Default Mode Network in Post-stroke Depression

Default 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...

Default mode network mechanisms of transcranial magnetic stimulation in depression.

BACKGROUND Repetitive transcranial magnetic stimulation (TMS) of the dorsolateral prefrontal cortex (DLPFC) is an established treatment for depression, but its underlying mechanism of action remains unknown. Abnormalities in two large-scale neuronal networks-the frontoparietal central executive network (CEN) and the medial prefrontal-medial parietal default mode network (DMN)-are consistent fin...

The default mode network and self-referential processes in depression.

The recently discovered default mode network (DMN) is a group of areas in the human brain characterized, collectively, by functions of a self-referential nature. In normal individuals, activity in the DMN is reduced during nonself-referential goal-directed tasks, in keeping with the folk-psychological notion of losing one's self in one's work. Imaging and anatomical studies in major depression ...

Anxiety and Depression Symptoms in Post Stroke Outpatients

Abstract Introduction: Given the high prevalence of stroke, it seems necessary to investigate and identify the factors that increase morbidity and mortality following stroke. Among these factors are mental disorders after stroke which lead to increased morbidity and mortality, independently of other risk factors and the severity of the disease. Objective: To investigate the frequency of depre...
