The effectiveness of Transcranial direct current stimulation (tDCS) on working memory in patients with major depression

The aim of this study was to evaluate the effectiveness of of transcranial direct current stimulation (tDCS) on working memory in patients with major depression.
The research method was quasi-experimental with pretest and post-test and follow-up with control group. The research population comprised female outpatient referrals to private psychiatric centers and psychological counseling centers in Tehran in the first half of 2016, They had received a diagnosis of depression by a psychiatrist at least once. Of these, 30 females were selected as a sample group with convenience sampling method and based on the criteria of inclusion and exclusion and were divided randomly into two groups , experimental (n = 15) and control (n = 15) group. The experimental group received transcranial direct current stimulation (tDCS) in 10 sessions, While this intervention was not provided to the control group. The data were collected by N-BACK. Analysis of variance with repeated measurments was used to test the research hypothesis.
The results showed that transcranial direct current stimulation (tDCS) had a significant effect on increasing working memory and the impact will continue to follow up.
Therefore, this approach can be used to improve working memory in people with major depression.
