Objective Diagnostic Markers and Personalized Intervention in MDD Patients

May 18, 2016 updated by: Xin Yu, Peking University

The Establishment of the Objective Diagnostic Markers and Personalized Medical Intervention in Patients With Major Depressive Disorders (MDD)

Major depressive disorder (MDD) is one of the most common psychiatric disorders, with high recurrence rate, suicide rate and disability rate. It's reported that the global burden caused by MDD will be up to the second rank among all the disease burdens by 2020. China is also confronted with the daunting challenges against MDD. It's assessed that the monthly incidence of MDD is 6.1%, non-hospitalizing rate reaches up to 92% and the non-treatment rate is approximate 95%. However, to date, the pathogenesis of MDD is obscure and the current therapies don't work well. Therefore, it's urgent and critical to elucidate the pathogenesis of MDD, to develop early diagnostic criteria and effective intervention in MDD. Considering the diversity of weights on genetic factor and environmental factor in MDD, in this project, the investigators aim firstly to explore the effect of "genetic-environmental interaction"on the pathogeny of MDD for classifying MDD into "genetic type", "environmental type" and "others" based on a case-control study. We next conduct the neurobiological, neurocognitive and psycho-behavioral assessments among MDD, schizophrenia and healthy groups to screen the salient endophenotypes for establishing the diagnostic models of MDD . The investigators further analyse the changes of these indicators after 8 weeks'medication to select the potential predictors for therapeutic evaluations and interventional options in MDD patients. Finally, the investigators continue a 2-year follow-up study to test and verify the predictors of prognosis in MDD patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)
