Neurotransmitters in the brain are the current focus of obsessive compulsive disorders to better address the approximately 2.5 million people in the United States diagnosed with OCD. As seems the way of psychiatry practice, a disorder is viewed and treated from one perspective for a period, then a new perspective is in the forefront. Such is the case with obsessive compulsive disorders, originally treated as a behavioral problem with psychotherapy, now considered a brain circuitry disorder that can be treated with psychopharmacotherapeutics. This issue contains topics that focus on neuroscience of the brain and genetics in relation to OCD, providing the psychiatrist a comprehensive review of the current thought, approach, diagnosis, and treatment related to OCD and its related disorders. Topics include: Etiological hypotheses of OCD - molecules to circuits; Models of obsessive compulsive and related disorders; Cognitive neuroscience of OCD; Genetics of obsessive compulsive and related disorders; Tic disorders - spearate or related disorder; Pediatric acute-onset neuropsychiatric syndrome (PANS); Body dysmorphic disorder; Trichotillomania; Hoarding disorder; Pharmacotherapy; Device based interventions; Cognitive behavioral therapy for OCD.

Obsessive-compulsive disorder (OCD) is a complex set of thoughts and behaviors that can vary greatly from person to person and can be related to and complicated by a wide range of other disorders. Clinicians are confronted with the challenge of accurately classifying its many variants and developing effective, systematic treatments for them. Some believe that OCD and related problems should be treated as subtypes of one condition; others argue that OCD is composed of a spectrum of many similar conditions that should be treated individually. In this handbook, Jonathan S. Abramowitz, Dean McKay, and Steven Taylor present an approach to diagnosis and treatment that considers subtype and spectrum concepts. They examine specific presentations of OCD—the symptoms—that are often seen in practice as well as the many disorders that may fall within the OCD spectrum. For each symptom and putative spectrum condition, they discuss empirical support, theories of etiology, and treatment issues. The volume covers cognitive-behavioral and biological factors, as well as the latest approaches to psychological and pharmacologic therapy, including complicating factors in treatment. In concluding chapters, the authors critically address the current literature on proposed subtype and spectrum disorders, consider the clinical implications of the literature, and map out a comprehensive, integrated approach for understanding OCD and related conditions. The only work on OCD that covers treatment options for specific symptoms and the full spectrum of related disorders, this handbook is a must-have for clinicians who are dedicated to improving the lives of patients with these challenging mental conditions.

The second edition of this successful pocketbook has been updated to include new developments in the diagnosis and management of patients with obsessive-compulsive and related disorders. The revised text also summarizes the implications of the publication of DSM-5 on clinical practice.

Obsessive-compulsive and related disorders (OCRDs) are both prevalent and a source of significant impairment for patients who suffer from them, yet they remain underrecognized and underdiagnosed. Handbook on Obsessive-Compulsive and Related Disorders provides comprehensive and cutting-edge coverage of OCRDs for clinicians and trainees in the context of the new classification framework established by the DSM-5. Chapters cover OCD, body dysmorphic disorder (BDD), hoarding disorder, trichotillomania (hair pulling disorder), excoriation (skin picking) disorder, and illness anxiety disorder, among other related conditions, ensuring that readers are current on both the research on and the standard of care for these illnesses. In addition, each chapter employs a logical and consistent structure, addressing diagnostic criteria and symptomatology, epidemiology, etiology and pathophysiology, comorbidities, course and prognosis, assessment and differential diagnosis, psychosocial impairment and suicidality, and other topics such as cultural and gender-related issues. Treatment approaches and considerations are explored in-depth. The Handbook's useful features are many: The first book focused on the OCRDs to be published since the development of DSM-5, it reflects a deep understanding of the disorders and the DSM-5 development process. Readers can depend on the utmost compatibility with DSM-5 because the book was edited by the chair of the DSM-5 work group, and the chair of the sub-work group, that oversaw the development of the OCRD category. The editors have provided a helpful introductory chapter that thoroughly addresses the changes from DSM-IV. The book includes a chapter on disorders that were seriously considered for, though ultimately not included in, the DSM-5 OCRD chapter and for which research offers some support for a close relationship to OCD. These include tic disorders, illness anxiety disorder (hypochondriasis), and obsessive-compulsive personality disorder. Case studies are provided in each chapter, as well as key clinical points, both of which help the reader understand, contextualize, and make use of the book's content. Recommended readings at the end of each chapter offer the opportunity to deepen understanding. The costs to society of undiagnosed and/or untreated OCRD are high in both human and financial terms, and clinicians need to master all available tools to help patients and families understand and cope with these disorders. Handbook of Obsessive-Compulsive and Related Disorders deserves a prominent position -- both in the literature and on the clinician's bookshelf.

This text is a complete, comprehensive overview of OCD and related disorders (trichotillomania, excoriation disorder, hoarding disorder, body dysmorphic disorder, and tic disorders). Based on the DSM-5, the book uses the latest evidence-based information regarding treatments including medication options, behavioral therapies, alternative treatments, and developments in surgical treatment.

Obsessive-Compulsive and Related Disorders (OCRDs) have received considerable attention over the past two decades culminating with the inclusion of a new classification category of "Obsessive-Compulsive and Related Disorders" (OCRDs) in DSM-5. This group of conditions includes OCD along with two newly minted conditions (Hoarding Disorder and Excoriation Disorder) and others previously classified as Somatoform Disorders (Body Dysmorphic Disorder) and Impulse Control Disorders (Hair Pulling Disorder). The implications for research on these conditions, as well as their relations with one another, are significant since their aggregation is based on putative central mechanisms with limited empirical support to date. Indeed, the past decades have seen a dramatic surge in research on OCRDs. Such scholarship has occurred across several domains including clinical phenomenology, assessment, and psychological therapies. A complete synthesis of the emerging data across these domains would be beyond the scope of a single journal article or series of articles while having the ability to comprehensively discuss advances in the field and stimulating in these areas Many of the available textbooks, although meritorious in their own right, are outdated and do not address the most recent research advances and emerging clinical implications. Indeed, the past decade has seen a tremendous growth in knowledge on treatment, assessment, treatment augmentation, and basic science that is not contained fully within existing volumes (see discussion of specific texts further below). Thus, providing a comprehensive textbook that addresses recent advances will provide a much needed update to the field of OCRDs. Furthermore, recent texts primarily address OCRDs from a biological standpoint, neglecting psychosocial theoretical and intervention approaches that enjoy the most empirical support of any conceptual and treatment approaches for most of the relevant conditions. As a result, the literature has been dominated by a single predominant perspective, which does not fully represent the available data or perspectives of front-line clinicians and researchers alike. As researchers and clinicians will be increasingly focused on this topic in light of the changes to DSM-5 - together with the dearth of current objective available information - this book will be a timely addition to the literature in guiding clinicians in advances in OCRDs that will impact their practice. Third, a number of conditions outside the OCRD chapter in DSM-5 are often proposed as "related" to OCD (e.g., misophonia).

Advanced Casebook of Obsessive-Compulsive and Related Disorders: Conceptualizations and Treatment presents a synthesis of the emerging data across clinical phenomenology, assessment, psychological therapies and biologically-oriented therapies regarding obsessive compulsive disorders, including hoarding, skin picking, body dysmorphic and impulse control disorders. Following the re-classification of such disorders in the DSM-5, the book addresses recent advances in treatment, assessment, treatment augmentation and basic science of OCRDs. The second half of the book focuses on the treatment of OCRDs, covering both psychological therapies (e.g. inhibitory learning informed exposure, tech-based CBT applications) and biologically oriented therapies (e.g. neuromodulation). - Includes psychosocial theoretical and intervention approaches - Addresses newly proposed clinical entities, such as misophonia and orthorexia - Examines neurobiological features of OCRDs across the lifespan
