[Pathophysiologic aspects of schizophrenic psychoses--a review]

The aim of research in the field of "Biological Psychiatry" is the phenomenological description of several aspects of psychiatric diseases and the exploration of their pathological mechanisms. The most used methods are biochemical, morphological, genetical, social psychiatric, neuro- and psychophysiological ones. From the pathophysiological view the most discussed hypothesis is that of a disturbed central information processing. In this paper a short introduction should be given on psychosocial influence on the development of psychotic symptomatology and on the periphere vegetative and electroencephalographic parameters in psychiatric patients.
