This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

Traditionally, impulsive and compulsive behaviors have been categorized as fundamentally distinct. However, patients often exhibit both of these behaviors. This common comorbidity has sparked renewed interest in the factors contributing to the disorders in which these behaviors are prominent. Impulsivity and Compulsivity applies a provocative spectrum model to this psychopathology. The spectrum model is consistent with a dimensional model for psychopathology and considers the dynamic interaction of biopsychosocial forces in the development of impulsive and compulsive disorders. In this important work on impulsive/compulsive psychopathology, leading researchers and clinicians share their expertise on the phenomenological, biological, psychodynamic, and treatment aspects of these disorders. Differential diagnosis, comorbidity of the impulsive-compulsive spectrum of disorders, and assessment by the seven-factor model of temperament and character are discussed. Chapters are also dedicated to the antianxiety function of impulsivity and compulsivity, defense mechanisms in impulsive disorders versus obsessive-compulsive disorders, and the unique aspects of psychotherapy with impulsive and compulsive patients. Clinical researchers and clinicians will be enlightened by this exceptional work. The information provided is supplemented with clinical vignettes, and the final chapter provides a synthetic summary that offers a unified, dynamic approach to impulsive and compulsive behavior.

The five-year process of preparing for the revision of the Diagnostic and Statistical Manual (DSM) has been organized around a series of conferences convened by the American Psychiatric Association, in collaboration with the World Health Organization and the U.S. National Institutes of Health, to address the future of psychiatric diagnosis. Obsessive-Compulsive Spectrum Disorders: Refining the Research Agenda for DSM-V is the fruit of one of those conferences and presents the most academically sound, thought-provoking, and timely papers from the proceedings. As the conference and book demonstrate, recent advances in psychiatric diagnosis suggest a new approach to obsessive-compulsive disorder (OCD) classification: Research into the pathogenesis of OCD increasingly supports reclassification out of the anxiety disorders and into a separate group of obsessive-compulsive-related disorders (OCRDs). The relationships among OCRDs may be better defined, delineated, and understood if the current categorical diagnostic approach is supplemented with a dimensional approach which assesses obsessive-compulsive symptom domains. Obsessive-compulsive disorders are believed to be underdiagnosed in patients who complain of broad symptoms of anxiety, and reclassification of OCD as an OCRD would promote more careful examination of distinct obsessive-compulsive symptoms, yield more accurate diagnosis, and result in more effective treatments. Reclassification may facilitate future research directions in examining the biological underpinnings of these disorders. In addition to examining the genetic, neurological, and ethno-cultural bases for OCRDs, the book gives special attention to disorders that cross current diagnostic categories, including: Body dysmorphic disorder (BDD) Tourette's syndrome and trichotillomania Impulse-control disorders The process leading to publication of DSM-V is by its nature an exhaustive and complex one, and the conferences play a critical role in reviewing relevant research, assessing the status of scientific knowledge, and advancing that knowledge base. Obsessive-Compulsive Spectrum Disorders: Refining the Research Agenda for DSM-V represents the cutting-edge thinking that will culminate in new diagnoses, classifications, and standards of practice for this debilitating set of disorders. Clinicians and academicians will be fascinated by this glimpse into the next generation of the DSM-V.

While other texts provide general information on obsessive-compulsive disorder (OCD), this is the first book to make a wider, inclusive examination of the disorders that appear to be closely linked to OCD (i.e., body dysmorphic disorder, trichotillomania, Tourette's syndrome, etc.) and review the diagnostic, biological, and treatment issues surrounding their relationship. Obsessive-Compulsive Related Disorders discusses the way compulsivity and impulsivity are studied and understood in the diagnosis and treatment of these obviously related disorders -- should they be diagnosed by categories, or in the context of dimensional models? Subsequent chapters also examine serotonin's role in these psychiatric disorders.

Research in the area of impulse control disorders has expanded exponentially. The Oxford Handbook of Impulse Control Disorders provides researchers and clinicians with a clear understanding of the developmental, biological, and phenomenological features of a range of impulse control disorders, as well as detailed approaches to their treatment.

According to recent estimates, one in 50 adults in the United States has obsessive-compulsive disorder and twice that many have had this disorder at some point in their lives. This issue includes articles on the phenomenology of OCD, hypochondriasis, body dysmorphic disorder, genetics and OCD, trichotillomania, Tourette's syndrome, addictive disorders, pharmacotherapy, psychotherapy, and immunology

A review of current literature on obsessive compulsive disorder (OCD) and its associated spectrum conditions, including body dysmorphic disorder (BDD), hoarding, trichotillomania, tic disorders, and Tourette's Syndrome.
