Establish a Specific Cohort Database for Depressive Disorders

Construct the structured data set for depression by integrating a large sample of outpatient and inpatient clinical data, blood tests, psychological tests, and brain imaging data.

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.
