ABSTRACT Objective: to analyze possible negative effects of Attention Deficit Hyperactivity Disorder (ADHD) on the success of bariatric surgery. Methods: we evaluated forty patients undergoing bariatric surgery and with regular post-operative follow-up of at least one year. To all, we applied the questionnaire advocated in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV) of the American Psychiatric Association for ADHD, as well as analyzed their postoperative data. Results: fifteen (38%) patients presented a positive questionnaire for ADHD. Patients with ADHD presented higher BMI than patients without the disorder (45.8 vs. 40.9 kg/m2, p=0.017), and the difference remained in all postoperative stages. There was no statistically significant difference in surgery success (33.3% x 66.7%, p=0.505) or in BMI reduction (30.71% x 31.88%, p=0.671) one year after the procedure. Conclusion: ADHD patients have a higher BMI. However, the presence of ADHD does not influence the success of bariatric surgery and the reduction of BMI.

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.

AbstractA system based on objective data was developed in the diagnosis and follow-up of attention-deficit hyperactivity disorder (ADHD) in this study. First of all, an electronic circuit, with a two-channel instrumentation amplifier designed to detect eye movements in the horizontal and vertical directions via surface electrodes, was developed to obtain the electrooculogram (EOG) signals. In order to provide a controlled analysis of eye movements during the reception of the signal, an attention test with visual stimulus software was developed. Eight patients with ADHD and eight healthy subjects were asked to monitor the stimulus images on the screen in the reference directions of the test system while recording EOG signals. According to the results of the t-test, no significant difference was found (p=0.11) between the healthy group and the reference movement information, whereas a significant difference was found between patients and the reference motion information (p=0.049). According to these results, it was seen that the number of eye movements of healthy individuals was statistically significant. In addition, they were inconsistent with the reference movement information. The level of significance was found to be low in patients. In this study, a new method is presented to test and diagnose individuals who were attention deficit.

Purpose; The aim of this study was to comparison of the effectiveness of two methods of motivational manipulation and neurofeedback on sensitivity to reward, delay discounting and impulsivity in children with attention deficit / hyperactivity disorder. Methods; The present study was an experimental study with pre-test, post-test, follow-up and control group. The study population consisted of children aged 7 to 12 years with ADHD. Available sampling method was used for sampling in this study. Sample size was selected based on the purpose and method of research (in experimental research, the sample size of at least 30 people in each group is recommended) 90 people. In this study, neurofeedback and motivational manipulation were performed on the intervention group as an intervention, each session was performed for 12 sessions and each session was performed for 45 minutes. Balloon risk test and delay discounting test were used to collect data in pre-test, post-test and follow-up stages and the data were analyzed using MANCOVA statistical method in SPSS-23. Results; By controlling the effects of pretest on posttest, the difference between the groups in the posttest was statistically significant between the variables of impulsivity and delay at the level of P <0.01 and between the variables of reward sensitivity at the level of P <0.05. The results also showed that neurofeedback method (M = 4.66) had a greater effect on reward processing than motivational manipulation method (M = 2.31) compared to the control group, which was significant at the level of P <0.01. But the difference between the mean of motivational manipulation (M = 2.31) in comparison with the control group was not significant. Conclusion; Voluntary activation of dopaminergic regions of the brain by neurofeedback and motivational manipulation leads to endogenous dopamine control in these structures, leading to successful regulation or inhibitory control and reduced cravings, which reduces impulsivity, delay discounting, and sensitivity to reward.

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.

Background and Objective. Dopamine dysfunction is known to be associated with attention deficit hyperactivity disorder (ADHD). Dopamine D4 receptor gene (DRD4) is one of the important genes in this pathway. This study intended to investigate the variable number of tandem repeats (VNTR) in exon 3 of the DRD4 gene in Iranian children and adolescents. Materials and Methods. In this study, 130 children with ADHD, aged 6–14 years, and 130 healthy children, within the same age range, were enrolled. All children were selected from northwest of Iran which have Caucasian ethnic background and are of a Turkic ethnic group. VNTR polymorphisms of the DRD4 gene were evaluated by PCR using exon 3-specific primers followed by agarose gel electrophoresis. Findings. The Hardy-Weinberg principle and Chi-square test showed a significant difference in 4-repetition (4R) alleles between the ADHD (76.2%) and control (53.8%) groups (p=0.004; X2=17.39; df=5). The least percentage of repetition alleles in both groups was 2R. Conclusion. There is a significant correlation between the 4R alleles of DRD4 and ADHD in the northwest of Iran.
