The model of unitary psychosis as a basis for understanding affective processes in psychoses.

Nosological questions in psychiatry imply core questions of understanding and interpretation in the field of mental illness. The model of unitary psychosis in contrast to the hypothesis of nosological entities has been discussed in controversial terms for a long time. This history of psychiatry in review of a hundred years' development of psychopathology, neurobiological sources and psychosociological conditions points out the multiplicity of adaptive processes in a multifactorial-multiconditional way. Nosological entities such as formulated by Leonhard would have a promising interpretation in the framework of a unitary approach in the philosophy by Rennert and the analysis of various psychodynamic axes.
