This is a very comprehensive handbook covering the phenomenology, pathogenesis and treatment of obsessive-compulsive disorder (OCD). It is truly a handbook fitting neatly into the pocket/briefcase. The chapters are laid out in a logical format, guiding the reader through the aetiology of OCD before proceeding to management aspects. Their content is sufficiently detailed to guide practice without being overwhelming, while an excellent bibliography at the end of each chapter allows further, more detailed, reading. The layout of the chapters also lends to easy accessibility with the use of headings and boxes, figures and tables to highlight information.

The book considers the phenomenology of OCD and helpfully outlines the diagnostic criteria, paying particular attention to differential diagnoses. It highlights the chronic and hidden nature of the disorder. A comprehensive overview of the pathogenesis of OCD is provided considering the areas of neuroanatomy, neuro-chemistry, neurogenetics, neuroimmunology and neuroethology. In my experience psychoeducation is an invaluable tool in engaging patients in therapy and this chapter allows the clinician to become proficient in the same.

A very comprehensive presentation of the available evidence base for treatment of OCD follows. Short commentaries on each study are provided. I particularly liked the section dealing with antidepressant side-effects and drug interactions. Included is a discussion of psychotherapeutic treatment; however, it would perhaps have been useful to discuss further the cognitive theories underlying the belief systems in OCD. These I have found particularly helpful in psychoeducation and engagement in therapy and would have added to the richness of this chapter. Particularly useful is the chapter providing rating scales, reference books and websites for patients and clinicians. Overall an enjoyable and clinically useful book.
