The incidence of schizophrenia in the western world is estimated at 15100000 population. When this kind of psychological disorder becomes active the affected person may show some strange symptoms that are not normally present in the person before.

These structural studies have been complemented by functional imaging research which has indicated that schizophrenia is particularly associated with altered function in the prefrontal cingulate and temporal cortex Reference McGuire and Matsumoto McGuire Matsumoto 2004 and that symptoms such as auditory hallucinations and thought disorder are mediated by. Similarly neuroimaging studies of cognitive remediation in schizophrenia focus differentially on structural functional and connectivity changes. Recruiting broader cortical areas to perform identical tasks.

Scientists have long tried to find out what was going wrong in the brains of people with schizophrenia but with so little success for so long that for some years the. -results consistent with brain damage and dopamine overactivity -CAT scans and MRI scans indicate much larger ventricles in schizophrenics compared to controls which suggest diffuse neuronal damage and cell loss. Summary Enlargement of ventricular size and metabolic decreases in the frontal and temporal lobes char- acterize both aging and schizophrenia.

Nancy Andreasen and her lab are using brain scans from magnetic resonance imaging to better understand how anti-psychotic drugs affect the brains of schizophrenia patients. Patients with schizophrenia have a mortality ratio of 26 against patients without schizophrenia. The lifetime prevalence of schizophrenia is 71000.

The Brain and Schizophrenia. CT scans show tightly-packed narrow surface fissuring of the schizophrenic brain. At least some patients with schizophrenia also show an accelerated course of brain-imaging changes with more rapid ventricular enlargement and frontal decreases than occur in normal controls.

Brain imaging studies of schizophrenia sufferers show that they tend to have enlarged ventricles reduction of gray matter temporal lobe shrinkage and increased myelination of white matter. The findings suggest that those who have schizophrenia are being affected by something before they show outward signs of the disease. What do brain scans of schizophrenics show.
