What is OCD? Obsessive-compulsive disorder (OCD) is a mental health disorder marked by obsessions and compulsions. Obsessions are unwanted, intrusive thoughts, images, or urges that cause significant distress. Compulsions are repetitive behaviors or mental acts that a person feels driven to perform, often to reduce the distress caused by obsessions or to prevent something bad from happening.
OCD can center on many different fears and concerns, and compulsions are not always visible to others. While the specific thoughts and behaviors can vary widely from person to person, they can become time-consuming, interfere with daily life, and cause significant distress.
Common obsessions include: contamination, harm/violence, perfectionism, and religious or moral fear. Common compulsions include: washing and cleaning, checking for mistakes, repeating, ordering/arranging, and avoidance.
The International OCD Foundation provides a list of common obsessions and compulsions, with information on each symptom. Learn more and find resources at https://iocdf.org/programs/ocdweek/.
