Purpose of the ReviewThis review summarizes advances in treatments for adults with borderline personality disorder (BPD) in the last 5 years.Recent FindingsEvidence-based advances in the treatment of BPD include a delineation of generalist models of care in contrast to specialist treatments, identification of essential effective elements of dialectical behavioral therapy (DBT), and the adaptation of DBT treatment to manage post-traumatic stress disorder (PTSD) and BPD. Studies on pharmacological interventions remain limited and have not provided evidence that any specific medications can provide stand-alone treatment.SummaryThe research on treatment in BPD is leading to a distillation of intensive packages of treatment to be more broadly and practically implemented in most treatment environments through generalist care models and pared down forms of intensive treatments (e.g., informed case management plus DBT skills training groups). Evidence-based integrations of DBT and exposure therapy for PTSD provide support for changing practices to simultaneously treat PTSD and BPD.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. Such consultations require the integration of medical and psychiatric knowledge. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss the diagnosis and management of conditions confronted. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.Dr Unruh is an attending psychiatrist at McLean Hospital, Belmont, Massachusetts, and an instructor in psychiatry at Harvard Medical School, Boston, Massachusetts. Dr Nejad is an instructor in psychiatry at Harvard Medical School, Boston, Massachusetts, an attending physician on the Psychiatric Consultation Service at Massachusetts General Hospital, Boston, and the director of the Burns and Trauma Psychiatric Consultation Service at Massachusetts General Hospital, Boston. Mr Stern is a research assistant in the Department of Psychiatry at Massachusetts General Hospital, Boston. Dr Stern is chief of the Psychiatric Consultation Service at Massachusetts General Hospital, Boston, and a professor of psychiatry at Harvard Medical School, Boston, Massachusetts.Dr Stern is an employee of the Academy of Psychosomatic Medicine, has served on the speaker's board of Reed Elsevier, is a stock shareholder in WiFiMD (Tablet PC), and has received royalties from Mosby/Elsevier and McGraw Hill. Drs Unruh and Nejad and Mr Stern report no financial or other affiliations relevant to the subject of this article.

The authors review four theories that propose different conceptualizations of borderline personality disorder's (BPD) core psychopathology: excess aggression, emotional dysregulation, failed mentalization, and interpersonal hypersensitivity. The theories are compared in their ability to explain BPD's coaggregation of four usually distinct sectors of psychopathology, their high overlap with other disorders, their ability to distinguish BPD from other disorders, their integration of heritability, and their clinical applicability. The aims of this review are to increase awareness of these theories, to stimulate improved theories, and to f ster testable hypotheses so that research can advance our knowledge about BPD's core.
