BackgroundThe use of Transcranial Magnetic Stimulation (TMS) in the add-on treatment of patients with treatment-resistant depression (TRD) is becoming more common. This study aims to investigate the efficacy of TMS on depression and accompanying anxiety symptoms among patients with TRD.MethodsThe current study was conducted with 38 patients diagnosed with TRD. The patients were randomly divided into two groups and received 20 sessions of high-frequency (10Hz) TMS and 20 sessions of sham TMS to the left dorsolateral prefrontal cortex in a double-blind and cross-over fashion without a change in their pharmacotherapy. In the clinical evaluation, Hamilton Depression Rating Scale (HAM-D) and Hamilton Anxiety Rating Scale (HAM-A) were carried out three times in total: before, crossover phase, and at the end of the treatment.ResultsA statistically significant decrease was found in the HAM-D and HAM-A in the group who were actively stimulated in the cross-over phase of the study. While there was a significant decrease in the HAM-A in the group who received sham stimulation, the decrease in the HAM-D was not statistically significant. Group comparisons revealed a statistically significant decrease in HAM-D in the group who were actively stimulated compared to the group receiving sham stimulation. At the end of the study, 63% of 38 patients responded to treatment, 15% partially responded, and 42% reached remission.DiscussionThis randomized, double-blind, sham-controlled, cross-over study revealed that TMS is superior to sham-TMS, provides clinically significant improvement when implemented besides pharmacotherapy among patients with treatment-resistant depression, and is beneficial for accompanying anxiety symptoms.
