rTMS-tACS Stimulation on Improving Cognitive Function in Bipolar Disorder

Not Applicable

Recruiting

• Conditions: Bipolar Disorder in Remission

• Registration Number: NCT05964777
• Lead Sponsor: First Affiliated Hospital of Zhejiang University

Brief Summary

Based on the individualized positioning technology of diffusion tensor imaging (DTI), the purpose of this study is to explore a new stimulation target and protocol for the treatment of bipolar disorder in remission through the repetitive transcranial magnetic stimulation(rTMS) and transcranial alternating current stimulation（tACS）under neuronavigation，verify whether there is abnormal functional connectivity and structural connections between the dorsolateral prefrontal cortex (dlpfc) and the dorsal anterior cingulate gyrus (dacc) related to cognitive impairment in bipolar disorder in remission, which will contribute to further understand the relevant neural pathway and mechanism.
