Introduction: Transcranial Direct Current Stimulation (tDCS) can improve or impair the function of the brain. Deficiency in response inhibition has been considered as one of the causes of psychiatric disorders, such as obsessive-compulsive disorder (OCD). The present investigation scrutinized the effect of transcranial direct current stimulation through simultaneous uni-side anodal on response inhibition in patients suffering from OCD. Materials and Methods: The participants were 25 patients who referred to Counseling Center of the Azarbaijan Shahid Madani University in 1396. The participants were divided in two groups and received two different types of stimulations; anodal and sham stimulations on F3 area as well as cathode stimulation on the orbitofrontal cortex (ten 20-minute 2mA tDCS sessions). Results: The results revealed that application of tDCS through simultaneous anodal significantly improved response inhibition in patients suffering from OCD. Conclusion: The findings have shown that application of anodal tDCS can improve the response inhibition in OCD patients, possibly via enhancement of excitability in the prefrontal cortex.
