The purpose of this study was to compare the effectiveness of the tDCS method and short-term cognitive rehabilitation protocol on verbal fluency and visuospatial ability in the elderly with mild Alzheimer's disease. Methods: The research method was an extended experiment with two experimental groups and one control group, which was conducted using the pre-test and post-test method. The statistical population included elderly people over 65 years of age with mild Alzheimer's who lived in Ardabil who had been referred to a neurologist in 2022,among these people, 60 people were randomly selected into two groups. An experimental and a control group were assigned. Then tDCS method was applied for 10 sessions of 20 minutes in one experimental group and short-term cognitive rehabilitation program for 9 sessions of 90 minutes was applied in the second experimental group and no intervention was performed in the third group. The post-test was conducted at an interval of one week. After one month, the studied groups were followed up again. Aden Brook's revised version of the cognitive test was used to collect data. Findings: The results showed that tDCS significantly improves the visual component and the cognitive rehabilitation method improves perception. In general, it seems that the performed interventions improved visual spatial ability in the elderly with mild Alzheimer's disease, while they had no significant effect on the variable of verbal fluency. Conclusion: It can be concluded that both methods can be used to improve the spatial visual ability of the elderly with mild Alzheimer's disease.

Objective: The present study was conducted with the aim of Comparing the effectiveness of transcranial direct current stimulation and repeated Transcranial Magnetic Stimulation treatment on working memory, impulsivity and self-harm behaviors in people with borderline personality. Method: The current research is semi-experimental with pre-test-post-test and control groups. The statistical population of this research includes the clients of some counseling centers in Ardabil city in 1401. The sample of this study consisted of 45 people with borderline personality disorder who were selected by the available sampling method. This study included 3 groups and each group included 15 people. Each subject was randomly assigned to two treatment groups (tDCS and rTMS) and a control group. The tools of this research included N-back working memory test, Barratt Impulsivity questionnaire, self-harm questionnaire, tDCS and rTMS.Findings: The results showed that the treatment of tDCS and rTMS has a significant effect on impulsivity, working memory and self-harm in borderline personality disorder patients. And the results show that after controlling the effect of the pre-test on the post-test to compare scores, working memory, impulsivity and self-harm among the three groups, there is a significant difference at the error level (0.05). The results of Bonferroni's post hoc test also showed that between the effectiveness of the two treatment methods, rTMS treatment was more effective than tDCS. Conclusion: The results showed that tDCS and rTMS led to the improvement of working memory in people with borderline personality disorder and also reduced the level of impulsivity and self-harm behaviors.

Introduction: Emotional problems, psychological distress and cravings are some of the side effects of substance abuse. The aim of this study was compare the effect of transcranial direct current stimulation and Methadone Maintenance treatment on craving reduction, emotion regulation and distress tolerance in people with opioid use disorder. Method: The present study was a quasi-experimental. The statistical population of this study was all people admitted to addiction treatment clinics in Hamedan in 2019, which 40 patients were selected by available and voluntary sampling in two experimental groups of methadone therapy (n = 13), electrical brain stimulation (n = 13) and a control group (n = 14). Subjects completed the Emotion Regulation Difficulty Scale, Distress Tolerance Scale, and measure the temptation of substances after leaving. Data were analyzed by analysis of covariance. Results: The results showed that electrical stimulation had a significant effect on craving, emotion regulation and distress tolerance (p <0.05). Methadone therapy was effective in craving reduction and emotion regulation, but had no effect on distress tolerance. In comparison between the two experimental groups, no significant difference was observed in craving reduction (p> 0.05), but the effect of electrical stimulation on emotion regulation was greater. Conclusion: Due to the greater effect of transcranial direct current stimulation on emotion regulation and distress tolerance, it can be used as an effective and complementary treatment, along with the usual treatments for substance use disorder and the emotional distress it caused.

Introduction: The aim of this study was to effectiveness of metacognitive therapy and transcranial direct current stimulation on the executive functions of veterans with post-traumatic stress disorder. Methods: The present study is a quasi-experimental study and its research design is pre-test and post-test with a control group. Sixty PTSD veterans of Bustan Psychiatric Hospital in Ahvaz participated in study as a sample and were randomly divided into three groups of metacognitive therapy, tDCS and control. The measuring instruments were the Stroop test and the Tower of London test. Data were analyzed using ANCOVA. Results: the results showed that in the executive function test of Stroop and Tower of London in the pre-test stage there was no significant difference between groups (P <0.05) but in the post-test stage there was a significant difference between groups (0.05 > P). According to the results of Bonferroni test, there is a significant difference between the metacognitive therapy group with control (P<0.05) and tDCS with control (P<0.05) in strop and Tower of London test, but there is none significant difference between the metacognitive therapy and tDCS groups (P <0.05). Conclusion: use of metacognitive therapy approach as well as tDCS of can improve executive functions in veterans with PTSD. Therefore, it is recommended to therapists and rehabilitators and all people who deal with such people to use these two types of approaches in their daily plans and to improve executive functions.
