Complex network analysis, based on graph theory and neuroimaging data, allows investigators to describe the large-scale brain networks using several topological characteristics. This approach overcomes the shortcoming of traditional neuroimaging research that can only focus on a few brain regions either individually or in combination. This review concluded includes the following issues: 1) the concepts of complex brain network analysis; 2) the researches of depression depressive disorder based on graph theory ; 3) weaknesses, conclusions and future directions of brain network research. Convergent evidence shows that Major Depressive Disorder (MDD) patients show small-world architecture in brain networks, but some of their nodal characteristics evolved with the development of disease, and the whole brain network tended to be a random network. Regional abnormality mainly existed within the default mode network (DMN) and prefrontal-limbic circuits. In future studies, construction of whole brain networks in cognitive tasks and Minimum Spanning Tree (MST) may provide more information about the disrupted brain connectome of MDD.
