Does EEG-neurofeedback improve neurocognitive functioning in children with attention-deficit/hyperactivity disorder? A systematic review and a double-blind placebo-controlled study / Madelon A. VOLLEBREGT in Journal of Child Psychology and Psychiatry, 55-5 (May 2014)

For this reason, a double blind, randomized, placebo-controlled study was designed to assess the effects of EEG-neurofeedback on neurocognitive functioning in children with ADHD, and a systematic review on this topic was performed. Methods Forty-one children (8–15 years) with a DSM-IV-TR diagnosis of ADHD were randomly allocated to EEG-neurofeedback or placebo-neurofeedback treatment for 30 sessions, twice a week. Children were stratified by age, electrophysiological state of arousal, and medication use. Neurocognitive tests of attention, executive functioning, working memory, and time processing were administered before and after treatment. Researchers, teachers, children and their parents, with the exception of the neurofeedback-therapist, were all blind to treatment assignment. Outcome measures were the changes in neurocognitive performance before and after treatment. Clinical trial registration: www.clinicaltrials.gov: NCT00723684. Results No significant treatment effect on any of the neurocognitive variables was found. A systematic review of the current literature also did not find any systematic beneficial effect of EEG-neurofeedback on neurocognitive functioning. Conclusion Overall, the existing literature and this study fail to support any benefit of neurofeedback on neurocognitive functioning in ADHD, possibly due to small sample sizes and other study limitations.

Grasping Motor Impairments in Autism: Not Action Planning but Movement Execution is Deficient / Astrid M.B. STOIT in Journal of Autism and Developmental Disorders, 43-12 (December 2013)

Thirty-one children and adolescents with ASD and twenty-nine matched controls participated in a two-choice reach-to-grasp paradigm wherein participants received cueing information indicating either the object location or the required manner of grasping. A similar advantage for location cueing over grip cueing was found in both groups. Both accuracy and reaction times of the ASD group were indistinguishable from the control group. In contrast, movement times of the ASD group were significantly delayed in comparison with controls. These findings suggest that movement execution rather than action planning is deficient in ASD, and that deficits in action chaining derive from impairments in internal action models supporting action execution.

Internal model deficits impair joint action in children and adolescents with autism spectrum disorders / Astrid M.B. STOIT in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)

The present study investigated the hypothesis that impaired social interaction in ASD reflects a deficit to internally model the behavior of a co-actor. Children and adolescents with ASD and matched controls performed a computerized bar-balancing task in a solo condition (S), and together with another individual in two joint action conditions (J2 and J4) in which they used either two or four hands to control the bar lift. Consistent with predictions derived from the ‘internal modelling hypothesis’, results from the J2 task indicated that ASD dyads were impaired in predicting the occurrence of their partner's response and failed to coordinate their actions in time. Furthermore, results from the J4 task showed that ASD participants used an adaptive strategy to disambiguate their responses from their partner's by regulating opposite sides of the bar during lifting. These findings provide empirical support of theories positing the existence of an internal modelling deficit in ASD. In addition, our findings suggest that impaired social reciprocal behavior and joint cooperative play exhibited by individuals with ASD may reflect behavioral adaptations to evade conflicting or ambiguous information in social settings.

The dopamine receptor D4 7-repeat allele and prenatal smoking in ADHD-affected children and their unaffected siblings: no gene–environment interaction / Marieke E. ALTINK in Journal of Child Psychology and Psychiatry, 49-10 (October 2008)

The purpose of this study is to examine the gene by environment (G×E) interaction of the DRD4 7-repeat allele and smoking during pregnancy on ADHD and oppositional behavior in families from the International Multicenter ADHD Genetics project; and further, to test the hypothesis that the direction of effect of the DRD4 7-repeat allele differs between ADHD affected and unaffected children. Methods: Linear mixed models were used to assess main and interactive effects of the DRD4 7-repeat allele and smoking during pregnancy in 539 ADHD-affected children and their 407 unaffected siblings, aged 6–17 years. Results: There was some evidence pointing to differential effects of the DRD4 7-repeat allele on ADHD and oppositional symptoms in the affected (fewer symptoms) and unaffected children (increasing ADHD symptoms of teacher ratings). Affected children were more often exposed to prenatal smoking than unaffected children. There were limited main effects of prenatal smoking on severity of symptoms. Given the number of tests performed, no indication was found for G×E interactions. Conclusion: Despite the large sample size, no G×E interactions were found. The impact of the DRD4 7-repeat allele might differ, depending on affected status and rater. This finding is discussed in terms of differences in the activity of the dopaminergic system and of different genes involved in rater-specific behaviors.

Working memory training in young children with ADHD: a randomized placebo-controlled trial / Martine VAN DONGEN-BOOMSMA in Journal of Child Psychology and Psychiatry, 55-8 (August 2014)

To this end, a triple-blind, randomized, placebo-controlled study was designed to assess the efficacy of Cogmed Working Memory Training (CWMT) in young children with ADHD. Methods Fifty-one children (5–7 years) with a DSM-IV-TR diagnosis of ADHD (without current psychotropic medication) were randomly assigned to the active (adaptive) or placebo (nonadaptive) training condition for 25 sessions during 5 weeks. The compliance criterion (20 sessions) was met for 47 children. The primary outcome measure concerned the core behavioural symptoms of ADHD, measured with the ADHD Rating Scale IV (ADHD-RS). Secondary outcome measures were neurocognitive functioning, daily executive functioning, and global clinical functioning. The influence of the increase in difficulty level (Index-Improvement) for the treatment group was also analysed. Clinical trial registration information – ‘Working Memory Training in Young ADHD Children’; www.clinicaltrials.gov; NCT00819611. Results A significant improvement in favour of the active condition was found on a verbal working memory task (p = .041; adapted Digit Span WISC-III, backward condition). However, it did not survive correction for multiple testing. No significant treatment effect on any of the primary or other secondary outcome measurements was found. The Index-Improvement significantly contributed to ADHD-RS and the Behavior Rating Inventory of Executive Function, both rated by the teacher, but revealed no significant group difference. Conclusions This study failed to find robust evidence for benefits of CMWT over the placebo training on behavioural symptoms, neurocognitive, daily executive, and global clinical functioning in young children with ADHD.
