Pathways between early visual processing and functional outcome in schizophrenia.
BACKGROUND Early visual processing deficits are reliably detected in schizophrenia and show relationships to poor real-world functioning. However, the nature of this relationship is complex. Theoretical models and recent studies using statistical modeling approaches suggest that multiple intervening factors are involved. We previously reported that a direct and significant association between v...
متن کاملBiosocial pathways to functional outcome in schizophrenia.
UNLABELLED Biosocial models are preeminent in the study of schizophrenia, yet there has been little empirical testing of these models. OBJECTIVE This study provided the first test of a biosocial causal model of functional outcome in schizophrenia, using neurocognition, social cognition, social competence and social support as predictors of both global and specific domains of functional outcom...
متن کاملReduction of Interhemispheric Functional Connectivity in Sensorimotor and Visual Information Processing Pathways in Schizophrenia
BACKGROUND Previous studies have demonstrated interhemispheric functional connectivity alterations in schizophrenia. However, the relationship between these alterations and the disease state of schizophrenia is largely unknown. Therefore, we aimed to investigate this relationship using voxel-mirrored homotopic connectivity (VMHC) method. METHODS This study enrolled 36 schizophrenia patients w...
متن کاملEarly-stage visual processing and cortical amplification deficits in schizophrenia.
BACKGROUND Patients with schizophrenia show deficits in early-stage visual processing, potentially reflecting dysfunction of the magnocellular visual pathway. The magnocellular system operates normally in a nonlinear amplification mode mediated by glutamatergic (N-methyl-D-aspartate) receptors. Investigating magnocellular dysfunction in schizophrenia therefore permits evaluation of underlying e...
متن کاملProcessing speed mediates the relationship between verbal memory, verbal fluency, and functional outcome in chronic schizophrenia.
Verbal fluency and verbal memory have been reported to be diminished in patients with schizophrenia. These deficits could partially predict functional disability in this pathology. However, processing speed often mediates the relationship among cognitive processes in the disorder. Our goal was to analyse the influence of processing speed as mediator of the relation between verbal fluency-verbal...
