An operational definition of mind wandering is when one has thoughts unrelated to the current task(s) (Smallwood & Schooler, 2015). Mind blanking can be thought of as a subtype of mind wandering where there is an inability to report the content of these task-unrelated thoughts. Van den Driessche et al. (2017) found that children and young adults with more Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms report more mind blanking than those with fewer ADHD symptoms and that non-medicated children with ADHD reported less mind wandering and more mind blanking than medicated children with ADHD. Van den Driessche et al. speculated that medication facilitated executive control and that executive resources support mind wandering (and on-task thought). These findings also bear on the theoretical debate on the role of executive functions in conscious experience. Some argue that executive functions support mind wandering (Levinson et al., 2012; Smallwood, 2010), while others argue and that mind wandering situationally results from a lack (or failure) of executive control (McVay & Kane, 2010; Meier, 2019). In this study, with a young adult sample, I tested the association between ADHD symptomology and conscious experience and if executive resources moderate the proportion of reporting mind blanking and mind wandering. The current study found evidence for Van den Driessche et al.’s finding of a positive and significant association between mind blanking and ADHD symptomology. The current study was also broadly consistent with Van den Driessche et al.’s finding of an ADHD-related trade-off involving mind blanking, but importantly differs from Van den Driessche et al. in that mind wandering was not involved in this trade-off. The current study did not find an association between working memory capacity and mind wandering. Thus, I found no evidence for executive resources supporting mind wandering, consistent with previous studies (McVay & Kane, 2009, 2012a, 2012b; Meier, 2019; Robison & Unsworth, 2018; Unsworth & McMillan, 2013, 2014).

Van den Driessche et al. (2017) found that children and young adults with more Attention Deficit Hyperactivity Disorder (ADHD) symptoms report more mind blanking than those with fewer ADHD symptoms and that non-medicated children with ADHD reported less mind wandering and more mind blanking than medicated children with ADHD. Van den Driessche et al. speculated that medication facilitated executive control and that executive resources support mind wandering (and on-task thought). Besides describing the conscious experience of those with ADHD symptomology, these findings bear on the theoretical debate of executive functions’ role in conscious experience. Some argue that executive functions support mind wandering (Levinson, Smallwood, & Davidson, 2012; Smallwood, 2010, 2013), while others argue that mind wandering situationally results from a lack (or failure) of executive control (McVay & Kane, 2010; Meier, 2019). Here, we conducted a study like Van den Driessche et al.’s study with young adults (Experiment 2, 2017) and tested the associations between ADHD symptomology and conscious experience. Rather than speculating about the effects of medication, we directly measured executive functioning (via complex span tasks). Like Van den Driessche et al., we observed a positive association between mind blanking and ADHD, but we detected no evidence supporting the claim that executive functions support mind wandering. We also assessed the relative associations between task performance metrics and reports of mind blanking and mind wandering. We did not detect differential performance associations between those thought reports.

During one year (september 2013 � september 2014), 50 children from the residential institution for children SOS Satele Copiilor Bucharest, where included in our research. The children were distributed in two groups: Group A which consisted of 25 children (12 girls, 13 boys) who were not diagnosed with attention deficit hyperactivity disorder (ADHD) and Group B which consisted of 25 children (14 boys, 11 girls) who were diagnosed with ADHD. Initially, the two groups were subjected at a psycho-diagnostic battery of tests, one of them being the Evaluating the Health State of children with ADHD questionnaire elaborated by us, particularly for this research, with the purpose of highlighting the direct link between the children health state and their ADHD symptoms. This study sought to determine the concentration of copper in urine samples from a group of children with ADHD and a group of normal children, to highlight the role of copper in the development of ADHD symptoms. Levels of copper concentration in urine samples from the two groups were processed by Student�s t-Test. Statistical analysis showed that the arithmetic averages of copper concentration in urine samples, of the two groups do not differ significantly, so copper may be causing ADHD symptoms occur. The copper content in urine samples has been determined using atomic absorption spectrometry with graphite furnace.

Resent research has shown that electroencephalography (EEG) theta/beta ratio (TBR) in cases with attention deficit hyperactivity disorder (ADHD) has thus far been reported lower than that in healthy individuals. Accordingly, utilizing EEG-TBR as a biomarker to diagnose ADHD has been called into question. Besides, employing known protocol to reduce EEG-TBR in the vertex (Cz) channel to treat ADHD via neurofeedback (NFB) has been doubted. The present study was to propose a new NFB treatment protocol to manage ADHD using EEG signals from 30 healthy controls and 30 children with ADHD through an attention-based task and to calculate relative power in their different frequency bands. Then, the most significant distinguishing features of EEG signals from both groups were determined via a genetic algorithm (GA). The results revealed that EEG-TBR values in children with ADHD were lower compared with those in healthy peers; however, such a difference was not statistically significant. Likewise, inhibiting alpha band activity and enhancing delta one in F7 or T5 channels was proposed as a new NFB treatment protocol for ADHD. No significant increase in EEG-TBR in the Cz channel among children with ADHD casts doubt on the effectiveness of using EEG-TBR inhibitory protocols in the Cz channel. Consequently, it was proposed to apply the new protocol along with reinforced beta-band activity to treat or reduce ADHD symptoms.

Objective: Children and adults with ADHD often report sleep disturbances that may form part of the etiology and/or symptomatology of ADHD. We review the evidence for sleep changes in children with ADHD. Methods: Systematic review with narrative synthesis assessing sleep and circadian function in children aged 5 to 13 years old with a diagnosis of ADHD. Results: 148 studies were included for review, incorporating data from 42,353 children. We found that sleep disturbances in ADHD are common and that they may worsen behavioral outcomes; moreover, sleep interventions may improve ADHD symptoms, and pharmacotherapy for ADHD may impact sleep. Conclusion: Sleep disturbance may represent a clinically important feature of ADHD in children, which might be therapeutically targeted in a useful way. There are a number of important gaps in the literature. We set out a manifesto for future research in the area of sleep, circadian rhythms, and ADHD.

Objective: The purpose of this study was to investigate the overlap between executive functions and temperament as measured by two questionnaires and to examine characteristic profiles in children with ADHD and clinical controls. Method: Parents of 111 clinically referred children, half of whom were diagnosed with ADHD and half with other or no diagnoses, completed the Behavior Rating Inventory of Executive Function (BRIEF) and the Cloninger Junior Temperament and Character Inventory (JTCI). Results: Factor analysis of both instruments resulted in three common factors representing aspects of (1) cognitive regulation, (2) behavioral regulation, and (3) anxious/rigid tendencies. Factor (4) represented strengths and positive resources and loaded on JTCI scales only. Both instruments discriminated significantly between ADHD and non-ADHD children. Conduct disorder/oppositional defiant disorder (CD/ODD) but not ADHD accounted for problems in BRIEF Emotional Control and Self-Monitor and JTCI low Cooperativeness. Conclusion: The two instruments only partially overlap and may complement each other.

Objective. This study evaluated the effects on behavior and sleep of methylphenidate (MPH) administered at 4 PM to children with attention-deficit hyperactivity disorder (ADHD). Methodology. Twelve children admitted to a child psychiatric inpatient service with ADHD participated in a double-blind, crossover study in which they received a 4 PM dose of either 15 mg of MPH, 10 mg of MPH, or a placebo in random order for 12 consecutive days. Ratings of behavior, including ADHD symptoms, pertaining to the period from dose administration until sleep onset, were supplied nightly by hospital staff. Sleep latency and sleep adequacy were also assessed for each night. Results. MPH resulted in markedly improved behavioral control compared with placebo; there was no difference between 15-mg and 10-mg MPH doses. MPH did not alter sleep latencies observed with the placebo. Children were more often rated as less tired on awakening after nights that they received 10 mg of MPH compared with 15 mg of MPH and the placebo. Weight loss was apparent among 83% of the patients, but dinner intake did not vary with third-dose condition. Conclusions. Morning and noon administration of stimulants to children with ADHD is a near-universal practice, but many clinicians avoid a third, late-afternoon administration for fear of inducing insomnia. This study's findings show that children with ADHD derive substantial symptom reduction from MPH administered in late afternoon, with no untoward effects on sleep. Therefore, three-times-a-day dosing should be considered for those children exhibiting ADHD symptoms in the evening. Adverse effects on sleep latency were not apparent in the sample overall. Nonetheless, monitoring for possible aggravation of sleep problems and weight loss remains sound treatment practice.

Objective: The study examined how the interplay between maternal ADHD symptoms and maternal inhibitory control and child ADHD is related to parenting behaviors. Method: The sample included 141 mothers and their 8- to 12-year-old children, 61 children with ADHD and 80 without. Parenting was measured using self-reports (i.e., overreactive and lax parenting) and observation (i.e., negative and supportive parenting). Maternal inhibitory control was measured using a neurocognitive task. Hierarchical multiple regressions were conducted to predict parenting, controlling for child sex, conduct behaviors, and parenting distress. Results: Interactions between maternal ADHD symptoms and maternal inhibitory control suggested that hyperactive–impulsive symptoms were linked to parenting negativity only when inhibitory control was low, and maternal inattention symptoms were related to lax parenting only when maternal inhibitory control was high or when children did not have ADHD. Conclusion: Results indicate the importance of maternal regulation processes in the mechanisms linking maternal ADHD with parenting.
