Obsessive-Compulsive Disorder (OCD) is far more than just a preference for order—it’s a complex condition marked by intrusive thoughts and repetitive behaviors that disrupt daily life. In this episode, we’ll define obsessions and compulsions, review the diagnostic criteria, and discuss how these patterns interfere with functioning despite the individual’s awareness of their irrational nature. We’ll explore the epidemiology of OCD, including typical age of onset and prevalence, along with physiological factors such as genetic influences and biochemical imbalances. Nursing assessments and management strategies will be highlighted, covering psychopharmacology, patient education, and behavioral techniques like response prevention and thought stopping. Finally, we’ll distinguish OCD from related disorders—trichotillomania, excoriation disorder, body dysmorphic disorder, and hoarding disorder—equipping nurses with the knowledge to provide accurate, compassionate, and effective care.
