Changes of brain default mode network in adolescents' emotion disorder / 中华行为医学与脑科学杂志

ABSTRACT

The incidence of emotion disability-related diseases in adolescents is increasing year by year, causing great harm to their physical and mental health, even affecting them until adulthood. However, the mechanism of this has not been fully clarified. The default mode network is a brain network composed of brain regions that are still active in the resting state. DMN is a hot pot in the field of resting state brain function research, but few studies have focused on its pathological changes in the adolescents with emotion disability-related diseases. In recent years, a number of articles related to adolescent emotion disorders have provided clues for understanding the characteristics and potential mechanisms of adolescent emotion disorders from the perspective of imaging. This paper summarized the related research over the years and found that the occurrence of emotion disorders is closely related to the activation of the default mode network brain regions, cortical thickness, gray matter volume or density, and changes in functional connections between brain areas.Some changes in brain structure and function can be used as predictive factors. In this paper, by summarizing the changes in brain imaging of these emotion disorders, we hope to explore new neuroimaging landmark changes, which can provide theoretical basis for the prevention, diagnosis and treatment of emotion disorders related diseases in adolescents.
