Schizophrenia is usually viewed as a functional psychosis, a label which implies that the symptoms arise from the disorderly activity of neurons without accompanying anatomical and pathological alterations of brain structure. This view is due to the failure of pathologists to find convincing pathological changes associated with the disease in the first seven decades of the century. Over the last ten years things have changed considerably. Recent CT and MRI scan, and also postmortem studies show that various brain areas of schizophrenic patients are altered. HISTORY The two key people in the history of Schizophrenia were Emil Kraepelin and Eugene Blealer. Kraepelin organized the seriously mentally ill patients by three diagnostic groups: dementia praecox, manic depressive psychosis, and paranoia. Kraeplin?s description of dementia praecox emphasize a chronic deteriorating course, in addition to including such clinical phenomena as hallucinations and delusions.
