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the field and stimulating in these areas Many of the available textbooks, although meritorious in their own right, are outdated and do not address the most recent research advances and emerging clinical implications.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).

Written for clinicians, this book presents in detail the diagnosis, clinical picture, pharmacotherapeutic and psychotherapeutic treatments for obsessive-compulsive disorder and disorders traditionally included in an obsessive-compulsive spectrum. The book draws on the author's extensive experience as well as reviewing the published evidence, including controlled trials, case series, and case reports. Each chapter ends with treatment planning guidelines summarizing appropriate evaluation and treatment strategies. An extended chapter details the use of all medications that have been reported effective for these disorders and the management of common and uncommon drug interactions and side effects. The book's appendices contain useful symptom rating scales, provide access to mental health organizations and to printed and Internet materials for patient education, and list international proprietary names for the drugs discussed. This is an essential resource and practical guide to treatment planning for psychiatrists and other mental health professionals, whether they favor pharmacological or cognitive-behavioral approaches.

With the publication of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), much has changed about the conceptualization of obsessive-compulsive disorder and its associated spectrum conditions. Breaking free from the previous category of anxiety disorders, a new diagnostic category of "obsessive-compulsive and related disorders" (ORCDs) has emerged. This new categorization has provided an opportunity to enhance our understanding of these unique disorders and to address new research questions. The second edition of The Oxford Handbook of Obsessive-Compulsive and Related Disorders presents the latest information, from leaders in the field about the epidemiology, phenomenology, assessment, and treatment of ORCDs. The volume begins by reviewing the prevalence and profiles of obsessive-compulsive disorder, body dysmorphic disorder, hoarding disorder, trichotillomania (hair-pulling disorder), and excoriation (skin-picking) disorder. Chapter authors then discuss modern conceptualizations of the OCRDs, including neurocircuitry, genetic, behavioral, and cognitive models. From here, assessment strategies are reviewed, followed by state-of-the-science biological and psychological treatments, including pharmacotherapy, neurosurgical strategies, behavioral therapies, and cognitive therapies. Finally, the volume examines the presentation and treatment of OCRDs across cultures as well as in special populations including children and older adults.

This handbook examines evidence-based treatment of obsessive-compulsive and related disorders for a broad clinical audience. Focusing on both children and adults with these conditions, it discusses various manifestations of OCD (e.g., contamination, perfectionism), related conditions (e.g., hoarding, trichotillomania, and Tourette syndrome), and cases with complicating factors. Chapters describe case specifics, offer assessment guidelines, and illustrate evidence-based psychotherapy. Case examples depict real-life complexities of presentation, notably in terms of comorbid conditions and hard-to-treat subpopulations. Topical areas addressed in the Handbook include: Phenomenology, assessment, and treatment of multiple types of OCD in adults and children. Treating “not just right experiences” in children with OCD. Treating obsessive compulsive disorder in very young children. Treatment of OCD comorbid with other disorders like depression and Autism Spectrum Disorder. Treatment of OCD when presenting with complicating factors like limited insight, extreme family accommodation, and poor motivation. The Clinical Handbook of Obsessive-Compulsive and Related Disorders is an essential resource for clinicians and professionals as well as researchers, and graduate students in clinical psychology, psychiatry, social work, counseling programs, pediatrics, public health, and related disciplines.

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.

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.

In this issue, guest editors bring their considerable expertise to this important topic.Provides in-depth reviews on the latest updates in the field, providing actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize

Complexities in Obsessive Compulsive and Related Disorders is a comprehensive text that addresses recent advances for a much needed update to the field of OCRDs.

Clinical Guide to Obsessive Compulsive and Related Disorders is a complete, comprehensive overview of OCD and related disorders (trichotillomania, excoriation disorder, hoarding disorder, body dysmorphic disorder, and tic disorders). The book covers underlying causes, clinical presentations and treatments. The book serves as a primer for clinicians in training and those already in practice who have little if any background in these disorders. It discusses the pharmacological and psychosocial treatments for both adults and children with an emphasis on providing practical information for clinicians to use in their everyday practices. Based on the DSM-5, the book uses the latest evidence-based information regarding treatments including medication options, behavioral therapies, alternative treatments, and recent developments in surgical treatment. This book will provide students, residents, interns and even veteran clinicians with a basic understanding of OCD and disorders that are often associated with OCD. In addition, members of the public and those affected by these disorders may use this book to enhance their personal knowledge of the subject matter presented.

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
