Obsessive-Compulsive Disorder (OCD)
What is obsessive-compulsive disorder (OCD)?
Obsessive-compulsive disorder (OCD) is a type of mental illness that causes repeated unwanted thoughts. To get rid of the thoughts, a person does the same tasks over and over. For example, you may fear that everything you touch has germs on it. So to ease that fear, you wash your hands over and over again.
OCD is a chronic, or long-term, illness that can take over your life, hurt your relationships, and limit your ability to work or go to school.
What causes OCD?
Experts don't know the exact cause of obsessive-compulsive disorder. Research suggests that there may be a problem with the way one part of the brain sends information to another part. Not having enough of a brain chemical called serotonin may help cause the problem.
What are the symptoms?
Symptoms of obsessive-compulsive disorder tend to come and go over time and range from mild to severe. Anxiety is the most common symptom. For example, you may have an overall sense that something terrible will happen if you don't do a certain task, such as check again and again to see whether the stove is on. If you fail to check, you may suddenly feel tense or anxious or have a nagging sense that you left something undone.
Symptoms of the disorder include:
The obsessions or compulsions usually take up a lot of time-more than 1 hour a day. They greatly interfere with your normal routine at work or school, and they affect social activities and relationships.
Sometimes people may understand that their obsessions and compulsions are not real. But at other times they may not be sure, or they may believe strongly in their fears.
How is OCD diagnosed?
Your doctor can check for obsessive-compulsive disorder by asking about your symptoms and your past health. He or she may also do a physical exam. It's important to talk to your doctor if you think you have OCD. Many people with the disorder go without treatment, because they are afraid or embarrassed to talk to a doctor.
How is it treated?
Treatment includes medicines and counseling. Using both often works best.
Antidepressant medicines called selective serotonin reuptake inhibitors (SSRIs) are most commonly used. Examples of these medicines include Prozac and Zoloft. You may begin to feel better in about 1 to 3 weeks after you start taking medicine. But it can take as long as 12 weeks to see more improvement. If you have concerns about your medicine, or if you do not start to feel better by 3 weeks, talk to your doctor. He or she may increase the dose or change to a different medicine.
Counseling for the disorder includes a type of cognitive-behavioral therapy called exposure and response prevention. This therapy slowly increases your contact with the thing that causes worries or false beliefs. For example, if you were worried about getting germs from things you touch, you would touch an object you believe has germs and then not wash your hands afterward. You would keep doing that until you could do it without feeling anxious. This can be hard at first. But with the help of a counselor, this therapy can reduce your symptoms over time.
Other cognitive therapy may also help change the false beliefs that lead to OCD behaviors.
Treatment can make your symptoms less severe. But you may still have some mild symptoms after you begin treatment.
