Obsessive-Compulsive Disorder (OCD)

Obsessive-compulsive disorder (OCD) is a condition in which you have frequent unwanted thoughts and sensations (obsessions) that cause you to perform repetitive behaviors (compulsions). The repetitive behaviors can significantly interfere with social interactions and performing daily tasks.

OCD is usually a life-long (chronic) condition, but symptoms can come and go over time.

Everyone experiences obsessions and compulsions at some point. For example, it’s common to occasionally double-check the stove or the locks. People also often use the phrases “obsessing” and “obsessed” very casually in everyday conversations. But OCD is more extreme. It can take up hours of a person’s day. It gets in the way of normal life and activities. Obsessions in OCD are unwanted, and people with OCD don’t enjoy performing compulsive behaviors.

What is the difference between OCD and OCPD?

Even though they sound similar, obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) are different conditions.

OCPD is a personality disorder that causes an extensive preoccupation with perfectionism, organization and control.

People with OCD are usually aware that their obsessions and compulsions are problematic and accept that they need professional help to treat the condition. People with OCPD usually don’t think there’s anything wrong with their behavior and beliefs.

Who does OCD affect?

OCD can affect anyone. The average age of onset is 19 years. About 50% of people with OCD begin to have symptoms in childhood and adolescence.

It’s rare for someone to develop OCD after the age of 40.

How common is obsessive-compulsive disorder (OCD)?

Obsessive-compulsive disorder is relatively common. It affects 1.6% to 2.3% of the general U.S. population.
