The DSM-5-TR Handbook of Differential Diagnosis is the preeminent guide to differential diagnosis for both clinicians and students learning psychiatric diagnosis. Fully updated to reflect the recent Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), this handbook includes two newly developed diagnostic trees (for dissociative symptoms and repetitive pathological behaviors). This indispensable guide offers a rich selection of diagnostic lenses through which to consider symptomatic presentations, grounded in the latest research and standards of practice.

Written by the DSM-5-TR Editor, an expert on psychiatric diagnosis and assessment, the handbook guides clinicians and students on how to differentiate between disorders with similar presentations in an accessible, easy-to-use format. An assortment of approaches to differential diagnosis and a number of features designed to benefit the evaluation include:

• A six-step framework for diagnosing patients that proceeds from determining if the presenting symptoms are due to a substance/medication or a medical condition, to establishing the boundary between disorder and normality, to determining the primary disorder, and differentiating adjustment disorders from other mental disorders.
• Thirty symptom-oriented decision trees, two of which are new to this edition, that provide detailed decision points to facilitate the process of generating the differential diagnosis based on the presenting symptoms and eliminate formulating premature conclusions.
• Sixty-seven differential diagnosis tables, one for each of the most important disorders in DSM-5-TR, cross-referenced with the terminal branches of the decision trees presented in the handbook and that provide a head-to-head comparison of each disorder, highlighting similarities and differences.
• The DSM-5-TR Classification, to facilitate coding and to provide an overview of all the DSM-5-TR diagnoses that must be considered in formulating a differential diagnosis.
