This chapter presents an overview of the nature, assessment, and treatment of obsessive-compulsive and related disorders (OCRD), including obsessive-compulsive disorder (OCD), body dysmorphic disorder (BDD), hoarding disorder (HD), hair-pulling disorder (HPD), and skin-picking disorder (SPD). Specifically, we review the DSM-V diagnostic criteria, epidemiology and impact, clinical features and course, and etiological insights for each of these disorders in turn. Next, we discuss key points to consider when making a differential diagnosis with disorders outside the OCRD category. From there, we turn to a discussion of the assessment and treatment of these disorders using pharmacological, cognitive-behavioral, and neuromodulation interventions. Future directions in the research on OCRDs then follows.
