چکیده
Major depressive disorder (MDD) is associated with alterations in multiple brain networks including the default mode network (DMN). The DMN is a set of large-scale connected brain regions that oscillate synchronously and are more active during rest relative to goal-directed tasks. Several functions have been hypothesized for the DMN, including cognitive, self-referential and social functions. Widespread alterations in the core and the subsystems of the DMN as well as in their interplay have been reported in MDD. We will review the evidence supporting DMN alterations in patients with MDD and underscore how they can contribute to social and affective cognitive impairments

Imbalance of default mode and regulatory networks during externally focused processing in depression.
Attentional control difficulties likely underlie rumination, a core cognitive vulnerability in major depressive disorder (MDD). Abnormalities in the default mode, executive and salience networks are implicated in both rumination and attentional control difficulties in MDD. In the current study, individuals with MDD (n = 16) and healthy controls (n = 16) completed tasks designed to elicit self-f...
متن کاملAltered Cerebellar-Cerebral Functional Connectivity in Geriatric Depression
Although volumetric and activation changes in the cerebellum have frequently been reported in studies on major depression, its role in the neural mechanism of depression remains unclear. To understand how the cerebellum may relate to affective and cognitive dysfunction in depression, we investigated the resting-state functional connectivity between cerebellar regions and the cerebral cortex in ...
متن کاملImagination in human social cognition, autism, and psychotic-affective conditions.
Complex human social cognition has evolved in concert with risks for psychiatric disorders. Recently, autism and psychotic-affective conditions (mainly schizophrenia, bipolar disorder, and depression) have been posited as psychological 'opposites' with regard to social-cognitive phenotypes. Imagination, considered as 'forming new ideas, mental images, or concepts', represents a central facet of...
متن کاملStructural and Functional Connectivity of Default Mode Network underlying the Cognitive Impairment in Late-onset Depression
To identify the association between the functional and structural changes of default mode network (DMN) underlying the cognitive impairment in Late-onset depression (LOD), 32 LOD patients and 39 normal controls were recruited and underwent resting-state fMRI, DTI scans, and cognitive assessments. Seed-based correlation analysis was conducted to explore the functional connectivity (FC) of the DM...
متن کاملDefault Mode Network Connectivity in Stroke Patients
The pathophysiology of episodic memory dysfunction after infarction is not completely understood. It has been suggested that infarctions located anywhere in the brain can induce widespread effects causing disruption of functional networks of the cortical regions. The default mode network, which includes the medial temporal lobe, is a functional network that is associated with episodic memory pr...
