The most common personality disorder here and abroad, borderline personality disorder is often misdiagnosed or underdiagnosed. Left untreated, it causes marked distress and impairment in social, occupational, and role functioning, with high rates of self-destructive behavior (attempted and completed suicide). Its pervasive pattern of impulsivity and instability of interpersonal relationships, affects, and self-image begins in early adulthood and presents in a variety of contexts. Developed primarily by psychiatrists in active clinical practice, the revised edition of this popular work offers an updated synthesis of current scientific knowledge and rational clinical practice for patients with borderline personality disorder--with the important caveat that clinicians should consider, but not limit themselves to, the treatments recommended here. The summary of treatment recommendations is keyed according to the level of confidence with which each recommendation is made and coded to show the nature of its supporting evidence. Highly informative and easy to use, this eminently practical volume is organized into three major parts: Part A contains treatment recommendations (Section I, treatment summaries; Section II, treatment plans; Section III, special clinical considerations; and Section IV, risk management issues during treatment), Part B presents the evidence underlying these treatment recommendations (Section V, an overview of DSM-IV-TR criteria, prevalence rates, and natural history and course; and Section VI, a review of existing treatment literature), and Part C summarizes those areas in which better research data are needed. Remarkably concise and comprehensive, this practice guideline continues to be an indispensable reference for every clinician who treats patients with this heterogeneous and complex disorder.
