The emotionally unstable personality disorder is a personality disorder, which is mainly characterized by a lack of impulse control. This leads to ill-considered action without consideration of the consequences, as well as to increased readiness for conflict. Two manifestations of this personality disorder are distinguished.
First, an impulsive type in which the focus is particularly on the willingness to conflict and an impulse control disorder. Secondly, the borderline type, in which after ICD -10 also numerous other symptoms must be present. Due to the clinical significance and complexity of the second disorder, this chapter mainly deals with emotionally unstable borderline personality disorder.
The term “borderline” is characterized by the multitude of symptoms, which include both psychotic and neurotic aspects. The patients’ lives are accompanied by a disturbance of the self-image, a chronic feeling of emptiness and unstable relationships. Inpatient treatment is usually due to self-destructive behavior with self-inflicted injuries (“scratches”) and suicidal acts. The multimodal therapy concept is based on psychotherapy concepts that are supported by antidepressants and antipsychotics. The dialectical behavioral therapy according to Linehan is particularly frequently used.
