Where did the term "borderline" come from, and what does it mean?
The term "borderline" was first used by early psychiatrists to describe people who were thought to be on the "border" between diagnoses. At the time, the system for diagnosing mental illness was far less sophisticated than it is today, and "borderline" referred to individuals who did not fit neatly into the two broad categories of mental disorder: psychosis or neurosis.
Today, far more is known about BPD, and it is no longer thought of as being related to psychotic disorders (and the term "neurosis" is no longer used in our diagnostic system). Instead, BPD is recognized as a disorder characterized by intense emotional experiences and instability in relationships and behavior.
Many experts are now calling for BPD to be renamed, because the term "borderline" is outdated and because, unfortunately, the name has been used in a stigmatizing way in the past. Suggestions for the new name have included: "Emotion Dysregulation Disorder," Unstable Personality Disorder," and "Complex Posttraumatic Stress Disorder."
