Default mode network abnormalities in bipolar disorder and schizophrenia.
The default-mode network (DMN) consists of a set of brain areas preferentially activated during internally focused tasks. We used functional magnetic resonance imaging (fMRI) to study the DMN in bipolar mania and acute schizophrenia. Participants comprised 17 patients with bipolar disorder (BD), 14 patients with schizophrenia (SZ) and 15 normal controls (NC), who underwent 10-min resting fMRI s...
متن کاملPatterns of Default Mode Network Deactivation in Obsessive Compulsive Disorder
The objective of the present study was to research the patterns of Default Mode Network (DMN) deactivation in Obsessive Compulsive Disorder (OCD) in the transition between a resting and a non-rest emotional condition. Twenty-seven participants, 15 diagnosed with OCD and 12 healthy controls (HC), underwent a functional neuroimaging paradigm in which DMN brain activation in a resting condition wa...
متن کاملDefault mode network subsystem alterations in obsessive-compulsive disorder.
BACKGROUND Although neurobiological models of obsessive-compulsive disorder (OCD) traditionally emphasise the central role of corticostriatal brain regions, studies of default mode network integrity have garnered increasing interest, but have produced conflicting results. AIMS To resolve these discrepant findings by examining the integrity of default mode network subsystems in OCD. METHOD C...
متن کاملDefault-Mode Network Abnormalities in Pediatric Posttraumatic Stress Disorder.
OBJECTIVE Resting-state functional magnetic resonance imaging (rs-fMRI) studies of adult posttraumatic stress disorder (PTSD) have identified default-mode network (DMN) abnormalities, including reduced within-network connectivity and reduced anticorrelation between the DMN and task-positive network (TPN). However, no prior studies have specifically examined DMN connectivity in pediatric PTSD, w...
متن کاملDissociation of Regional Activity in Default Mode Network in Medication-Naive, First-Episode Somatization Disorder
BACKGROUND Patients with somatization disorder (SD) have altered neural activity in the brain regions of the default mode network (DMN). However, the regional alteration of the DMN in SD remains unknown. The present study was designed to investigate the regional alterations of the DMN in patients with SD at rest. METHODS Twenty-five first-episode, medication-naive patients with SD and 28 age-...
