There are some psychologists/psychiatrists, Kernberg, Yoeman & Clarkin to name a few, who believe that people organized at the Borderline level of functioning often exhibit many of the traits of anti-social PD, paranoid PD, and malignant narcissim. They developed a treatment for BPD called Transference Focused Psychotherapy. Don't read their text if you want to get distressed and frustrated, because the picture they paint of us is not a pretty one.
