Overview
Brief Summary
The purpose of this study is to assess the feasibility and efficacy of real-time fMRI neurofeedback for rumination.
Detailed Description
Neuroimaging MRI techniques for measuring brain structure, tissue composition, and Blood Oxygenation Level Dependent functional Magnetic Resonance imaging (BOLD fMRI) will be used to measure task-dependent and task-independent brain hemodynamic and electrophysiological changes in human subjects with major depressive disorders (MDD). After being informed about the study and potential risks, all participants giving written informed consent will undergo one session of the cognitive process-based fMRI neurofeedback (CNF) targeting the rumination-related brain functional connectivity, and a one-week follow-up. Participants will be randomized in a double-blind manner (participant and investigator) in a 1:1 ratio to Active (receiving feedback from their own brain activity) or Sham (receiving artificially generated feedback).

Outcomes
Primary Outcomes
Changes in Brooding subscale of Ruminative Responses Scale (RRS) scores
Time Frame: Through study completion (average: 2 weeks)
The RRS Brooding subscale is a self-report scale to measure brooding ruminative responses. A higher score indicates higher brooding ruminative responses with a maximum score of 20 and a minimum score of 5.
Functional connectivity change between precuneus and right temporoparietal junction (rTPJ)
Time Frame: Through study completion (average: 2 weeks)
Functional connectivity between precuneus and rTPJ will be calculated and evaluated using fMRI BOLD percent signal change.
Secondary Outcomes
- Changes in sum of Brooding and Depression subscales of Ruminative Responses Scale (RRS) scores(Through study completion (average: 2 weeks))
- Changes in total score of Ruminative Responses Scale (RRS) scores(Through study completion (average: 2 weeks))
- Changes in Depression subscale of Ruminative Responses Scale (RRS) scores(Through study completion (average: 2 weeks))
- Changes in Reflection subscale of Ruminative Responses Scale (RRS) scores(Through study completion (average: 2 weeks))
