Neuropsychological Tasks

The literature on the neuropsychology of Attention Deficit Hyperactivity Disorder (ADHD) is plagued by inconsistent findings, which are usually attributed to a variety of extraneous variables. One of the most inadequately explored of these variables is the difference between ADHD children attending remedial and mainstream schools. This study aimed to investigate whether the performance of remedial and mainstream school ADHD boys differs on relevant neuropsychological tasks. The sample consisted of three groups of 8- to 12-year-old boys. Two of these groups consisted of children with ADHD: one from remedial schools and one from mainstream schools. The third group was made up of participants without ADHD, who attended mainstream schools. The performance of the remedial school learners on the Stroop, Lurian and cancellation tasks was investigated and compared to a mainstream school ADHD sample. The performance of the ADHD group as a whole was compared with that of a control group. No significant difference in performance was found between the two ADHD groups, except for the length of time taken to read words in the control condition of the Stroop. The control group out-performed the ADHD samples on the Stroop, Lurian and cancellation tasks. The findings suggest that mainstream and remedial ADHD boys do not differ in the severity of their executive deficits, but that boys with ADHD attending remedial schools may be more likely to have another learning disorder than their counterparts at mainstream schools.

Given that children with attention deficit hyperactivity disorder (ADHD) are more impulsive than peers, this study explored whether they are correspondingly more creative, and whether creativity declines when impulsivity is decreased through methylphenidate (Ritalin) therapy. A repeated-measures quasi-experimental design was used to compare the performance of 19 boys with previously diagnosed ADHD and 21 comparison boys aged 8 through 11 on two administrations of alternate forms of the Torrance Tests of Creative Thinking-Figural (nonverbal). Boys with ADHD received prescribed methylphenidate only for the first session. Overall, mean Torrance summary scores for comparison boys (mean = 115.1, SD = 16.1) were higher than for boys with ADHD (mean = 107.6, SD = 12.7). However, the difference between means was small (7%) and did not meet the 25% criterion for a clinically significant difference. No changes in performance over time (comparison group) or medication state (ADHD group) were observed. These data suggest that, when measured nonverbally, the creative thinking performance of boys with ADHD is not superior to that of peers who do not have ADHD. Regarding the effects of methylphenidate, prescribed therapy did not influence performance on this measure of creative thinking.

AbstractBackgroundVarious functional asymmetries detected by different neurophysiological and neuroimaging methods have been reported in the literature on the Attention Deficit Hyperactivity Disorder (ADHD), some of them pointing to the right hemisphere activity. In our attempt to discriminate the ADHD patients from normal subjects by hierarchical clustering of behavioural, psychological and event related potential (ERP) variables, the late P3 component of potentials from the right central region (C4) proved to be one of the most informative parameters (in preparation for publication). Here, we have studied the differences in ERPs between the left (C3) and right (C4) central leads and relation of this asymmetry to ADHD diagnosed using DSM.Methods20 typically developing (TD) boys and 19 boys diagnosed with ADHD according to DSM-IV-TR, aged 10-13 years, were examined by the Attentional Network Test (ANT), with simultaneous recording of the respective ERPs. The intergroup differences in the ERP amplitude parameters in the left (C3) and right (C4) central channels and in the difference in these parameters between the two channels (C3 minus C4) were accessed. These characteristics were compared to the subjects DSM scores and ANT performance.ResultsThe target-related potentials late characteristics from the C4 and C3 did not shown significant difference between the groups. The difference between ERPs of the C3 and C4 channels inside the interval of 40-290 ms after target onset was larger in the ADHD group than in control, mainly for incongruent target condition. This asymmetry and right late component were correlated with DSM scores, mainly to hyperactive and impulsive criteria.ConclusionIn ADHD patients, the results suggest ERP pattern of right-side functional predominance in the motor control, which correlates to DSM scores, mainly to hyperactive and impulsive criteria.

Abstract Objective Examination of retinal nerve, ganglion cell layer thickness and choroidal thickness in patients with Attention Deficit Hyperactivity Disorder by optical coherence tomography (OCT). Method : 30 individuals with Attention Deficit Hyperactivity Disorder and 30 healthy individuals compatible in terms of age and gender who applied to the Ophthalmology outpatient clinic for control were included in the study. The right and left eye data of the participants were used in statistical analysis. In addition to full ophthalmological examination (best corrected visual acuity, biomicroscopy, fundus examination), retinal nerve fiber layer (RNFL), ganglion cell layer (GCL) and macular choroidal thickness (MCT) were measured by OCT. RNFL, GCL and MCT measurements were compared between the groups. Conclusion There was no significant difference between the RNFL and GCL thickness values of the individuals in both groups (p > 0.05). When compared in terms of choroidal thickness, left eye su bfoveal choroidal thickness (p = 0.036, p < 0.05) and 2 mm temporal choroidal thickness were significantly higher in the ADHD group than in the control group (p = 0.034, p < 0.05). Discussion The aim of this study was to determine the clinical features of the eyes of children with ADHD. Cross-sectional studies with larger participation are needed to determine RNFL, GCL and choroidal changes.

BACKGROUND Children with attention-deficit/hyperactivity disorder (ADHD), a neurobehavioral disorder, display behaviors of inattention, hyperactivity, or impulsivity, which can affect their ability to learn and establish proper family and social relationships. Various tools are currently used by child and adolescent psychiatric clinics to diagnose, evaluate, and collect information and data. The tools allow professional physicians to assess if patients need further treatment, following a thorough and careful clinical diagnosis process. OBJECTIVE We aim to determine potential indicators extracted from a mobile electroencephalography (EEG) device (Mindset; NeuroSky) and an actigraph (MotionWatch 8; CamNtech) and to validate them for diagnosis of ADHD. The 3 indicators are (1) attention, measured by the EEG; (2) meditation, measured by the EEG; and (3) activity, measured by the actigraph. METHODS A total of 63 participants were recruited. The case group comprised 40 boys and 9 girls, while the control group comprised 5 boys and 9 girls. The groups were age matched. The test was divided into 3 stages—pretest, in-test, and posttest—with a testing duration of 20 minutes each. We used correlation analysis, repeated measures analysis of variance, and regression analysis to investigate which indicators can be used for ADHD diagnosis. RESULTS With the EEG indicators, the analysis results show a significant correlation of attention with both hit reaction time (RT) interstimulus interval (ISI) change (<i>r</i>=–0.368; <i>P</i>=.003) and hit standard error (SE) ISI change (<i>r</i>=–0.336; <i>P</i>=.007). This indicates that the higher the attention of the participants, the smaller both the hit RT change and the hit SE ISI change. With the actigraph indicator, confidence index (<i>r</i>=0.352; <i>P</i>=.005), omissions (<i>r</i>=0.322; <i>P</i>=.01), hit RT SE (<i>r</i>=0.393; <i>P</i>=.001), and variability (<i>r</i>=0.351; <i>P</i>=.005) were significant. This indicates that the higher the activity amounts, the higher the impulsive behavior of the participants and the more target omissions in the continuous performance test (CPT). The results show that the participants with ADHD present a significant difference in activity amounts (<i>P</i>&lt;0.001). The actigraph outperforms the EEG in screening ADHD. CONCLUSIONS When the participants with ADHD are stimulated under restricted conditions, they will present different amounts of activity than in unrestricted conditions due to participants’ inability to exercise control over their concentration. This finding could be a new electronic physiological biomarker of ADHD. An actigraph can be used to detect the amount of activity exhibited and to help physicians diagnose the disorder in order to develop more objective, rapid auxiliary diagnostic tools.

AbstractThe Lifetime Impairment Survey assessed impairment and symptoms of attention-deficit/hyperactivity disorder (ADHD) in children/adolescents from six European countries. Parents/caregivers of children/adolescents aged < 20 years with ADHD (ADHD group; n = 535) and without ADHD (control group; n = 424) participated in an online survey. History of ADHD diagnosis was self-reported. ADHD and control groups were compared using impairment and symptom scales; higher scores indicate greater impairment. Mean (SD) age at ADHD diagnosis was 7.0 (2.8) years, following consultation of 2.7 (2.6) doctors over 20.4 (23.9) months. Parents/caregivers (64%; 344/535) reported frustration with some aspect of the diagnostic procedure; 74% (222/298) were satisfied with their child's current medication. ADHD had a negative impact on children/adolescents in all aspects of life investigated. The ADHD group had a higher mean (SD) school impairment score (2.7 [0.7]) compared with the control group (2.1 [0.7]; P < 0.001) and were more likely to be in the bottom of their class (P < 0.001). These data provide insights into impairments associated with ADHD in childhood/adolescence, and identify areas for improvement in its management and treatment.

Many authors have suggested the association between Attention Deficit Hyperactivity Disorder (ADHD) and inflammation through various mechanisms among which increased serum cytokines.30 newly diagnosed ADHD children, aged 6-12and of both sexes were collected from outpatient clinic, Psychiatry Department, Al Zahraa University Hospital and a matched control group of 30 children. They were subjected to Clinical assessment, Whechsler Intelligence Scale for children (WISC), Conners' Parent Rating Scale-Revised & serum MMP-2, MMP-9, TNF-α levels were determined. There was statistical significant difference between patient and control groups regarding MMP-2 level (648.50 ± 81.94 vs 344.13 ± 32.02), MMP-9 level (143.00±16.98 vs 102.90 ± 4.13) & TNF-α level (345 ± 7.1.vs 202 ± 22.3). Hyperactive/impulsive subtype represented 16(53.3%), Inattentive subtype represented 6(20%), Combined subtype represented 8(26.7%) of the ADHD group. MMP-2, MMP-9, TNF-α levels were all higher among the Hyperactive/impulsive subtype, followed by thecombined subtype then the Inattentive subtype with high statistical significant difference. A high statistical significant difference was found in all subscales of Conners' scale among the 3 subtypes of ADHD. A positive correlation was found between TNF-α level and age, whereas, a negative correlation exists between MMP-2, MMP-9, TNF-α level and IQ. In addition, correlation was found between MMP-2, MMP-9 levels and cognitive problems, TNF-α level and inattention.Our study illustrates the co-occurrence of inflammatory process and ADHD, but further studies on larger sample are needed.

Abstract Background: Co-occurring psychiatric disorders in adults with Attention Deficit Hyperactivity Disorder (ADHD) and/or Autism Spectrum Disorder (ASD) contribute to the burden of the healthcare and possibly to the delay of diagnosis. Aim of the study was to clinically assess the prevalence and compare lifetime co-occurring psychopathology in a sample of newly diagnosed ADHD and/or ASD adults and discuss the diagnostic challenges they pose.Methods: The lifetime prevalence rates of ten of the most frequently co-occurring psychiatric diagnoses was registered in 336 adults of normal intelligence who underwent a thorough clinical evaluation for the diagnosis of ADHD and/or ASD for the first time in their lives. Four study groups were formed: the ADHD (n=151), the ASD (n=58), the ADHD+ASD (n=28) and the nonADHD/nonASD (NN) (n=88) group. Results: At least one co-occurring psychopathology was found in 72.8% of the ADHD group, in 50% of the ASD group, in 72.4% of the ADHD+ASD group and in 76.1% of the NN group (p=0.004). In all groups the most frequent psychiatric disorder was depressive disorder. The only significant difference regarding the patterns of psychiatric co-occurrence between the ADHD and the nonADHD groups (ASD and NN groups) was found for SUD (p=0.001). Also, the proportion of subjects with Bipolar Disorder was significantly greater in the NN group as compared to those with ASD (p=0.025). Conclusions: Our results support the high prevalence of co-occurring psychiatric disorders in adults with ADHD and/or ASD with the ASD group presenting the lowest rate. The most marked difference between the ADHD and the nonADHD groups was found for SUD. Moreover, our findings highlight the need for a thorough clinical assessment of all referred patients both in the presence and absence of ADHD and/or ASD.

The purpose of this cross-sectional study was to examine whether children with attention-deficit / hyperactivity disorder (ADHD) had a total caries experience that was equivalent to children without the disorder. Methods: The test sample included children ages 6 to 10 years old diagnosed with ADHD by physicians at Duke University Medical Center. The control group also included healthy children 6 to 10 years old without the diagnosis of ADHD.A visual dental exam for caries was performed and a sample of whole, unstimulated saliva was collected. The parent / guardian of each participant completed a health/medication history and a questionnaire concerning the child's oral health and habits, daily routine, and demographic information. Results: Wilcoxon and chi-square tests showed that children with ADHD have significantly more enamel caries in the primary and permanent dentitions and a significantly higher prevalence of total caries experience when compared to controls. There was no significant difference in whole saliva production between the ADHD children and the controls. Conclusions: Dentists should be aware that children with ADHD are at higher risk for caries.

Connectivity Strength

Objective: This study aimed to investigate differences in brain networks between healthy children and children with attention deficit hyperactivity disorder (ADHD) during an attention test. Method: To fulfill this, we constructed weighted directed graphs based on Electroencephalography (EEG) signals of 61 children with ADHD and 60 healthy children with the same age. Nodes of graphs were 19 EEG electrodes, and the edges were phase transfer entropy (PTE) between each pair of electrodes. PTE is a measure for directed connectivity that determines the effective relationship between signals in linear and nonlinear coupling. Connectivity graphs of each sample were constructed using PTE in the five frequency bands as follows: delta, theta, alpha, beta, and gamma. To investigate the differences in connectivity strength of each node after the sparsification process with two values (0.5 and 0.25), the permutation statistical test was used with the statistical significance level of p<0.01. Results: The results indicate stronger inter-regional connectivity in the prefrontal brain regions of the control group compared to the ADHD group. However, the strength of inter-regional connectivity in the central regions of the ADHD group was higher. A comparison of the prefrontal regions between the two groups revealed that the areas of the Fp1 electrode (left prefrontal) in healthy individuals play stronger transmission roles. Conclusion: Our research can provide new insights into the strength and direction of connectivity in ADHD and healthy individuals during an attention task.

Background: Individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) are reported to manifest visual problems (including ophthalmological and color perception problems, particularly for blue-yellow stimuli), but findings are inconsistent. Accordingly, this study investigated visual function and color perception in adolescents with ADHD using VEP. Method: Participants were 31 adolescents (aged 13-18); 16 with a confirmed diagnosis of ADHD, and 15 healthy peers, matched for age, gender, and IQ. All underwent ophthalmological exam, color vision testing (Mollon-Reffin Minimalist Colour Vision Test), as well as electrophysiological testing (color Visual Evoked Potentials; cVEP) which measured the latency and amplitude of the neural P1 response to chromatic stimuli (Blue-Yellow, Red-Green). Result: No group differences were found in clinical measure of color perception or opthalmological exam. However, significantly larger P1 amplitude was found for blue and yellow stimuli, but not red/green stimuli, in the ADHD group compared to controls. Discussion: Larger amplitude in the P1 component for blue-yellow in ADHD group compared to control group may account for no difference in colour perception task. Perhaps activating more resources in early sensory processing (P1) compensated for any underlying problems including compromised retinal input of s-cones due to hypo-dopaminergic tone.
