Recognizing and Responding to Patients with Personality Disorders.

Caring for patients with personality disorders and traits presents unique challenges for physicians and other providers. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, recognizes 10 personality disorders, which are organized into 3 clusters (A, B, and C) based on shared diagnostic features. Personality disorders or traits create difficulty in clinical and interpersonal interactions, promoting missed diagnosis or underdiagnosis, nonadherence to medical recommendations, or other dangerous outcomes. It is important to recognize patients with potential personality disorders and understand strategies to achieve optimal patient interactions and best possible medical outcomes.
