[Consideration of schizophrenia from a unitary point of view].

The paper deals with the nozological concept of a universal genesis of psychoses which claims that psychotic syndromes are multiveariable and are related to biological, genetical, social and situation factors. The different types of syndromes are not consistent in repeated psychoses and cannot be considered characteristic only of certain historical psychotic patterns. A new way for the exploration of pathogenetical and psychopathological aspects of psychoses is the identification of syndromes by means of the effects of psychopharmacological drugs.
