Objective The current study aimed to investigate the impact of transcranial alternating current stimulation (tACS) on working memory and selective attention in athletes with attention deficit hyperactivity disorder (ADHD). MethodsIn total 45 athletes with attention deficit hyperactivity disorder were randomly divided into three equal groups (sham, control and experimental groups). All participants in the sham and experimental groups received stimulations on the F3 and SO with a current of (10 HZ) 1 mA for 15 min over 10 sessions (P ≤ 0.05), and after 10 sessions, each group was retested. After 2 weeks, a follow-up test was performed according to the post-test using the Stroop test and N-BACK-(working memory test) to test statistical hypotheses (P ≤ 0.05). ResultsThe results of repeated measures analysis of variance revealed that applying tACS proved effective in improving the working memory and selective attention of ADHD athletes. ConclusionsThe study's findings indicated that the protocol of applying tACS 1 MA with 10 HZ improved the working memory and selective attention of ADHD athletes.

Introduction: One of the most common childhood disorders considered by psychologists and psychiatrists is Attention Deficit/Hyperactivity Disorder, which leads to attention deficit, hyperactivity and impulsivity in affected people. Aim:The purpose of this study was to investigate the impact of Chess training in students with ADHD. Method:The statistical community of the present quasi-experimental study was 76 students with ADHD in Khorramabad city in the academic year of 2019-2020. 32 students were selected by convenience sampling and randomly divided into two groups of 16 controls and experiments based on age, sex and pre-test results. And the experimental group received chess training for 11 consecutive weeks and a weekly session of 60 to 90 minutes. Subjects were evaluated three times (pre-test, post-test, two-week follow-up) with Connors and Swanson questionnaires and data were analyzed by ANOVA and Bonferroni test and Spss 21 software. Results:The results of the study showed a direct and high correlation between the results obtained from both Swanson and Connors measuring instruments and the positive effect of chess training on students with ADHD. (P=0.001, F=20.17). Conclusions:Due to the positive effect of Chess training on the symptoms of ADHD, it is suggested that Chess training be used to reduce the symptoms of ADHD.

Introduction: Attention Deficit Hyperactivity Disorder is a childhood disorder that is associated with a persistent pattern of symptoms of inattention, hyperactivity or inappropriate impulsivity, which usually continues into adulthood. Aim: The purpose of this study was to investigate the impact of the video game Minecraft on the Cognitive flexibility of ADHD athletes students. Method: The study was a quasi-experimental study with a pre, post and follow-up design with a control group. The statistical population of the study was 79 ADHD athletes students from 9 to 16 years old in 2020 in Lorestan province. Of these, 30 students were randomly selected and divided into two groups control and experimental. Subjects were evaluated three times (pretest, posttest, follow up) with Wisconsin Card Sorting Test. Also, to test the hypothesis, multivariate analysis of covariance, repeated measures analysis of variance, Bonferroni test and Spss 26 software at the significance level of 0.05 were used. Results: The results of cognitive flexibility scores showed a significant difference between the two groups in the three stages of measurement (P=0.0001). Bonferroni showed a significant difference between groups in the components of cognitive flexibility, the number of categories (P=0.027) and preservation error (P=0.0001). That is, Minecraft improved Cognitive flexibility in the experimental group, but no change was observed in the cognitive flexibility of the control group. Conclusion: It can be concluded that Minecraft improves the cognitive flexibility of ADHD athletes student.
