[Borderline disorder and schizophrenia. Still a diagnostic problem]

Abstract

Two case-reports highlight the problems of co-morbidity of schizophrenia and borderline disorder. On the other hand, borderline disorder in schizophrenia can represent a pre-existent, lasting personality disorder, on the other hand it can be temporary syndrome in the course of illness. The assumption that a borderline syndrome can be a recompensation stage in the course of schizophrenia seems evident by clinical and psychodynamic points of view (concerning a coping strategy). The present categories of DSM III-R and ICD-10, however, do not allow an adequate diagnostic classification of this syndrome.
