Summary
Schizophrenia involves brain structure differences, including enlarged ventricles and altered cortical and subcortical regions. Prenatal factors like viral infections may interact with genetics, impacting brain development.
Area of Science:
- Neuroscience
- Psychiatry
- Neuropathology
Background:
- Neuroimaging reveals cerebral and structural variances in schizophrenia patients.
- Established findings include enlarged lateral ventricles and temporobasal cortical deficits.
Purpose of the Study:
- To investigate cerebral and structural variances in schizophrenic psychoses.
- To explore neuropathological and epidemiological evidence for etiological factors.
Main Methods:
- Neuroimaging techniques to identify structural differences.
- Neuropathological investigations of cortical and subcortical brain regions.
- Epidemiological studies examining prenatal developmental disturbances.
Main Results:
- Enlarged striatum and globus pallidus volumes in schizophrenics.
- Cytoarchitectonic disturbances in the rostral entorhinal region linked to prenatal cell migration.
- Architectonic changes in the rostral cingulate gyrus.
Conclusions:
- Schizophrenia is associated with prenatal brain development disturbances, particularly in the second trimester.
- Maternal viral infections, such as Influenza A2, during pregnancy are implicated.
- The etiology likely involves an interaction between genetic predisposition and exogenous factors.
