Background. Children with attention deficit hyperactivity disorder (ADHD) may suffer from working memory deficits, which can adversely affect their academic performance. Neurofeedback training may enhance working memory and provide a solution to this problem. Aim. To investigate the effect of frequency-neurofeedback on working memory in children with ADHD and to check if the effect is long-lasting. Method. Forty-eight children with ADHD (aged 6-12 years) were randomly assigned either to a neurofeedback with training parameters chosen to take into account each child’s peak alpha frequency (PAF) or to a waiting list control group. Each trained child underwent 19-channel electroencephalography (EEG). All children had average intelligence and none were receiving treatment, such as medications, for ADHD. Prior to the training, MOXO and n-back tests were performed. Next, neurofeedback training sessions with frequency bands for theta and beta ranges determined using each child’s PAF were carried out for 10 weeks. Training parameters were set to increase amplitudes in the low beta range and to decrease amplitudes in the theta and high beta frequency ranges. The n-back test was performed again right after the training and then a year later. Results. During the first n-back test, children from both groups responded correctly to more than 43% of the stimuli. During the second test, children from the waiting list responded correctly to an average of 49% of the stimuli, while children who underwent the neurofeedback training were correct, on average, 69% of the time (significant difference, P < .001). During the third n-back test a year later, children from the waiting list responded correctly to 53% of the stimuli, while those who underwent the neurofeedback training responded correctly to nearly 71%. Conclusion. This study found a statistically significant improvement in a measure of working memory in children who did 10 to 12 sessions of neurofeedback training with training frequency ranges for theta and beta defined according to each child’s PAF. The beneficial effects were still present a year after training.

It is important to optimize working memory because it transforms, synergizes and constantly updates new and old information. One way to optimize working memory is to listen to Murottal Al-Qur'an, because it has a harmonious tone which can stabilize the mind to properly process the information. This study aims to determine the effect of listening to the Al-Quran murottal on working memory. The research subjects were 24 students of Psikologi 2017, grouped equally in the control and experimental groups. An experimental intervention was administered for 15 consecutive days lasting 15 minutes and 52 seconds. Measurements in working memory use Operation Span Task, Reading Span Task and Symmetry Span Task. The design of the study used a pre-test post-test control group and the data were analyzed by t-test. The results showed a significant difference between the control group and the experimental group on the symmetry span task subtest (p = 0.044, p <0.05).

Introduction: Attention Deficit Hyperactivity Disorder (ADHD) may develop during the preschool years of the child and extend into adulthood. ADHD also leads to impaired Working Memory (WM) creating problems in various functions. Aim: To compare the effectiveness of behavioural parent training and structured games on WM of children with ADHD. Materials and Methods: This prospective interventional study was conducted in 18 schools of Ghaziabad City, Uttar Pradesh, India. Seventy subjects were selected based on Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) criteria. Group A (n=35) received structured games and Group B (n=35) received Behavioural Parent Training (BPT). Seguin Form Board Test Time (SFBTT) was recorded as outcome on baseline and 5th week. Student’s paired and unpaired t-test was done. SPSS 22.0 version was the software used and p<0.05 was considered as level of significance. Results: Analysed data showed significant results within structured games group with t=2.355, p<0.05, and no significant result within BPT group with t=-0.776, p>0.05. Between group comparison showed significant difference with t=-2.804, p<0.05. Conclusion: Training of WM in form of structured games can be an effective method when compared to BPT in children with ADHD.

Beneficial effects of relaxation on cardiovascular and immune functions and on memory has been implied but an empirical relationship between task performance and anxiety reduction has not been reported. In this study, we investigated whether guided imagery of relatively short duration would decrease S-Anxiety and electroencephalogram Bispectral Index and improve working memory. 42 participants (age: M = 39, SD = 11, 14 men, 28 women, university students and VA Medical Center employees, recruited by their professor or by fellow employees) underwent relaxation by 16-min. guided imagery or no treatment (control). Spielberger's State-Trait Anxiety Inventory and the WAIS–III Letter-Number Sequencing Test were administered before and after relaxation. S-Anxiety and BIS Index decreased and the Letter-Number test score increased by 30% after relaxation but not in the control group. This score was higher for participants with low anxiety and BIS Index. There was no significant difference between the groups before treatment. The results suggest that guided imagery of short duration produces relaxation as measured by psychological and neurophysiological indices and improves working memory performance.

Aim: The aim of this study is to compare the effect of exercise training on physical capacity and alcohol consumption in alcohol use disorder (AUD) patients. Methods: One hundred and five AUD patients were randomly assigned to treatment as usual combined with running and brisk walking for 30–45 min twice a week, either in small supervised groups (GR) or individually (IND), or to a control group with no running (C). Assessments were made after 6 and 12 months of training. Results: Training volume was estimated as 36 min per training bout at an intensity of 78% of HRmax with no differences between GR and IND ( p>.05). A highly significant reduction in training frequency was seen in both training groups after the first month ( p<.0001). Only IND increased VO2max, by 5.7% ( p<.05), while no differences were seen between GR, IND and C. Alcohol intake decreased from 219 to 41 units per 30 days as the average for the entire sample with no significant difference of drinking outcomes between groups ( p<.0001). Conclusions: We saw an effect on drinking habits after running in both groups. However, no additional effect was seen when compared with the control group. A drop in the training frequency during the intervention might have resulted in an insignificant training stimulus.

The aim of this paper was to examine the role of phonological working memory in specific mental arithmetic difficulties and general arithmetic learning difficulties (ALD; difficulties presenting in both mental arithmetic and written arithmetic). In Study 1, we categorized 53 sixth graders into a control group, a group with specific mental arithmetic difficulties, and a group with general ALD. The findings indicated the group with specific mental arithmetic difficulties performed significantly worse on the task involving phonological working memory than did the control group. However, a significant difference was not found between the group with general ALD and the control group. In Study 2 involving 54 sixth graders, we decreased the load of phonological working memory by changing the format of the problems from horizontal (more reliance on phonological codes) to vertical (more reliance on visual resources). We found that the group with specific mental arithmetic difficulties performed comparably to the control group. In other words, when the working memory load is reduced, they no longer lag significantly behind on mental arithmetic. However, the group with general ALD still performed significantly worse than the control group when the problems were presented vertically, indicating that reduced phonological working memory load did not alleviate their arithmetic difficulties. The findings in both studies suggested that poor phonological working memory might contribute to the underlying mechanism for specific mental arithmetic difficulties but not as much for general ALD.

Objective To compare frequency of sleep disorders (SD) and executive dysfunction (ED) in children with attention deficit-hyperactivity disorder (ADHD) and a control group. Method We studied 156 children with ADHD with a mean age of 8.5 years, and a control group with 111 children with a mean age of 8.3 years. We utilized the Pediatric Sleep Questionnaire (PSQ) to screen SD and the working memory measurement from the Wechsler intelligence scale for children (WISC-IV) to screen ED. Results We did not observe an increased frequency of SD in children with ADHD compared with the controls. However, we did identify ED in children with ADHD; additionally a significant correlation was observed between the type of ADHD and SD and among ED, WISC-IV measurements, and type of SD in children with ADHD. Conclusion An increase of SD frequency in children with ADHD was not observed, but we did identify ED in children with ADHD. Additionally, a correlation among ADHD types, SD, ED, and WISC-IV measurements was observed in children with ADHD.

In hypercatabolic patients, the beneficial effects of glutamine on gut mucosa could be partly due to a stimulation of protein synthesis. The fractional synthesis rate (FSR) of gut mucosal protein was measured in four groups of healthy volunteers treated with glucocorticoids for 2 days. Two groups were studied in the postabsorptive state while receiving glutamine or a nitrogen equivalent (control) and two groups in the fed state with or without glutamine, using a 5-h intravenous infusion of [13C]leucine, [2H5]phenylalanine, and cortisone. After nutrient and tracer infusion, duodenal biopsies were taken. In the postabsorptive state, FSR of gut mucosal protein were 87 and 76%/day in the control group and 130% ( P = 0.058 vs. control) and 104% ( P = 0.17 vs. control)/day in the glutamine group, with leucine and phenylalanine as tracers, respectively. During feeding, FSR did not increase and no significant difference was observed between glutamine and control groups. Overall, FSR of the four groups were two- to threefold higher than those obtained previously in healthy humans, suggesting that glucocorticoids may increase gut mucosal protein synthesis. However, in this situation, a moderate enteral glutamine supply failed to demonstrate a significant effect on gut mucosal protein synthesis in the postabsorptive state and during feeding.

Background: Subjective memory complaints are a key component in mild cognitive impairment (MCI) diagnosis. However, studies that examined memory awareness among MCI participants have published contradictory results. One possible explanation for the inconsistent findings could be the disregard from the multidimensional structure of subjective memory. Objectives: The present study is directed at assessing subjective memory among healthy and MCI participants, referring to three main types of memory: episodic, semantic, and working memory. Method: Participants were 123 adults (aged 50-90). They were divided into two groups, the MCI group, and the control group, according to their objective cognitive performance in RAVL or Mo- CA tests. All participants filled a subjective memory questionnaire, assessing their awareness of episodic, semantic, and working memory. Results: MCI participants estimated their semantic memory as significantly lower in comparison to the estimation of the healthy controls. By contrast, MCI participants showed an overestimation of their episodic memory capabilities compared to the control group. No significant difference was found between groups (MCI and healthy controls) in evaluating their working memory. In addi- tion, for both groups, Pearson’s correlation revealed a significant negative correlation between age and semantic memory evaluation. Such correlation was not found for subjective episodic memory. Discussion: Findings suggest that while people with MCI exhibit poor awareness of their episodic and working memory capabilities, their awareness of their decrease in semantic memory is appar- ently intact. Therefore, it is suggested that when using the self-report criterion for MCI diagnosis, clinicians should consider the patient’s’ semantic memory complaints.

The present study aimed to investigate whether working memory (WM) and planning performances can be enhanced using transcranial direct current stimulation (tDCS). A total of 30 healthy individuals were randomly assigned to two groups: active (A)-tDCS and control (S)-tDCS. Anodal stimulation over the left dorsolateral prefrontal cortex (DLPFC) (F3) and cathodal stimulation over the right orbitofrontal cortex (OFC) (FP2) were further implemented at 2 mA in the A-tDCS group, while there was no intervention in the control group. The tools used were software versions of the three-level n-back task and Tower of London (TOL) task, and for each task we measured participants’ response accuracy and response time. The results showed a significant difference between the groups in both cognitive functions, suggesting that tDCS can improve response accuracy in memory and problem-solving ability, but it is less effective in terms of improving response time on planning. Overall, findings suggest that tDCS can enhance WM and planning performances.
