Historically, the Wernicke-Kleist-Leonhard School represents a countermovement to psychopathology as described by Karl Jaspers and Kurt Schneider. The School aimed to interlink psychopathological and neurobiological aspects. Starting from the model of different functional neuronal systems, each of which can be disturbed in the sense of a hypofunction, hyperfunction, or parafunction, it developed a comprehensive phenomenology of psychopathological symptoms and syndromes that finally culminated in Karl Leonhard's course descriptions. This school of thought can provide important impulses even today. Thus, on the one hand, the neurobiological models can serve as the basis for additional research projects and on the other hand, the psychopathological descriptions of disorders can perhaps also be interpreted in the sense of typological constructs that can contribute to pragmatic clinical decisionmaking.
