Reduced left angular gyrus volume in first-episode schizophrenia.
OBJECTIVE Research suggests that the normal left-greater-than-right angular gyrus volume asymmetry is reversed in chronic schizophrenia. The authors examined whether angular gyrus volume and asymmetry were abnormal in patients with first-episode schizophrenia. METHOD Magnetic resonance imaging scans were obtained from 14 inpatients at their first hospitalization for psychosis and 14 normal co...
متن کاملHippocampal and superior temporal gyrus volume in first-episode schizophrenia.
T he article by Velakoulis et al 1 reported the important finding of hippocampal volume reduction in first-episode schizophrenia and interpreted it as evidence in support of a neurodevelopmental model of this disorder. The authors stated that " no [pre-vious] studies have examined the specificity of this finding to first-episode schizophrenia, compared with first-episode affective psychosis. " ...
متن کاملProgressive decrease of left superior temporal gyrus gray matter volume in patients with first-episode schizophrenia.
OBJECTIVE Smaller temporal lobe cortical gray matter volumes, including the left superior temporal gyrus, have been reported in magnetic resonance imaging (MRI) studies of patients with chronic schizophrenia and, more recently, in patients with first-episode schizophrenia. However, it remains unknown whether there are progressive decreases in temporal lobe cortical gray matter volumes in patien...
متن کاملReduced cortical inhibition in first-episode schizophrenia.
Disturbances in cortico-cortical and cortico-subcortical circuits in schizophrenia have been described by previous neuroimaging and electrophysiological studies. Transcranial magnetic stimulation (TMS) provides a neurophysiological technique for the measurement of cortical excitability, especially of the motoneural system. Previous studies using paired-pulse TMS to investigate short-interval co...
متن کاملReduced cortical thickness in first episode schizophrenia.
OBJECTIVE Previous morphometric studies are suggesting altered cortical thickness mainly in prefronto-temporal regions in first episode schizophrenia. In an extension of these earlier studies, we used an entire cortex vertex-wise approach and an automated clustering for the detection and exact quantification of cortical thickness alterations in first episode schizophrenia. METHODS A group of ...
