What is Obsessive Compulsive Disorder (OCD)?

According to the international OCD foundation, Obsessive compulsive disorder (OCD) is a mental health disorder that affects people of all ages and walks of life, and occurs when a person gets caught in a cycle of obsessions and compulsions. Obsessions are unwanted, intrusive thoughts, images, or urges that trigger intensely distressing feelings. Compulsions are behaviors an individual engages in to attempt to get rid of the obsessions and/or decrease his or her distress.

Obsessions are thoughts, images or impulses that occur over and over again and feel outside of the person’s control. Individuals with OCD do not want to have these thoughts and find them disturbing. In most cases, people with OCD realize that these thoughts don’t make any sense.  Obsessions are typically accompanied by intense and uncomfortable feelings such as fear, disgust, doubt, or a feeling that things have to be done in a way that is “just right.” In the context of OCD, obsessions are time consuming and get in the way of important activities the person values. This last part is extremely important to keep in mind as it, in part, determines whether someone has OCD — a psychological disorder — rather than an obsessive personality trait.

Compulsions are the second part of obsessive compulsive disorder. These are repetitive behaviors or thoughts that a person uses with the intention of neutralizing, counteracting, or making their obsessions go away. People with OCD realize this is only a temporary solution but without a better way to cope they rely on the compulsion as a temporary escape. Compulsions can also include avoiding situations that trigger obsessions. Compulsions are time consuming and get in the way of important activities the person values.
