title: Borderline diagnoses.
abstract: The author describes the development of the borderline concept and the apparent inaccuracy of the original hypothetical framework. The signs and symptoms used to describe a "borderline syndrome" are often shared with other psychiatric illnesses. The author recommends that clinicians consider patients with only those features as "undiagnosed" until further research determines whether a distinct syndrome exists.
