    49. Causes of Schizophrenia • Brain Structure/ Frontal Lobes: • Chronic schizophrenics may have smaller frontal lobes • PET scans show reduced frontal lobe function and decreased metabolism in schizophrenics • Brain Ventricles: • seem to be larger in schizophrenics than in other people • ventricles on left side tend to be larger than those on the right • large brain ventricles suggest deterioration or atrophy of brain tissue
