Default mode network changes in multiple sclerosis: a link between depression and cognitive impairment?

In multiple sclerosis (MS), depression is a common disorder whose pathophysiology is still debated. To gain insights into the pathophysiology of depression in MS, resting‐state (RS) functional connectivity (FC) changes of the default mode network (DMN), salience network (SN) and executive control network (ECN) were assessed in a group of depressed MS (D‐MS) patients and in appropriately matched control groups.
