Research on the Biological Mechanism of the Efficacy of Psychotherapy for Depression Based on the fNIRS

Depressive Disorder Clinical Trial

Official title:
Research on the Biological Mechanism of the Efficacy of Psychotherapy for Depression Based on the Near-Infrared Functional Imaging System (fNIRS)

Clinical Trial Summary

In this project, the investigators will implement medication therapy, psychotherapy, and a combination of medication therapy with psychotherapy, specifically utilizing IPT, in patients with depression. Simultaneously, the investigators will conduct comprehensive fNIRS assessments on all patients to evaluate changes in their brain function and determine the level of effectiveness of psychotherapy. The investigators will also employ standardized psychological assessments to evaluate patients, allowing for a comparison of the effectiveness of fNIRS assessments and providing clarity on the efficacy of psychotherapy in patients with depression, as the investigatorsll as the differential efficacy of different treatment approaches, and establishing the biological markers of psychotherapy. Additionally, the investigators will collect blood samples, cranial magnetic resonance images, and electroencephalograms from patients before and after treatment, which will contribute to further exploration of treatment mechanisms in the future.

Clinical Trial Description

This study utilizes the Near-Infrared Functional Imaging System (fNIRS) as a biological marker for psychotherapy. The investigators propose the following scientific hypothesis: In patients with depression, levels of oxygenated hemoglobin and deoxygenated hemoglobin in different brain regions may fluctuate at different stages of the disease progression and treatment, along with changes in the activation levels of different brain regions. Neuroimaging studies on the neurobiological mechanisms of depression suggest a reduction in gray matter volume in emotion processing areas such as the limbic system, hippocampus, anterior cingulate cortex, dorsolateral prefrontal cortex, and basal ganglia. Previous neuroimaging studies have found that successful cognitive-behavioral therapy (CBT) accompanied changes in gray matter volume in the brain, as observed through fMRI. Interpersonal Psychotherapy (IPT), which is a component of the third wave of CBT, is expected to exhibit more significant expression in cognitive task-based fNIRS during IPT treatment for depression. In this project, the investigators will implement medication therapy, psychotherapy, and a combination of medication therapy with psychotherapy, specifically utilizing IPT, in patients with depression. Simultaneously, the investigators will conduct comprehensive fNIRS assessments on all patients to evaluate changes in their brain function and determine the level of effectiveness of psychotherapy. The investigators will also employ standardized psychological assessments to evaluate patients, allowing for a comparison of the effectiveness of fNIRS assessments and providing clarity on the efficacy of psychotherapy in patients with depression, as the investigatorsll as the differential efficacy of different treatment approaches, and establishing the biological markers of psychotherapy. Additionally, the investigators will collect blood samples, cranial magnetic resonance images, and electroencephalograms from patients before and after treatment, which will contribute to further exploration of treatment mechanisms in the future. ;
