The present study was conducted to investigate the effectiveness of transcranial direct current stimulation (TDCS) on the improvement of mental health of divorced women referred to counseling centers. The research method was semi-experimental and pre-test-post-test design with control and follow-up groups. The statistical population of the research included divorced women who were referred to counseling centers in Ardabil city. Among them, 30 people were selected by convenience sampling and randomly assigned to two experimental and control groups. The tool used in the research was Symptom Checklist-90-Revised (SCL-90-R). The intervention was carried out using a transcranial direct current stimulation device on the experimental group members for 10 consecutive sessions (20 minutes each session) by placing the anode in the F3 section and the cathode in the FP2 section.The data were analyzed using the statistical method of analysis of covariance with repeated measures. The findings of the research showed that there is a significant difference between the two experimental and control groups in terms of mental health and its subscales, including depression, anxiety, obsessive-compulsive disorder, aggression, and psychosis (P<0.001). these results indicated the effectiveness of transcranial direct current stimulation on the mental health of divorced women. Overall, the research findings highlight the role and importance of TDCS treatment in improving mental health. According to the results, it seems that the left frontal cortex plays an important role in people's mental health. Therefore, with the electrical stimulation of this part of the brain, it can help a lot to improve people's mental health.

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.

Introduction: Major depression is the most common psychiatric disorder and in the world has the greatest impact of all biomedical diseases on disability. The purpose of the present study is comparing the expression of dopaminergic DRD3 and DRD4 receptors in patients with major depression and healthy Individuals. Methods: The population of this study was, all depressed patients admitted to the clinical psychologists. The method is causal-comparative study. The research sample includes of 62 depressed patients (28 male and 34 female), with the random sampling of depressed patients referred to the clinics, to be selected, and 60 healthy individuals(30 male and 30 female) as comparison group. After the informed consent.Evaluate the relative expression of gene DRD3 and DRD4, using measured by quantitative Real-Time RT-PCR and SYBER Green used. Research data was analyzed using the T-Test, SPSS and Excel software. Results: Results showed that DRD3 gene in patients compared to healthy subjects had greater relative expression(p value<0.001),but the D4 gene expression in the two groups showed no significant difference (p >0.05).The finding suggest that DRD3 gene seem to be important variables in depression, but DRD4genedoes not play a role in depression. Conclusions: The finding suggest that he DRD3 receptor gene seem to be an important variable in depression, which showed decreased expression of receptor DRD3,under the influence of this disease, which we can be used as a marker for to screen major depression disorder (MDD) correctly.

Objective: The aim of this study was to determine the effectiveness of neurofeedback therapy and transcranial direct currect stimulation in improving cognitive dominance in children with ADHD. Method: The present study is a quasi-experimental study with pretest-posttest and control group. The statistical population includes all children with attention deficit/ hyperactivity disorder in Ardabil in the academic year 1399-1400. The sample consisted of 33 children with attention deficit/ hyperactivity disorder who were selected by convenience sampling method and randomly assigned to two intervention groups and a control group(11 people in each group). The instruments of this study include WISC-IV intelligence test and the interventions of this study include 20 sessions of neurofeedback therapy and 10 sessions of transcranial direct currect stimulation. The data of this study were analyzed with SPSS software version 23. Results: The mean scores of cognitive dominance were measured twice, which showed that in the post-test, the mean scores in cognitive dominance increased and no change was observed in the control group. The results show that after controlling the effect of pretest on posttest to compare the scores of the cognitive dominance scale between the three groups at the error level(0.05) there is a significant difference. Conclusion: According to the sessions and results obtained, neurofeedback therapy and transcranial direct currect stimulation are effective in improving cognitive dominance; Therefore, it is recommended to use these treatments to improve cognitive dominance.
