PDs impinge on medical practice in multiple ways, including self-destructive behaviors, interpersonal disturbances, and nonadherence. Appropriate physician responses and effective treatments exist for many PDs. Correct diagnosis and proper intervention will help to improve patient outcomes. Borderline personality disorder (BPD) is an extremely debilitating disorder that can significantly interfere with the physician-patient relationship. BPD will receive extra focus in several sections of this chapter.
