Treatment Response Biomarkers in MDD

More specifically, the goals of this study are to 1) explore the potential biomarkers for Major Depressive Disorder by comparing MDD patients and healthy controls; 2) investigate the biochemical indicators for subtypes of MDD through long-term cohort follow-up studies; 3) investigate the differences and similarities among different types of MDD patients in terms of cognitive functions, biological tests, as well as neuroimaging data; 4) evaluate and analyze the prognosis of patients according to the baseline level, and search for the biomarkers regarding MDD treatment response to guide the clinical treatment and intervention of patients with MDD; 5) Through the long-term follow-up study, the behavioural and biochemical indicators of the patients with MDD were collected, the differences between the indicators before and after remission were examined, and the state and quality of the pathophysiological indicators of the patients with MDD were investigated.
