[Clinical and therapeutic approach of the borderline patient in psychiatric clinic (author's transl)].

The author summarises the evolution of the borderline concept in the literature. He emphasizes the specificity of the pathological objectal relation and the lack of development of the ego in the separation-individualisation phase. The clinical approach of the borderline patient shows the lability of interpersonal relations of the borderline patient and the presence of a variable and polymorphic symptomatology. The author gives some considerations which are essential in undertaking a treatment with the borderline patient during a brief hospitalisation in a psychiatric service. This type of treatment is based on an early clinical diagnosis, a homogenous, logical and adequate attitude of the therapeutic team, the organisation of an adequate therapeutic team where the patient can learn to accept his own pathological findings and the initiation of an individual psychotherapy.
