[Structural dynamics and vulnerability models].

Abstract

This paper links Janzarik's structural-dynamic coherence model with Zubin and Springs' vulnerability model and shows that Janzarik's model enables reduction of the multiple and partially speculative single factors of the vulnerability model to a functionally interpretable and coherent theory. We will then review the internal logic of the structural-dynamic coherence model concerning the explanatory power of pathogenetic models of schizophrenia and show that Janzarik is confirmed by the literature in the assumption that primary hypodynamism is present in the run-up to the schizophrenic prodrome and first manifestations. Structural dynamic derailment as a core phenomenon in psychotic disorders is also accepted and confirmed by the literature. On the other hand, the 'einheitspsychose', or unitary psychosis, basis of the structural dynamic model is controversial. In this context the author discusses his own Vienna school's Axes model, which suggests a variety of further determinants of the pathoplastic formation of the idiopathic psychosyndrome above and beyond Janzarik's model. Finally we discuss further questions which may arise out of the structural dynamic model.
