Neuroimaging has enabled us to address questions about the timing and origin of brain abnormalities in schizophrenia. First episode and longitudinal computed tomography (CT) and magnetic resonance imaging (MRI) studies of schizophrenic patients have shown that the brain abnormalities are present at onset of psychosis and are non-progressive. Such findings support the idea that schizophrenia is a developmental rather than a degenerative condition. Furthermore, the presence of ventriculomegaly and diminished hemispheric asymmetry in familial schizophrenics and in those of their relatives who appear to be transmitting the disorder, implies involvement of the genes controlling neurodevelopment. ..View full abstract
