Objective: The present study aimed to investigate the effectiveness of Transcranial Direct Current Stimulation (tDCS) on neurocognitive performance in people with mild neurocognitive impairment. Using meta-analysis and integrating the research results, this study has examined the extent of the effect of Transcranial Direct Current Stimulation on the improvement of neurocognitive function in people with mild neurocognitive impairment.
Method: For collecting data for meta-analyses, Magiran, SID, and Irandoc databases were used to search Persian articles and Science direct, Scopus, and PubMed databases were used to find foreign articles by the use of keywords of ‘MCI’, ‘transcranial direct current stimulation’, tDCS, and ‘mild cognitive impairment’ and their equivalences for Persian articles. Of the 29 studies, 11 methodologically acceptable were meta-analyzed. The research tool was a meta-analysis checklist.
Results: The results of the study indicated publication bias in the studies. Due to the heterogeneity of the studies, a random-effect model was used. The effect of Hedges for the impact of Transcranial Direct Current Stimulation on neurocognitive functions in people with mild neurocognitive impairment was 0.26, which was a large effect.
Conclusion: This result shows that clinicians can choose transcranial direct current stimulation (tDCS) as an effective intervention for patients who suffer from mild cognitive impairments. More investigations are necessary to find out the cognitive benefits of using transcranial direct current stimulation in elderly people and other cognitive impaired persons.

Abstract Background: In this survey, the intervention of cognitive behavioral stress management (CBSM) on psychological and immune indices and pain in patients with Rheumatoid Arthritis is studied. Method: Statistical population of the study consisted of patients who referred to the rheumatology clinics in the northern parts of Tehran. 44 participants aged 25–60 using purposive sampling in accordance with inclusion and exclusion criteria selected and in two groups of 22 individuals were examined. Psychological, immune and pain evaluation tests of depression, anxiety and stress scale, blood sample, and McGill pain inventory were conducted in two stages of pretest and posttest using multiple covariance analysis. Results: The results showed a significant effect of the stress management intervention on depression (F1,37=4/318, P= 0/046, η2 =0/104) among patients with RA. The use of this intervention was effective in reducing the immune parameter (CRP) (F1,38= 17/593, P= 0/001, η2 =0/316) and their pain (F1,39= 4/885, P= 0/033, η2 =0/111). Conclusion: According to the results, employing this method for RA patients is very helpful and it can be suggested for improving their psychological and physical conditions.
