Obsessive–compulsive disorder (OCD) is a mental disorder characterized by intrusive, unwanted thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) performed to reduce the distress caused by these thoughts.
Obsessions often involve themes such as fear of contamination, aggressive or sexual thoughts, religious or moral concerns (scrupulosity), or a need for symmetry and exactness.
Compulsions may include excessive cleaning, checking, counting, arranging items in a precise order, or mental rituals like repeating words silently.
These symptoms typically consume at least one hour per day and significantly impair daily functioning, relationships, or quality of life.
