Obsessive-compulsive disorder: A psychiatric disorder characterized by obsessive thoughts and compulsive actions, such as cleaning, checking, counting, or hoarding. Obsessive-compulsive disorder (OCD), one of the anxiety disorders, is a potentially disabling condition that can persist throughout a person's life. The individual who suffers from OCD becomes trapped in a pattern of repetitive thoughts and behaviors that are senseless and distressing but extremely difficult to overcome. OCD occurs in a spectrum from mild to severe, but if severe and left untreated, can destroy a person's capacity to function at work, at school, or even in the home.
The obsessions are unwanted ideas or impulses that repeatedly well up in the mind of the person with OCD. Persistent fears that harm may come to self or a loved one, an unreasonable concern with becoming contaminated, or an excessive need to do things correctly or perfectly, are common. Again and again, the individual experiences a disturbing thought, such as, "My hands may be contaminated--I must wash them"; "I may have left the gas on"; or "I am going to injure my child." These thoughts are intrusive, unpleasant, and produce a high degree of anxiety. Sometimes the obsessions are of a violent or a sexual nature, or concern illness.
In response to their obsessions, most people with OCD resort to repetitive behaviors called compulsions. The most common of these are washing and checking. Other compulsive behaviors include counting (often while performing another compulsive action such as hand washing), repeating, hoarding, and endlessly rearranging objects in an effort to keep them in precise alignment with each other. Mental problems, such as mentally repeating phrases, listmaking, or checking are also common. These behaviors generally are intended to ward off harm to the person with OCD or others. Some people with OCD have regimented rituals while others have rituals that are complex and changing. Performing rituals may give the person with OCD some relief from anxiety, but it is only temporary.
The old belief that OCD was the result of life experiences has been weakened by the growing evidence that biological factors are a primary contributor to the disorder. The fact that OCD patients respond well to specific medications that affect the neurotransmitter serotonin suggests the disorder has a neurobiological basis.
OCD is sometimes accompanied by depression, eating disorders, substance abuse disorder, a personality disorder, attention deficit disorder, or another of the anxiety disorders. Co-existing disorders can make OCD more difficult both to diagnose and to treat.
Treatment is by cognitive behavioral therapy and/or medication. One patient may benefit significantly from behavior therapy, while another will benefit from pharmacotherapy. Some others may use both medication and behavior therapy. Others may begin with medication to gain control over their symptoms and then continue with behavior therapy.
The neurotransmitter serotonin can significantly decrease the symptoms of OCD. The first serotonin reuptake inhibitor (SRI) specifically approved for the use in the treatment of OCD was the tricyclic antidepressant clomipramine (AnafranilR). It was followed by fluoxetine (ProzacR), fluvoxamine (LuvoxR), and paroxetine (PaxilR). Large studies have shown that more than three-quarters of patients are helped by these medications. And in more than half of patients, medications relieve symptoms of OCD by diminishing the frequency and intensity of the obsessions and compulsions. Improvement usually takes at least three weeks or longer. If a patient does not respond well to one of these medications, or has unacceptable side effects, another SRI may give a better response. Medications are of help in controlling the symptoms of OCD, but often, if the medication is discontinued, relapse will follow. Indeed, even after symptoms have subsided, most people will need to continue with medication indefinitely, perhaps with a lowered dosage.
Traditional psychotherapy, aimed at helping the patient develop insight into his or her problem, is generally not helpful for OCD. However, a specific behavior therapy approach called "exposure and response prevention" is effective for many people with OCD. In this approach, the patient deliberately and voluntarily confronts the feared object or idea, either directly or by imagination. At the same time the patient is strongly encouraged to refrain from ritualizing, with support and structure provided by the therapist, and possibly by others whom the patient recruits for assistance. For example, a compulsive hand washer may be encouraged to touch an object believed to be contaminated, and then urged to avoid washing for several hours until the anxiety provoked has greatly decreased. Treatment then proceeds on a step-by-step basis, guided by the patient's ability to tolerate the anxiety and control the rituals. As treatment progresses, most patients gradually experience less anxiety from the obsessive thoughts and are able to resist the compulsive urges.
Studies of behavior therapy for OCD have found it to be a successful treatment for the majority of patients who complete it. For the treatment to be successful, it is important that the therapist be fully trained to provide this specific form of therapy. It is also helpful for the patient to be highly motivated and have a positive, determined attitude. The positive effects of behavior therapy endure once treatment has ended.
