Obsessions in obsessive compulsive disorder (OCD) are upsetting and unwanted thoughts, images, and impulses that constantly recur. So distressing are they that people with OCD use a variety of elaborate and time-consuming rituals to try to make them disappear, or to prevent the harm they seem to predict. These rituals are called compulsions and they can be actions or thoughts. Scientists have identified five ‘dimensions’: inflicting harm, or failing to prevent harm; symmetry; contamination; sex, violence, religion; and hoarding.
