Clinical Trial Summary

This study is designed to find Electroencephalogram (EEG) biomarkers to predict transcranial direct current stimulation (tDCS) response in obsessive-compulsive disorder.


Clinical Trial Description

The purpose of this study is to explore resting state electroencephalography and transcranial magnetic stimulation and electroencephalography (TMS-EEG) biomarkers that would predict transcranial direct current stimulation (tDCS) response in obsessive-compulsive disorder with cathode electrode targeting orbitofrontal cortex (OFC). 30 OCD patients will be recruited to this study and performed once a day, five times a week direct current stimulation treatment for two weeks. The investigators will assess symptom severity before and after two weeks of tDCS. Through the study, Yale-Brown Obsessive Compulsive Scale(Y-BOCS), the Obsessive Compulsive Inventory-Revised (OCI-R), the Beck Depression Inventory(BDI), Pittsburgh sleep quality index (PSQI)and side-effect questionnaire will be obtained by a trained investigator. Resting state electroencephalography and TMS-EEG testing will be conducted before and after tDCS treatment. ;
