OCD is a common disorder that affects adults, adolescents, and children all over the world. Most people are diagnosed at about age 19, with boys typically experiencing earlier onset than girls.
The causes of OCD are unknown.
Signs and symptoms
People with OCD may have obsessions, compulsions, or both. These symptoms can interfere with all aspects of life, such as work, school, and personal relationships.
Obsessions are repeated thoughts, urges, or mental images that cause anxiety. Common symptoms include these:
- Fear of germs or contamination
- Unwanted forbidden or taboo thoughts involving sex, religion, or harm
- Aggressive thoughts toward others or self
- Needing symmetry or a perfect order
Compulsions are repetitive behaviors that a person with OCD feels the urge to do in response to an obsessive thought. Common compulsions include these:
- Excessive cleaning and/or handwashing
- Ordering and arranging things in a precise way
- Repeatedly checking on things, such as whether the door is locked or the oven is off
- Compulsive counting
Not all rituals or habits are compulsions. Everyone double checks things sometimes. Generally, OCD differs from ordinary habits in these ways:
- Lack of control over thoughts or behaviors, even when they are recognized as excessive
- Spending at least one hour a day on the thoughts or behaviors
- Lack of pleasure in the behaviors or rituals, but their performance may bring temporary relief from anxiety
- Significant problems in daily life due to the thoughts or behaviors
Symptoms may come and go, ease over time, or worsen. People with OCD may try to help themselves by avoiding situations that trigger their obsessions, or they may use alcohol or drugs to calm themselves. Although most adults with OCD recognize what they are doing doesn’t make sense, some adults and most children may not realize that their behavior is out of the ordinary. Parents or teachers typically recognize OCD symptoms in children.

When to see a doctor
If you think you have OCD, talk to your healthcare provider about your symptoms. If left untreated, OCD can interfere in all aspects of life.
Treatment
OCD is typically treated with medication, psychotherapy, or a combination of the two. Although most patients with OCD respond to treatment, some patients continue to experience symptoms. Sometimes people with OCD also have other mental disorders, such as anxiety, depression, and body dysmorphic disorder, in which they mistakenly believe a part of their body is abnormal. Consider these other disorders when making decisions about treatment.
Psychotherapy
Certain types of psychotherapy, including cognitive behavior therapy (CBT) and other related therapies (e.g., habit reversal training), can be as effective as medication for many individuals. Exposure and response prevention (EX/RP) is a type of CBT. It involves putting the person in a triggering situation (e.g., touching dirty objects) but prevents him or her undertaking the related compulsion (e.g., handwashing). It is effective in reducing compulsive behaviors, even for people who do not respond well to medication.
