While both disorders are associated with lower IQ, recent twin data suggest that the shared genetic variability between reading difficulties and ADHD inattention symptoms is largely independent from genetic influences contributing to general cognitive ability. The current study aimed to extend the previous findings that were based on rating scale measures in a population sample by examining the generalisability of the findings to a clinical population, and by measuring reading difficulties both with a rating scale and with an objective task. This study investigated the familial relationships between ADHD, reading difficulties and IQ in a sample of individuals diagnosed with ADHD combined type, their siblings and control sibling pairs. Methods:  Multivariate familial models were run on data from 1,789 individuals at ages 6–19. Reading difficulties were measured with both rating scale and an objective task. IQ was obtained using the Wechsler Intelligence Scales (WISC–III/WAIS–III). Results:  Significant phenotypic (.2–.4) and familial (.3–.5) correlations were observed among ADHD, reading difficulties and IQ. Yet, 53%–72% of the overlapping familial influences between ADHD and reading difficulties were not shared with IQ. Conclusions:  Our finding that familial influences shared with general cognitive ability, although present, do not account for the majority of the overlapping familial influences on ADHD and reading difficulties extends previous findings from a population-based study to a clinically ascertained sample with combined type ADHD.

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.

Autism symptoms were compared in 821 ADHD probands, 1050 siblings and 149 controls. Shared familiality of autism symptoms and ADHD was calculated using DeFries-Fulker analysis. Autism symptoms were higher in probands than siblings or controls, and higher in male siblings than male controls. Autism symptoms were familial, partly shared with familiality of ADHD in males. Latent class analysis using SCQ-score yielded five classes; Class 1(31%) had few autism symptoms and low comorbidity; Classes 2–4 were intermediate; Class 5(7%) had high autism symptoms and comorbidity. Thus autism symptoms in ADHD represent a familial trait associated with increased neurodevelopmental and oppositional/conduct disorders.

Commentary: From noise to insight? Reaction time variability in ADHD and autism spectrum disorders – a commentary on Karalunas et al. (2014) / Jonna KUNTSI in Journal of Child Psychology and Psychiatry, 55-6 (June 2014)

But the persistence of this now widespread observation – with high RTV reported across many disorders – has led to investigators paying increasingly more attention to this initially uncool concept. Time is ripe, it seems, for listening to what the ‘noise’ in our reaction time (RT) data may tell us. It is against this background that the accompanying Annual Research Review by Karalunas and colleagues captures the current enthusiasm in trying to elucidate whether RTV reflects ‘a trans-diagnostic phenotype that is associated with shared risk for several disorders or with symptom domains that cut across several disorder categories’ or whether RTV could be ‘decomposed into distinct processes that differ among psychiatric conditions’. Focusing on two neurodevelopmental disorders, ADHD and autism spectrum disorders (ASD), Karalunas et al. performed two new meta-analyses and provide an additional review of the literature, which lead to helpful interim conclusions and open a discussion (which this Commentary preludes) on the next steps in our attempts to make sense of the RT ‘noise’.

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!).
