Borderline personality disorder (BPD) is one of the more vexing forms
of psychopathology for researchers and clinicians alike to understand.
Currently, the etiology and pathogenesis of the disorder remain unclear;
however, steady progress has been made in several important areas that
bear upon informing a more complete understanding of this condition. Long
known to clinicians in office practice and mental health staff at clinics
and hospitals, BPD is a heterogenous phenotype characterized by a complex
array of features such as emotional dysregulation, interpersonal
dysfunction, impulsivity, self-damaging behaviors, excessive anger and
fear, and identity disturbance (American Psychiatric
Association, 1994). The individual afflicted with BPD frequently
experiences substantial social and occupational impairment, as well as
frequent emotional turmoil. Those individuals who spend considerable time
with a BPD-affected person, such as parents, partners, spouses, children,
coworkers, and others, also encounter appreciable stresses and strains
associated with the impact of BPD on the family, social, and occupational
milieu.
