Abstract:

Depressive rumination is the focused attention on the symptoms of one's distress, and on its possible causes and consequences, as opposed to its solutions. It is characterized by excessive concern about negative affect, deficits in cognitive control and maladaptive self-reference process. Based on these cognitive characteristics, recent fMRI evidence showed that the neural mechanisms of depressive rumination were associated with amygdale, prefrontal cortex (PFC) and default mode network (DMN). Future studies should focus on the brain region mediating subtype of depressive rumination, gene, as well as providing useful interventions.

Key words: depressive rumination, cognitive mechanism, neural mechanism
