Alterations of static and dynamic functional connectivity in adolescents with first-episode major depression and suicidal tendencies

This study used graph theory-based dynamic and static functional connectivity strength (FCS) approaches to investigate the differences in global brain connectivity patterns in depressed adolescents with and without suicide attempts. Our findings suggest that abnormal connectivity patterns in multiple brain regions involving cognition and emotion control, and self-referential processing are associated with the increasing risk of vulnerability to a suicide attempt in depressed adolescents.
