An Updated Review of Werner Janzarik’s Psychopathological Model of Endogenous (Idiopathic) Psychoses

“Dynamische Grundkonstellationen in endogenen Psychosen” is Werner Janzarik’s most influential work. It is aimed at defining an unitary psychopathological model of endogenous psychoses independently from categorical nosology. His main contribution is the distinction between dynamic (the whole of emotions, impulses and intentions) and structure (the whole of psychic contents which remain stable throughout the course of life), whose intersection is well elicitable both in organic and in endogenous psychoses. Janzarik describes different types of dynamic alterations (dynamic constellations) in the different stages of the psychotic course: dynamic reduction in depressive phases, dynamic expansion in manic states, instability and depletion in the different clinical phases of long-term schizophrenic psychoses. Janzarik’s work is nowadays completely forgotten. In the paper the Authors resume his main clinical ideas on major mental illnesses, because they fit well with long term courses of psychoses as observable in mental health public services, in an era of serious crisis of categorical distinctions. Janzark supports a dynamic model of psychoses, characterized by different stages and switchovers between different psychotic categories over time. In addition, this model could be used in standardized pharmacological trials to define which treatments are really effective in the different “dynamic” alterations of both affective and schizophrenic psychotic courses.
