Meta Analyses

Starting from the consolidated relationship between sleep and cognition, we reviewed the available literature on the association between Attention Deficit-Hyperactivity Disorder (ADHD) and sleep. This review analyzes the macrostructural and microstructural sleep features, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria (PRISMA). We included the polysomnographic studies published in the last 15 years. The results of macrostructural parameters are mixed. Almost half of the 18 selected investigations did not find differences between sleep architecture of children with ADHD and controls. Five studies observed that children with ADHD show a longer Rapid Eye Movement (REM) sleep duration than controls. Eight studies included microstructural measures. Remarkable alterations in sleep microstructure of ADHD are related to slow wave activity (SWA) and theta oscillations, respectively, during Non-REM (NREM) and REM sleep. Specifically, some studies found higher SWA in the ADHD group than controls. Similarly, higher theta activity appears to be detrimental for memory performance and inhibitory control in ADHD. These patterns could be interpreted as a maturational delay in ADHD. Also, the increased amount of these activities would be consistent with the hypothesis that the poor sleep could imply a chronic sleep deprivation in children with ADHD, which in turn could affect their cognitive functioning.

AbstractTheories of attention deficit/hyperactivity disorder (ADHD) increasingly highlight the role of neuropsychological impairment in ADHD; however, a consistent and identifiable pattern of performance on tests is not well established. The National Institutes of Health (NIH) Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research (EXAMINER) battery provides measures of common variance across multiple executive function tests within specific domains and was used to characterize which executive functions are most affected in children with ADHD. Thirty-two children (24 male), ages 8–15 years (M = 12.02; SD = 2.29), diagnosed with ADHD and no comorbid disorder completed the NIH EXAMINER battery. Sixty age and gender matched healthy controls were chosen from a database of participants enrolled in the NIH EXAMINER multi-site study. Children with ADHD performed worse on the working memory score compared with the controls. No differences were found on the cognitive control or fluency scores. For children with ADHD, poorer working memory performance predicted parent report of child learning problems. Cognitive control and fluency scores did not predict learning problems. In summary, working memory emerges as a primary impairment in children with ADHD who have no comorbid disorders. Furthermore, working memory weaknesses may underlie the academic problems often seen in children with ADHD. (JINS, 2013, 19, 1–11)

Sleep Microstructure

The high rate of occurrence of sleep disturbances in children with attention-deficit/hyperactivity disorder (ADHD) prompted the idea that structural and neurotransmitter changes might give rise to specific sleep pattern abnormalities. The aim of this study was to evaluate the microstructure of sleep in children with ADHD who had no polysomnographically diagnosed sleep disorder, had never been treated for ADHD, and were free from any psychiatric comorbidity. Participants were 14 patients with ADHD (12 boys and 2 girls aged 7-12 years, mean age 9.6±1.6). ADHD was diagnosed according to DSM-IV criteria (Diagnostic and statistical manual of mental disorders). Psychiatric comorbidities were ruled out by detailed psychiatric examination. The patients underwent two consecutive overnight video-polysomnographic (PSG) recordings, with the sleep microstructure (cyclic alternating pattern – CAP) scoring during the second night. The data were compared with age- and sex-matched controls. Sleep microstructure analysis using CAP revealed no significant differences between the ADHD group and the controls in any of the parameters under study. In conclusions, no ADHD-specific alterations were found in the sleep microstructure.

Background Attention-deficit/hyperactivity disorder (ADHD) is a neurobehavioral abnormality that commonly occurs among children. Sleep disorders are comorbid with ADHD. Sleep disorders in Indonesian children with ADHD have not been widely studied.Objective To understand the proportion and factors that influence sleep disorders in children with ADHD. Methods This cross-sectional study involved 54 children aged 3-14 years who had been diagnosed with ADHD by a pediatric growth and development consultant using DSM-5 criteria. The subjects were consecutively selected from March to August 2017 at the Child Development Polyclinic, Dr. Sardjito Hospital, Yogyakarta. Sleep data were collected using the Sleep Disturbances Scale for Children (SDSC) and the Children’s Sleep Hygiene Scale (CSHS).Results Of the 54 children with ADHD (46 males and 8 females), 35 (64.8%) experienced sleep disorders. The majority (26 subjects, 48.1%) had the disorder of initiating and maintaining sleep. Children with the combined (inattention and hyperactive-impulsive) type of ADHD experienced significantly greater sleep disturbance compared to the inattention type or hyperactive-impulsive type (OR=3.750; 95% CI 1.133 to 12.41; P=0.027). Poor sleep hygiene was also significantly associated with more severe sleep disorders (r=-0.383, P=0.004).Conclusion The proportion of sleep disorder in children with ADHD is relatively high, with the majority having a disorder of initiating and maintaining sleep. Children with combined type ADHD experience a higher amount of sleep disorder than those with either the inattention or hyperactive-impulsive types of ADHD. Children with poor sleep hygiene have significantly more severe sleep disorders.

Introduction/Objective. The aim of this study was to coIntroduction/Objective. The aim of this study was to compare kinematic features and graphic rules of writing between children with attention deficit/hyperactivity disorder (ADHD) (with and without medical treatment) and typically developed children (TDC). Methods. In total, 55 children (26 with ADHD/ten subjects were on methylphenidate treatment and 29 TDC) completed a writing task on a digitizing board (in three repetitions; using non-inking stylus) which included a semicircle tracing, triangle, and letter copying. Kinematic features of movements in all tasks and graphic rules during a semicircle tracing were analyzed. Graphic rules were observed as expected movements (selecting the starting point and direction of tracing). Results. The values of kinematic parameter jerk were significantly larger in TDC group compared to all ADHD subjects (regardless of treatment) and increased constantly with semicircle task progression and repetition in both groups. Children with ADHD without methylphenidate treatment used overall slower movements compared to TDC. The tracing of children with ADHD taking methylphenidate was more automated (with less change in movement velocity and acceleration) compared to TDC. In ADHD group only, those with treatment traced faster and more automated compared to those without treatment. The majority of subjects used expected movements in semicircle tracing and this percentage increased with the task repetition (without difference between ADHD and TDC). Conclusion. Both children with ADHD and TDC used similar approach in the tracing task and were compliant with graphic rules. Methylphenidate treatment may positively influence writing kinematics in children with ADHD. Task repetition also influences writing.

Objective: To measure levels of vitamin A (VA) and vitamin D (VD) and the symptomatic association of their co-deficiencies on attention deficit hyperactivity disorder (ADHD) in Chinese children (6–9 years).Methods: Eighty-two children (69 boys and 13 girls; mean age = 7.1 ± 0.9 years at the time of the diagnosis) with ADHD were recruited as ADHD group. A total of 106 healthy children were recruited as the healthy control (HC) group. Serum levels of retinol and 25-hydroxyvitamin D (25(OH)D) of all children were evaluated using high-performance liquid chromatography (HPLC) and HPLC-tandem mass spectrometry. The Swanson, Nolan, and Pelham IV Rating Scale (SNAP-IV) was employed to assess the clinical symptoms of ADHD.Results: Children suffering from ADHD had significantly reduced serum levels of retinol and 25(OH)D compared with those of HCs, and the prevalence of VA deficiency and VD deficiency were higher in children suffering from ADHD. Serum concentrations of 25(OH)D and retinol were linked closely with the presence or absence of ADHD after adjustment for age, body mass index, season of blood sampling, and sun exposure. Serum concentrations of 25(OH)D and retinol showed a negative correlation with the total scores of SNAP-IV. Children with ADHD as well as VA and VD co-deficiency had increased SNAP-IV total scores and ADHD inattention subscale scores.Conclusion: VA deficiency and VD deficiency in children with ADHD were increased in comparison with that in HCs. VA and VD co-deficiency associated with ADHD symptom severity. Attention should be paid to regular testing of VA levels and VD levels. However, the mechanism of VA and VD in ADHD needs to be further studied. Interventional studies on VA and VD supplementation are recommended to further verify the relationship between VA and VD co-deficiency and ADHD.

AbstractShifts in covert visual attention were compared in children with and without Attention Deficit Hyperactivity Disorder (ADHD) to determine if children with ADHD have developmental immaturities in covert attention, relative to their non-ADHD peers. Children were told to orient attention to a central fixation point and were then cued, by both central and peripheral cues, to direct their attention to either the left or right peripheral fields. Following variable time intervals, the target appeared and reaction times and errors were recorded. Although performance of all subjects showed faciliation when attention was directed by valid cues and inhibition when attention was directed by invalid cues, the performance of children with ADHD was far more disrupted when their attention was misled by invalid cues, especially at longer intervals. This inconsistency was reflected in significantly higher error rates in the ADHD group. They also showed a pattern of attentional “waxing and waning” in performance over longer time intervals that has been previously found in auditory attention switching over time within trials in children with ADHD. Overall, results are inconsistent with developmentally immature covert attention skills in ADHD. Findings are discussed in terms of the concept of global “developmental immaturity” in the attention skills of children with ADHD.

ABSTRACT Purpose: to compare aspects of memory, learning and oral comprehension between children with Attention Deficit Hyperactivity Disorder (ADHD) and children with Anxiety Disorder (AD). Methods: thirty-two children (7-10 years) were divided into: G1 - children diagnosed with ADHD, and G2 - children diagnosed with AD. The children were not under drug treatment. The tests applied assessed working memory (phonological loop and visuospatial sketch), learning, episodic memory and oral comprehension. Results: both groups showed changes in working memory for visuospatial sketch and phonological loop (worse performance in pseudowords in the ADHD group and digit-reversed order for children with AD), and in oral comprehension. Group comparison showed a statistically significant difference regarding the most complex level of the oral comprehension test and the repetition of nonwords with three syllables. Both groups showed a suitable performance in learning ability, however, the group of children with ADHD suffered from backward interference, with no memory consolidation, showing low episodic memory performance. Conclusion: children with ADHD and anxiety disorder showed various altered cognitive skills, although group comparison revealed that children with ADHD exhibited worse cognitive performance.

Objective: Studies prior to 1999 reported prevalent sleep disturbances in children diagnosed with attention deficit hyperactivity disorder (ADHD). However, these reports were largely inconclusive and inconsistent in their findings, hence the current review based on studies published thereafter. Method: An online research of the National Library of Medicine and the Cochrane Library was conducted using the terms ‘attention deficit hyperactivity disorder’, ‘sleep’, ‘human’, and ‘English language’. Results: Sixteen articles met the search criteria with 10 reporting objective measures of sleep characteristics (i.e. polysomnography, actigraphy, and/or video recording). These studies confirm an increase of rapid eye movement (REM) sleep latency and a proportional decrease of REM sleep in children diagnosed with ADHD. Stimulant treatment appears to have little effect on sleep quality while parent's reports of poor sleep in their ADHD-diagnosed offspring was largely inconsistent with the objective measures. Conclusions: The review demonstrated a link between disturbances in sleep architecture and ADHD. Whether this is of an intrinsic or extrinsic cause remains debateable, as both behavioural (parental reporting) and physiological (objective differences in sleep architecture) factors are indicated. The effect of stimulant medication on sleep also requires further research, as current evidence is limited by study design.

Galectin 3

Objective Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with underlying pathogenesis and etiological factors not fully understood. We assumed that galectin-3, which is also linked with inflammatory responses, may play an important role in the ethiopathogenesis of ADHD. In this study, we aimed to investigate whether serum galectin-3 levels are related to ADHD in childhood.Methods The current study consisted of 35 treatment-naive children with ADHD and 35 control subjects. The severities of ADHD and conduct disorder symptoms were assessed via parent- and teacher-rated questionnaires. The severity of anxiety and depression symptoms of the children were determined by the self-report scale. Venous blood samples were collected and serum galectin-3 levels were measured.Results The ADHD group had significantly higher serum Galectin-3 levels than the control group. To control confounding factors, including age, sex, and BMI percentile, one-way analysis of covariance (ANCOVA) test was also performed. Analyses revealed a significantly higher serum log- Galectin-3 levels in children with ADHD compared to controls. No association was found between the mean serum galectin-3 levels and sociodemographic characteristics and clinical test scores, except the oppositional defiant behavior scores.Conclusion Our research supports the hypothesis that serum levels of galectin-3 might be related to ADHD.

Objective: The present study aimed to examine the association between attention-deficit–hyperactivity disorder (ADHD) and maternal psychological distress, parenting style and perceived family support, and the child's interaction with parents and behavioural problems at home in Taiwan. Methods: The sample included 375 medicated pediatric patients with DSM-IV ADHD, and 750 school controls selected based on the age and gender structures of the ADHD group. Mothers reported on the Chinese Health Questionnaire, the Chinese versions of the Parental Bonding Instrument, the Family Adaptation, Partnership, Growth, Affection, and Resolve, and the Home Behaviours of the Social Adjustment Inventory for Children and Adolescents. Results: Mothers of children with ADHD reported greater psychological distress and perceived less support from their families than did mothers of controls. Moreover, mothers of children with ADHD were less affectionate and more overprotective and controlling toward their children than were mothers of controls. This difference was more apparent in boys than in girls. Children with ADHD were less likely to interact with their parents, yet demonstrated more severe behavioural problems at home. Conclusions: Although the Taiwanese children with ADHD were under treatment with methylphenidate, they and their families still encountered a variety of difficulties in interaction, support, and communication with each other. Therefore, the parental approach should be integrated into the medication treatment for ADHD in Taiwan.
