Abstract

Multiple sclerosis (MS) is a demyelinating disease of the CNS that due to cognitive impairment, can reduce the quality of life in these patients. The aim of this study is to evaluate effect of computerized cognitive rehabilitation on prospective & working memory function in Multiple Sclerosis patients. 46 MS patients aged 20–40 who have the inclusion criteria, were randomly assigned to experimental and waiting-list control groups. Experimental group trained for 12 session with a Memory rehabilitation software and waiting-list control group did not receive any intervention and training of this group was postponed after conducting research. Daneman and Carpenter's capacity working memory and Retrospective-Prospective Memory Scale was applied at pretest, posttest, and follow-up. The results of repeated measures ANOVA showed a significant difference between the means of working memory in experimental and waiting-list control groups. Also, the results of the present study indicate that a significant difference between the means of prospective memory in experimental and waiting-list control groups. Moreover, the post-test and follow-up scores in the experimental group was not statistically different. So Computerized cognitive rehabilitation have significant effect on prospective and working memory performance in patients with Multiple sclerosis and it can be used as an effective and helpful method to improve memory performance of these patients.

Abstract

The aim of this study was to evaluate the effectiveness of cognitive rehabilitation on improving working memory of adolescents with traumatic brain injury. The method of this research was quasi-experimental pre-test-post-test with control and follow-up groups. To conduct this study, 20 adolescents aged 9-18 years with traumatic brain injury referred to medical centers in Sadaf Shahriar (Parandmehr Clinic) were selected by convenience sampling and randomly assigned to two groups of 10 experimental and control. To measure the dependent variable of working memory, Wechsler scale 4 subtests (auditory measurement of working memory) and Benton test (visual-spatial measurement of working memory) were used. The experimental group underwent cognitive rehabilitation intervention (12 sessions of 45 minutes). Analysis of variance with repeated measures was used to analyze the data. The results showed that there was a significant difference between the experimental and control groups in pre-test, post-test and follow-up of working memory performance. The results showed a significant difference between the mean scores of working memory (auditory and visual-spatial measurements) of the experimental group and the control group in the post-test. In addition, there was no significant difference between post-test scores and follow-up in the experimental group, which showed the effect of cognitive rehabilitative perstability on working memory performance in adolescents with brain injury. Therefore, cognitive rehabilitation has a significant effect on improving working memory performance in patients with brain injury and can be used as an effective and useful method to improve working memory performance in adolescents with brain damage.

Abstract
The purpose of this study was to investigate the effect of computer-based cognitive rehabilitation on cognitive regulation of emotion and emotion understanding in children with specific learning disorders. This research was conducted in a semi-experimental way (pre-test - post-test with a control and follow-up group). The statistical population of this study consisted of all the students with specific learning disorders (10-12 years old), who had been referred to the learning disorders center in Ardabil between the first of October and the middle of November 2017 (123 people). 30 of them were selected through purposive sampling (selection of volunteer students to participate in the research) (16 boys and 14 girls) and the emotional regulation questionnaires of Garnefsky et al. in identifying emotions and difficulty in describing emotions) were completed in three stages. The students of the experimental group completed the tasks of the cognitive rehabilitation package in 12 sessions of 45 minutes in a period of four weeks. The results of the covariance analysis of the data showed that the cognitive rehabilitation package based on a computer has an effect on improving rumination, positive refocusing, refocusing on planning, positive reappraisal, and acceptance of cognitive regulation of emotions in children with specific learning disorders, as well as understanding their emotions. The significance and comparison of the post-test results with the one-month follow-up test indicate the stability of this effect. Therefore, since these students are facing problems in cognitive regulation and emotional understanding, such interventions can solve their problems in this field.
