- Network dynamics of depression, anxiety, sleep disturbances, and suicidal symptoms in Chinese adolescents: a longitudinal cross-sectional and cross-lagged panel network analysis (2026) · Psychological Medicine · cited 3× · doi
Traditional approaches focus on latent common factors or investigate associations between isolated symptoms and global severity, offering limited insight into how specific symptoms contribute to a heterogenous and often persistent clinical presentation. There is a need for a longitudinal network perspective on the complex dynamic relationships between depression, anxiety, sleep disturbances, and suicidal symptoms.

The abnormal patterns of functional network connectivity in late-onset depression remain unclear. The relationship between depressive symptoms and cognitive decline in late-onset depression is not well understood. There is a need to identify biomarkers for depression and cognitive decline in late-onset depression.

The relationship between sleep disturbances and major depressive disorder is bidirectional, but the neural mechanisms underlying this relationship are not fully understood. There is a need for studies investigating the association between sleep symptom burden and default mode network homogeneity in adolescents with major depressive disorder.
