[Psychopathology and treatment of borderline personality disorder].

Borderline personality disorder (BPD) is a severe psychiatric disorder accounting for about 30% of the total cost for psychiatric inpatient care in the Federal Republic of Germany. Suicidality, self-harm, and severe deterioration of self-esteem lead to chronic suffering for patients and the social environment. With a prevalence rate of 1.5%, BPD is more frequent than schizophrenic disorders. Within the last years, empirically based knowledge concerning the psychopathology, etiopathogenesis, and treatment of BPD have significantly improved. Today most researchers postulate pervasive affective dysregulation at the core of borderline symptomatology and see it as the consequence of an interplay between genetic vulnerability, sociobiographic experience, and dysfunctional behavior. Disorder-specific psychotherapeutic treatments, especially dialectical behavior therapy, show significant improvements in both in- and outpatient settings. Studies on psychopharmacological treatment with promising results have also recently been published. Sufficient outpatient treatment by trained psychotherapists is underdeveloped. Hence, specialized inpatient centers assume this task.
