Your questions about OCD (obsessive-compulsive disorder) may be answered by this document provided directly by the US National Institute of Mental Health.
What is OCD?
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 case histories in this brochure are typical for those who suffer from obsessive-compulsive disorder–a disorder that can be effectively treated. However, the characters are not real.
How Common Is OCD?
For many years, mental health professionals thought of OCD as a rare disease because only a small minority of their patients had the condition. The disorder often went unrecognized because many of those afflicted with OCD, in efforts to keep their repetitive thoughts and behaviors secret, failed to seek treatment. This led to underestimates of the number of people with the illness. However, a survey conducted in the early 1980s by the National Institute of Mental Health (NIMH)–the Federal agency that supports research nationwide on the brain, mental illnesses, and mental health–provided new knowledge about the prevalence of OCD. The NIMH survey showed that OCD affects more than 2 percent of the population, meaning that OCD is more common than such severe mental illnesses as schizophrenia, bipolar disorder, or panic disorder. OCD strikes people of all ethnic groups. Males and females are equally affected. The social and economic costs of OCD were estimated to be $8.4 billion in 1990 (DuPont et al, 1994).
Although OCD symptoms typically begin during the teenage years or early adulthood, recent research shows that some children develop the illness at earlier ages, even during the preschool years. Studies indicate that at least one-third of cases of OCD in adults began in childhood. Suffering from OCD during early stages of a child’s development can cause severe problems for the child. It is important that the child receive evaluation and treatment by a knowledgeable clinician to prevent the child from missing important opportunities because of this disorder.
Key Features of OCD
These 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.
People with OCD show a range of insight into the senselessness of their obsessions. Often, especially when they are not actually having an obsession, they can recognize that their obsessions and compulsions are unrealistic. At other times they may be unsure about their fears or even believe strongly in their validity.
Most people with OCD struggle to banish their unwanted, obsessive thoughts and to prevent themselves from engaging in compulsive behaviors. Many are able to keep their obsessive-compulsive symptoms under control during the hours when they are at work or attending school. But over the months or years, resistance may weaken, and when this happens, OCD may become so severe that time-consuming rituals take over the sufferers’ lives, making it impossible for them to continue activities outside the home.
Shame and Secrecy
OCD sufferers often attempt to hide their disorder rather than seek help. Often they are successful in concealing their obsessive-compulsive symptoms from friends and coworkers. An unfortunate consequence of this secrecy is that people with OCD usually do not receive professional help until years after the onset of their disease. By that time, they may have learned to work their lives–and family members’ lives–around the rituals.
OCD tends to last for years, even decades. The symptoms may become less severe from time to time, and there may be long intervals when the symptoms are mild, but for most individuals with OCD, the symptoms are chronic.
