Establish a Specific Cohort Database for Depressive Disorders

Depression is characterized by high prevalence, high recurrence rate, high disability rate, high suicide rate, and heavy disease burden. However, the diagnosis, treatment, and prognosis of depression are difficult to meet the clinical needs at present. This study plans to integrate a large sample of hospital clinical data, laboratory examination data, brain imaging, and electrophysiological data, as well as audio-visual data, to establish a database for depressive disorder, and long-term follow-up to form a specific disease cohort. This study will provide a scientific basis for exploring biomarkers related to objective diagnosis and treatment of depression.
