[Diagnosis of the borderline disorder].

A typical borderline case is presented, "borderline" being conceptualized as a form of personality disorder/psychopathy. The main characteristics have turned out to be 1. diversity and variability of symptoms, 2. affective disturbances and insufficient impulse control, 3. disturbed interpersonal relations, 4. pronounced suffering compelling the patient to seek treatment. The necessity of standardizing conceptions and characteristics of borderline disorders is being stressed and reporting on prototype cases considered an expedient measure to this effect.
