Du mind-wandering à la rumination dans la dépression : aspects physiopathologiques et pistes de prévention

Abstract : We first describe the links between mind-wandering (MW), rumination and depression (MDD). MW is a common and frequent phenomenon, when our thoughts are not directed to what we are doing. When MW becomes less flexible and the thoughts more negative and repetitive, it becomes rumination. This latter is a major risk factor and a key prognostic symptom of depressive disorder. MW and rumination are targets for new therapies like mindfulness based cognitive therapy, and can be targeted by the new neuromodulation tools. We then report methods and results of a behavioral study conducted to explore MW differences between dyshporic subjects and controls. Subjects passed a monotonous vigilance task in order to generate and evaluate their MW. Our results have highlighted a greater focus of dysphoric subjects on their MW as well as an increased variability in the allocation of their attentional resources. We discuss the interpretation of our results, and specifically the weight of meta-cognition in the effect of MW.
