Aim: One of the most common problems in people with multiple sclerosis)MS) is memory impairment. Although the effect of dual cognitive motor tasks assignments on cognitive function in MS patients have been confirmed, however little research has been done its effect on their spatial memory. Therefore, the aim of this study was to improve spatial memory of MS patients because of dual tasks training. Method: The present study's design was pre-test and post-test with random group method. The research method was semi-experimental and in terms of purpose was applied. To did this research, Thirty women with MS)20-60 years old) who were members of the MS Association of Tehran, participated voluntarity with informed consent in this study. participant were then randomly divided into control and experimental groups. the spatial memory pre-test was first taken from the subjects through spatial memory from the LM-01 spatial memory device. then subjects training Dual Task for eight weeks, each consisting of two 45-60 minutes sessions. The Post-test was done. The data were analyzed by mix analyasis and independent and paired t-test at a significant level of p < /em>≤0/05. Result: Results of analysis of variance showed that dual task training significantly improved spatial memory)p < /em> = 0.04) in the experimental group compared to the control group. Conclusion: Therefore, Dual Task training cognitive-motor assignments causes more mind involvement and can be considered as a suitable way to enhance cognitive abilities such as spatial memory.

Aim: Schizophrenia is one of the most prevalent severe psychiatric disorders that including variety of cognitive, emotional & behavioral symptoms in which formal thought problem is one of the determinant factors of prognosis. The aim of the study was comparison of cortical activities in schizophrenic patients with & without formal thought. Method: 60 schizophrenic patients(31 patients with formal thought disorder & 29 patients without formal thought disorder) were selected by goal oriented sampling procedure based on including & excluding criteria. Cortical activities of all participants recorded by 19 channels EEG. Findings: Data showed to schizophrenics without formal thought disorders, the absolute power of delta & beta bands were lower & theta band was higher in patients with formal thought disorder in anterior regions. Also, patients with formal thought disorder revealed decreased absolute power in delta, alpha & beta bands in posterior regions. Conclusion: Our results are in favor of hypofrontality hypothesis of schizophrenia & indicated that patients with formal thought disorder, had cortical hypo arousal that result in severe cognitive problems.

Aim: the most common of which is disordered reading or dyslexia This study investigated the effectiveness of Neurofeedback on Cognitive Deficits and visual–motor perception in the dyslexic students. Methods: Present research was a quasi-experimental Method with pretest-posttest and control group design. The population included 8 to 11 years old pupils with dyslexia in Tehran city. The sample consisted of 40 students with dyslexia that are selected and randomly assigned to two experimental and control groups(each group n = 20). Finally, the study was performed with 33 patients(16 in experimental group and 17 in control group). In this study the experimental group received sessionsof neurofeedback training First, given three times a week(for one month) and then twice a week(one month) for 45 minutes, while the control group did not receive this training. The instruments used in this study were the Tower of London software, Stroop, continuous operation test, n-back test and Bender-Gestalt visual-motor coordination . Data were analyzed using multivariate covariance analysis using SPSS version 20 software. Results :The results showed that Neurofeedback on Cognitive Deficits in terms of reduced time and increased total points in the Tower of London, committing and remove errorsand time in continuous operation test, and reduce the amount of time keeping, time incongruent, inconsistent error in Stroop test and correct response in n-back test(P˂ 0.05); and visual-motor coordination in terms of distortion, rotation, Lack of integration and repeatness is effective on dyslexic individuals(P˂ 0.01).A. Conclusion: ccording to the findings concluded that Neurofeedback is effective way to improve symptoms of dyslexic children.

Aim: The purpose of this study was to investigate the Effectiveness of rehabilitation, using Dohsa-Hou, on auditory memory and problem solving in children with learning disorder and auditory discrimination problem in Esfahan. Method: The research method was semi-experimental and study conducted in the form of a pretest-post-test with control group design. The target community of all children with learning disorder in Esfahan which has some forms of auditory discrimination problem. One of the centers of learning disabilities in Isfahan province was referred to the Center for New Immune Disorders, and then among those who had entry criteria, 30 individuals were selected through available sampling method and then randomly assigned into two groups of experimental and control. After doing the pretest in the two groups, the experimental group received 10 therapy sessions Dohsa-Hou rehabilitation, each lasting 60 minutes. Both groups were then subjected to post-test and follow-up. Data were collected using Hepner problem solving questionnaires(1982) and active memory of Dainiman and Carpenter(1980). Data were analyzed using covariance analysis. Result: after rehabilitation sessions, the mean in problem solving and memory in experimental group significantly increase compared to their previous levels(p<0/001). In control group no significant difference was found. Conclusion: rehabilitation, using Dohsa-Hou was effective in improving acoustic memory and problem solving in children with learning disorder and auditory discrimination problem.

Aim: Depression is the most common mental disorder in the world. Mindfulness-based group cognitive therapy is one of the effective treatments, and transcranial direct-current stimulation is one of the new treatments for depression. This study aimed to compare the efficacy of these two therapies in reducing depression. Methods: This was a quasi-experimental study with pre-test and post-test with control group. Subjects were 60 students with depressive symptoms who were screened with General Health Questionnaire and selected by purposeful method based on Beck Depression Inventory(score above 15), and divided randomly into 4 groups of fifteen, including mindfulness-based cognitive therapy, transcranial direct-current stimulation, sham group(mock stimulation), and control group, and were reassessed in post-test using Beck Depression Inventory. The data were analyzed by repeated measurements design using SPSS software version 22. Results: The results showed that both experimental groups had a significant decrease in post-test depression scores(p<0/05), while there was no significant difference in sham and control groups. There was no significant difference between the two experimental groups in mindfulness-based group cognitive therapy and transcranial direct-current stimulation(p>0/05). Conclusion: Mindfulness-based group cognitive therapy and transcranial direct-current stimulation are effective in reducing depression in the nonclinical population.

Aim: The aim of this study was to determine the relationship between executive functions of the brain with attention deficit hyperactivity disorder. Method: For this purpose, in the form of a correlation design, the students of Tabriz University in the academic year of 98-99 were selected by cluster random sampling. Data were collected using Conners Ill Symptom Checklist, Stroop Test, Wisconsin Cards, and Wechsler Working Memory. Results: Data analysis using structural equation modeling showed that the functions of organization, accuracy and concentration, working memory, problem solving and inhibition were able to significantly determine changes in attention deficit and hyperactivity symptoms. Conclusion: The executive functions of the brain have a negative role in attention deficit hyperactivity disorder and deficiency in these functions may predispose to attention deficit hyperactivity disorder. Therefore, in current etiology of attention deficit and hyperactivity, it is necessary to emphasize the evaluation of executive functions and to consider executive dysfunction as the neurological basis of attention deficit and hyperactivity disorder..
