Exploring various approaches to psychiatric disorders, including neurobiology, dimensional personality assessment, behavioural science, and psychodynamic and cognitive theories, this book lucidly illustrates each approach's strengths and weaknesses and suggests how clinicians can interweave them in working with patients. Using clinical vignettes and recent research findings to illustrate the connections between phenomenology, pathophysiology, and treatment, it covers all of the major psychiatric disorders and includes tables listing their DSM-IV-TR diagnostic criteria.
