Grounded in author Allen Frances s extensive clinical experience, this practical guide helps the busy clinician find the right psychiatric diagnosis and avoid the many pitfalls that lead to errors. For each DSM disorder, Frances provides the appropriate ICD-9 code, a useful screening question, a colorful descriptive prototype, lucid diagnostic tips, and a discussion of other disorders that must be ruled out. The book closes with an index of the most common presenting symptoms, listing possible diagnoses that must be considered for each. Frances was instrumental in the development of past editions of the DSM and provides helpful cautions on questionable aspects of DSM-5.
