New preliminary research finds three clinically-relevant Borderline classes.
- Borderline Personality Disorder (BPD) is a relatively common problem, often difficult to treat.
- Because there are hundreds of possible symptom combinations, having a system for classifying BPD to guide treatment is highly desirable.
- New research using “Latent Class Analysis” identifies 3 distinct types of BPD.
- This information is useful for clinical treatment and self-assessment, and sets the stage for future research and development.

While BPD is at times romanticized, even valorized, in the media because of the excitement that goes along with the heady, often exhilarating, ups, the downside of the disorder is too often tragedy and isolation.
