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.

Annotation: What electrical brain activity tells us about brain function that other techniques cannot tell us – a child psychiatric perspective / Tobias BANASCHEWSKI in Journal of Child Psychology and Psychiatry, 48-5 (May 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-5 (May 2007) . - p.415–435 Titre : Annotation: What electrical brain activity tells us about brain function that other techniques cannot tell us – a child psychiatric perspective Type de document : Texte imprimé et/ou numérique Auteurs : Tobias BANASCHEWSKI, Auteur ; Daniel BRANDEIS, Auteur Année de publication : 2007 Article en page(s) : p.415–435 Langues : Anglais (eng) Mots-clés : ADHD anorexia-nervosa anxiety autism childhood-onset-schizophrenia depression developmental-dyslexia EEG endophenotypes ERP fMRI neuropsychology obsessive-compulsive-disorder specific-language-disorder tic-disorder Index. décimale : PER Périodiques Résumé : Monitoring brain processes in real time requires genuine subsecond resolution to follow the typical timing and frequency of neural events. Non-invasive recordings of electric (EEG/ERP) and magnetic (MEG) fields provide this time resolution. They directly measure neural activations associated with a wide variety of brain states and processes, even during sleep or in infants. Mapping and source estimation can localise these time-varying activation patterns inside the brain. Methods: Recent EEG/ERP research on brain functions in the domains of attention and executive functioning, perception, memory, language, emotion and motor processing in ADHD, autism, childhood-onset schizophrenia, Tourette syndrome, specific language disorder and developmental dyslexia, anxiety, obsessive-compulsive disorder, and depression is reviewed. Results: Over the past two decades, electrophysiology has substantially contributed to the understanding of brain functions during normal development, and psychiatric conditions of children and adolescents. Its time resolution has been important to measure covert processes, and to distinguish cause and effect. Conclusions: In the future, EEG/ERP parameters will increasingly characterise the interplay of neural states and information processing. They are particularly promising tools for multilevel investigations of etiological pathways and potential predictors of clinical treatment response.

Editorial Perspective: How should child psychologists and psychiatrists interpret FDA device approval? Caveat emptor / Martijn ARNS in Journal of Child Psychology and Psychiatry, 57-5 (May 2016)

The NEBA test relies upon an EEG-based measure, called the theta to beta ratio (TBR). Although this measure has yielded large differences between ADHD and non-ADHD groups in studies prior to 2009, recent studies and a meta-analysis could not replicate these findings. In this article, we have used the NEBA device as an exemplar for a discussion that distinguishes between FDA de novo marketing approval for a device and any claims that that device is empirically supported, scientifically validated with replicated findings. It is understood that the aims of each differ; however, for many, including the lay public as well as some mental health professionals, these terms may be confused and treated as though they are synonymous. With regard to the TBR measure, there is no reliable association or replication for its clinical usage in the ADHD diagnostic process. The recommendation for potential consumers of the NEBA Health test (as well as perhaps for other existing FDA-approved diagnostic tests) is caveat emptor (let the buyer beware!).

Genetics of preparation and response control in ADHD: the role of DRD4 and DAT1 / Björn ALBRECHT in Journal of Child Psychology and Psychiatry, 55-8 (August 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-8 (August 2014) . - p.914-923 Titre : Genetics of preparation and response control in ADHD: the role of DRD4 and DAT1 Type de document : Texte imprimé et/ou numérique Auteurs : Björn ALBRECHT, Auteur ; Daniel BRANDEIS, Auteur ; Henrik Uebel VON SANDERSLEBEN, Auteur ; Lilian VALKO, Auteur ; Hartmut HEINRICH, Auteur ; Xiaohui XU, Auteur ; Renate DRECHSLER, Auteur ; Alexander HEISE, Auteur ; Jonna KUNTSI, Auteur ; Ueli C.

The aim of this study was to clarify the impact of dopamine receptor D4 (DRD4) and dopamine transporter (DAT1) gene polymorphisms on these processes in ADHD and control children. Methods Behavioural and electrophysiological parameters from cued continuous performance tests with low and high attentional load were assessed in boys with ADHD combined type (N = 94) and controls without family history of ADHD (N = 31). Both groups were split for the presence of at least one DRD4 7-repeat allele and the DAT1 10-6 haplotype. Results Children with ADHD showed diminished performance and lower Cue-P3, CNV and Nogo-P3 amplitudes. Children with DRD4 7R showed similar performance problems and lower Cue-P3 and CNV, but Nogo-P3 was not reduced. Children with the DAT1 10-6 haplotype had no difficulties with performance or Cue-P3 and CNV, but contrary to expectations increased Nogo-P3. There were no Genotype by ADHD interactions. Conclusions This study detected specific effects of DRD4 7R on performance and brain activity related to attentional orienting and response preparation, while DAT1 10-6 was associated with elevated brain activity related to inhibitory response control, which potentially compensates increased impulsivity. As these genotype effects were additive to the impact of ADHD, the current results indicate that DRD4 and DAT1 polymorphisms are functionally relevant risk factors for ADHD and presumably other disorders sharing these endophenotypes.

Mothers' prenatal stress and their children's antisocial outcomes – a moderating role for the Dopamine D4 Receptor (DRD4) gene / Katrin ZOHSEL in Journal of Child Psychology and Psychiatry, 55-1 (January 2014)

This effect has been interpreted in terms of ‘fetal programming’. The 7-repeat (7r) allele of a VNTR polymorphism in exon III of the human dopamine receptor D4 (DRD4) has consistently been associated with externalizing behavior problems, especially in the presence of adverse environmental factors. So far, it is not known whether the DRD4 genotype moderates the effect of prenatal maternal stress on the development of childhood antisocial behavior. Methods As part of an ongoing epidemiological cohort study, prenatal maternal stress was assessed using self-report 3 months following child birth. When children were 8, 11, and 15 years old, mothers rated their children's externalizing behavior, and diagnoses of conduct disorder and/or oppositional defiant disorder (CD/ODD) according to DSM-IV were obtained. In a sample of N = 308 participants, the effects of the DRD4 genotype, prenatal maternal stress, and the interaction thereof on antisocial outcome were tested. Results Under conditions of elevated prenatal maternal stress, children carrying one or two DRD4 7r alleles were at increased risk of a diagnosis of CD/ODD. Moreover, homozygous carriers of the DRD4 7r allele displayed more externalizing behavior following exposure to higher levels of prenatal maternal stress, while homozygous carriers of the DRD4 4r allele turned out to be insensitive to the effects of prenatal stress. Conclusions This study is the first to report a gene–environment interaction related to DRD4 and prenatal maternal stress using data from a prospective study, which extends earlier findings on the impact of prenatal maternal stress with respect to childhood antisocial behavior.
