Shape differences in the corpus callosum in first-episode schizophrenia and first-episode psychotic affective disorder.
OBJECTIVE The corpus callosum, the largest white matter tract in the brain, is a midline structure associated with the formation of the hippocampus, septum pellucidum, and cingulate cortex, which have been implicated in the pathogenesis of schizophrenia. Corpus callosum shape deformation, therefore, may reflect a midline neurodevelopmental abnormality. METHOD Corpus callosum area and shape we...
متن کاملAbnormalities of the corpus callosum in first episode, treatment naive schizophrenia.
BACKGROUND Structural alterations in the association cortices as well as in the corpus callosum (CC) have been described in schizophrenia, and have been considered to reflect developmental abnormalities. Areas of primary and association cortices have been topographically mapped in the CC. OBJECTIVE To investigate whether, in schizophrenia, there are alterations in CC subdivisions that connect...
متن کاملCorpus callosum in first-episode patients with schizophrenia--a magnetic resonance imaging study.
BACKGROUND Morphometric studies on the corpus callosum (CC) in schizophrenia have yielded contradictory results. The aim of the present study was to investigate magnetic resonance imaging (MRI) abnormalities of the CC in first-episode patients with schizophrenic psychoses. METHOD We assessed volumetric MRI in 31 patients with diagnoses of schizophrenia, schizophreniform or schizoaffective dis...
متن کاملMorphology of the corpus callosum at different stages of schizophrenia: cross-sectional study in first-episode and chronic illness.
BACKGROUND The shape of the corpus callosum may differ in schizophrenia, although no study has compared first-episode with established illness. AIMS To investigate the size and shape of the corpus callosum in a large sample of people with first-episode and established schizophrenia. METHOD Callosal size and shape were determined using high-resolution magnetic resonance imaging on 76 patient...
متن کاملFractional Anisotropic Changes of Corpus Callosum Associated with Antipsychotic Treatment in First-Episode Antipsychotic Drug-Naive Patients with Schizophrenia
Fractional anisotropic changes of corpus callosum associated with antipsychotic treatment in first-episode antipsychotic drug-naive patients with schizophrenia Objective: Schizophrenia involves white matter abnormalities that might have a central role in the pathophysiology. Abnormal brain connectivity especially in prefrontal and temporal heteromodal cortex has been suggested as the leading st...
