Historically, the term “borderline” has been the subject of much debate. BPD used to be considered on the “borderline” between psychosis and neurosis. The name stuck, even though it doesn’t describe the condition very well and, in fact, may be more harmful than helpful. The term “borderline” also has a history of misuse and prejudice—BPD is a clinical diagnosis, not a judgment.
Current ideas about the condition focus on ongoing patterns of difficulty with self-regulation (the ability to soothe oneself in times of stress) and trouble with emotions, thinking, behaviors, relationships and self-image. Some people refer to BPD as “Emotion Disregulation.”
