Obsessive-Compulsive Disorder is a chronic anxiety-spectrum condition marked by intrusive, unwanted thoughts, urges, or images (obsessions) that drive ritualized, repetitive behaviors or mental acts (compulsions) performed to neutralize distress. Under DSM-5 these obsessions and compulsions are time-consuming (typically more than one hour per day) or cause clinically significant distress and impairment, and the person often recognizes the rituals as excessive yet cannot resist them. Common presentations include contamination fears with washing, pathological doubt with checking, symmetry and ordering, and intrusive aggressive or taboo thoughts.
