Answer

BPD and NPD are both characterized by a constant need for attention, as well as affective instability and unpredictable behavior. However, the patient with NPD has a much greater sense of grandiosity than the patient with BPD and requires attention that is specifically of the admiring kind. The patient with BPD also demonstrates more self-destructive behaviors (eg, cutting and self-mutilation) and has a much less stable sense of self than the patient with NPD does. [17]
