[The notion of psychopathological proportion and diagnostic progress in schizophrenia].

The concept of psychopathological proportions which has been described on the grounds of the analysis of the selectivity and bipolarity phenomenon, facilitates perceiving and describing clinical features of schizophrenia. The proportions make one pay closer attention to important features opposing the leading features of schizophrenia, that are not always being taken into consideration. The results of the research have verified the autistic and syntonic schizophrenia hypothesis. It may be possible that the serious and numerous differences in the results of studies on schizophrenia held by various authors are partly caused by not regarding the distinction between the syntonic and the autistic form of this psychosis.
