Assessment of Efficacy of transcranial Direct Current Stimulation (tDCS) and Repetitive Transcranial Magnetic Stimulation on Depression Symptom's Reduction

Depression is a common disorder, therefore, it is very important to identify effective and permanent treatment. The aim of the present research was to compare two cases of new non-invaing treatments, the efficacy of transcranial direct current stimulation therapy and repetitive transcranial magnetic stimulation on depression symptoms’ reduction.
To do so, 20 patient with depression where selected and were randomly assigned to two groups; i.e. transcranial direct current stimulation therapy and repetitive transcranial magnetic stimulation. Subjects completed the Beck Depression Inventory through pretest, posttest and follow up intervals. The data were analyzed using repeated measure of analysis of variance.
Findings: The finding revealed that both treatments were effective in reducing depression symptoms but, no significant difference was found between the two methods. However, there was a difference between the groups in follow up scores. The mean of scores of follow up condition had a change inrelation to the rTMS group.
The results of the study indicated the superiority of the effectiveness of repetitive transcranial magnetic stimulation, the other treatment was more in the course of time.
