Although Borderline Personality Disorder (BPD) overlaps considerably with Major Depression, recent studies of biology, genetics and childhood trauma have demonstrated that there are substantial differences between the two disorders. It is suggested that their apparent relationship is rather nonspecific. In this paper, the author emphasizes that the core symptom of BPD is impulsiveness, which causes depressive symptoms and/or is induced by depressive episodes, forming a vicious cycle. Furthermore, in BPD patients, depressive symptoms are modified by impulsiveness, masochism, vanity, despair, and difficulties in interpersonal relationships. The author concludes that BPD is not a homogeneous but heterogeneous syndrome, classified into subtypes: depressive type, impulsive type, and identity diffusion type. Treatment needs to be considered according to these types.
