1183 Langues : Anglais (eng) Mots-clés : Temperament personality ADHD psychopathology Index. décimale : PER Périodiques Résumé : Background: Models of attention-deficit/hyperactivity disorder (ADHD) suggest developmental influences may feed into components of the disorder separately from associated disruptive behavior problems. We investigated this in terms of key personality/temperament traits of Reactive and Effortful Control, Resiliency, and Emotionality. Methods: A sample of 179 children (age 6–12, 63% boys), of whom 92 had ADHD, 52 were Controls, and 35 were borderline or not otherwise specified cases of ADHD, were examined. Dispositional trait scores were derived from parent-completed California Q-sort and the Early Adolescent Temperament Questionnaire. Child ADHD symptoms were evaluated using maternal structured diagnostic interview and teacher-completed symptom ratings. Results: Traits were differentially associated with symptoms. Reactive Control was related to hyperactivity-impulsivity as rated by both parents and teachers. Negative Emotionality was related to oppositional-defiance. Resiliency was primarily related to inattention-disorganization as rated by both parents and teachers; Effortful Control was related uniquely to inattention in parent but not teacher data. A moderation effect emerged; the relationship between parent-rated Negative Emotionality and teacher-rated ADHD symptoms was stronger for children with high levels of both Reactive and Effortful Control. Conclusions: Results are interpreted in relation to a two-pathway model of ADHD; regulation problems contribute to the emergence of symptoms of inattention-disorganization, reactive or motivational control problems to the emergence of hyperactivity-impulsivity, and these are distinct from negative affectivity. Children with regulation deficits and a reactive motivational style are especially at risk for the development of ADHD.
