The subcortex, frontal lobes, and psychosis.
Goldberg (1985) has argued that disruption of the mesolimbic/ mesocortical dopamine system by long-term neuroleptic treatment may be responsible for producing the tardive dysmentia syndrome (Wilson et al. 1983), which can be seen as similar to the pseudopsychopathic presentation sometimes observed following damage to orbitomedial frontal cortex (Blumer and Benson 1975; Damasio 1979). Similarly,...
متن کاملCerebello-thalamo-cortical networks predict positive symptom progression in individuals at ultra-high risk for psychosis
Prospective longitudinal evaluation of adolescents at ultra-high-risk (UHR) for the development of psychosis enables an enriched neurodevelopmental perspective of disease progression in the absence of many of the factors that typically confound research with formally psychotic patients (antipsychotic medications, drug/alcohol dependence). The cerebellum has been linked to cognitive dysfunction ...
متن کاملThalamo-frontal white matter alterations in chronic schizophrenia: a quantitative diffusion tractography study.
Diffusion tensor imaging (DTI) and fiber tractography are useful tools for reconstructing white matter tracts (WMT) in the brain. Previous tractography studies have sought to segment reconstructed WMT into anatomical structures using several approaches, but quantification has been limited to extracting mean values of diffusion indices. Delineating WMT in schizophrenia is of particular interest ...

متن کاملThalamo-frontal connectivity mediates top-down cognitive functions in disorders of consciousness.
OBJECTIVE We employed functional MRI (fMRI) to assess whether (1) patients with disorders of consciousness (DOC) retain the ability to willfully engage in top-down processing and (2) what neurophysiologic factors distinguish patients who can demonstrate this ability from patients who cannot. METHODS Sixteen volunteers, 8 patients in vegetative state (VS), 16 minimally conscious patients (MCS)...
