Inadequate response to available pharmacological and psychotherapeutic interventions is common in OCD. Adjunctive brain stimulation methods to address the inadequate treatment response in OCD have found a special interest in research. This study aimed to examine the efficacy of adjunctive deep transcranial magnetic stimulation (dTMS) in ameliorating the symptoms of OCD and the effect of dTMS on activation of brain regions while performing the Stroop task using functional magnetic resonance imaging (fMRI).<\/jats:p><\/jats:sec><jats:sec id=\"S1092852922000803_sec2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>A total of 41 patients were assessed for the study out of which 15 OCD patients received 10 sessions of high-frequency dTMS using the H7 coil to target the anterior cingulate cortex and the medial prefrontal cortex over a period of 2\u00a0weeks. The Yale-Brown Obsessive-Compulsive Scale, the Hamilton Anxiety Rating Scale, and the Hamilton Depression Rating Scale were used for the pre- and post-stimulation clinical assessment. fMRI was used to measure the activation of brain regions while performing the Stroop task.<\/jats:p><\/jats:sec><jats:sec id=\"S1092852922000803_sec3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>There was a significant improvement in the obsessive-compulsive, anxiety, and depressive symptoms after the 2\u00a0weeks of the dTMS treatment.
