[Dissociation and schizophrenia. Schizophrenias--a dissociative nosopoietic construct?].

The historical roots of the nosopoietic construct schizophrenia are traced: the nosographic construction by Kraepelin, an act of unification and split at the same time. The name schizophrenia reflects the tradition of the model of dissociation which is aetiologically connected with the idea of weakness of the synthetic power of the psyche: psychasthenia. In the establishment of the supposed nosological entity schizophrenia, the name-giving idea of dissociation was almost forgotten. Thus, nowadays Dissociative Disorders are classified in ICD and DSM separately from schizophrenic disorders, but it must be borne in mind that the schizophrenic disorders represent the most severe of disorders, hypothetically based on dissociation, namely, fragmentation of the ego.
