강박장애에 대한 경두개 직류자극술의 적용

Abstract

Treating obsessive-compulsive disorder (OCD) is a difficult challenge since less than a half of the OCD patients show a significant treatment response to 1st line treatment. Therefore, various treatment tools including brain stimulation methods have been studied to solve the treatment-resistance of OCD. Transcranial direct current stimulation (tDCS) is one of the emerging treatment options for OCD. In this review, literatures on tDCS for OCD treatment were evaluated by assessing the treatment effects and safety issues. In most studies, tDCS caused a significant improvement in treatment-resistant OCD without serious adverse event, although its settings including electrode positions and polarity remain unestablished. Further studies are needed to develop protocols for applying tDCS in OCD and to strengthen the evidence of its efficacy.
