[0002] Depression is a common and serious psychological disorder, and its incidence rate is increasing year by year, which has brought a heavy burden to society and individuals. Traditional methods of diagnosis and treatment of depression mainly rely on subjective questionnaires, doctors' experience judgments and drug treatments, which have many limitations. First, subjective questionnaires and doctors' experience judgments are often affected by patients' subjective feelings, doctors' personal experience and prejudice, resulting in inaccurate diagnostic results. Secondly, although drug treatment can relieve symptoms to a certain extent, it lacks personalization and cannot provide precise treatment for the specific conditions of different patients, and there may be problems such as side effects and drug resistance.

[0003] In addition, patients are often reluctant to seek medical treatment due to "stigma" and privacy concerns, which further exacerbates the problem of delayed treatment. At the same time, existing depression diagnosis and treatment technologies are still single-minded and non-quantitative in terms of perception and diagnostic methods, and cannot fully utilize multi-source information to comprehensively assess the patient's condition.

[0004] With the rapid development of technologies such as artificial intelligence, big data, and the Internet of Things, new ideas and methods have been provided for the diagnosis and treatment of depression. How to apply these advanced technologies to the diagnosis and treatment of depression, improve diagnostic accuracy, achieve personalized treatment, and provide comprehensive patient support has become an urgent problem to be solved.
