Abstract and Introduction

Introduction

DSM-5 defines personality disorders (PDs) as the presence of an enduring pattern of inner experience and behavior that “deviates markedly from the expectations of the individual’s culture, is pervasive and inflexible, has an onset in adulthood, is stable over time, and leads to distress or impairment.”[1] As a general rule, PDs are not limited to episodes of illness, but reflect an individual’s long-term adjustment. These disorders occur in 10% to 15% of the general population; the rates are especially high in health care settings, in criminal offenders, and in those with a substance use disorder (SUD).[2] PDs nearly always have an onset in adolescence or early adulthood and tend to diminish in severity with advancing age. They are associated with high rates of unemployment, homelessness, divorce and separation, domestic violence, substance misuse, and suicide.[3]

Psychotherapy is the first-line treatment for PDs, but there has been growing interest in using pharmacotherapy to treat PDs. While much of the PD treatment literature focuses on borderline PD,[4,5,6,7,8,9] this article describes diagnosis, potential pharmacotherapy strategies, and methods to assess response to treatment for patients with all types of PDs
