[Psychopathology of organic psychoses with reference to differential diagnostic, epidemiologic and morphologic aspects].

Following a brief discussion of the historical development of the term "Organic Psychosis", detailed consideration is given to the phenomenology and differential diagnosis of this group of diseases. The published epidemiological data is compared to the results of our own study. The cranial CT makes it possible to correlate clinical and morphological findings. In our investigation 72.5% of the patients with severe chronic organic psychosis show considerable brain atrophy. The morphological aspect is a determining factor for the therapeutic measures and for the prognosis.
