title: [Historical review and recent research trends of the antidepressant repetitive transcranial magnetic stimulation (rTMS)].
abstract: The antidepressant effect of repetitive transcranial magnetic stimulation (rTMS) has been studied intensively over the last years. Numerous studies worldwide yielded variable results ranging from ineffectivity to an efficacy rate of more than 50 % for the reduction of depressive symptoms. A comparison of the effectiveness of TMS across studies is difficult due to the variety of chosen stimulation parameters, different inclusion criteria, and different designs. The discrepancies in results could be partially in account to these factors. From a pathophysiological point of view, there are no empirically justified parameters published carrying out an antidepressant TMS. Further studies are required to find optimal stimulation parameters using complementary methods like functional imaging techniques or regarding other factors that could interfere with its efficacy. An overview of studies published in the last ten years, a critical analysis of stimulation procedures and protocols, and possible future perspectives of this method are reviewed in this article.
