Exploring the Relationship Between Prolonged Grief and Borderline Personality Symptoms.

Background: Prolonged grief disorder (PGD) is a new diagnosis that is often mistaken for other psychopathologies. We report a case of PGD in a patient who screened positive for personality disorder. Both PGD and personality disorder symptoms were much improved after a course of prolonged grief disorder therapy.

Case presentation: A bereaved woman in her mid-20s sought treatment for depression 9 months after the death of her father. Her depressive symptoms responded well to antidepressant medication and a brief course of interpersonal psychotherapy. However, prolonged grief symptoms persisted at a clinically significant level. Elements of her history, as well as her score of 9 out of 10 on the McLean Screening Instrument for Borderline Personality Disorder, indicated a possible diagnosis of borderline personality disorder. Yet, after completing a course of prolonged grief disorder therapy, both her grief and borderline symptoms were much reduced.

Conclusions: This case raises the possibility of an association between prolonged grief and borderline symptoms. Disruption of attachment relationships provides a possible way of understanding this association. The case we present raises the possibility that prolonged grief disorder may better explain symptoms in some patients presenting with borderline personality disorder symptoms.
