Obsessive-Compulsive Disorder (OCD)

What Is Obsessive-Compulsive Disorder (OCD)?

People with obsessive-compulsive disorder (OCD) experience obsessions, compulsions (also known as rituals), or both.

• Obsessions are recurrent and persistent thoughts, urges, or images that are intrusive and unwanted. They usually cause substantial anxiety or distress. People with OCD try to ignore or suppress the thoughts, urges, or images, or to neutralize them by performing a compulsion (also called rituals). Examples of OCD obsessions are intrusive thoughts about harm occurring to someone or worries about becoming contaminated.
• Compulsions (rituals) are excessive repetitive behaviors or mental acts that the person feels driven to perform in response to an obsession. They're intended to decrease anxiety or distress, or to prevent something bad from happening. Examples include excessive handwashing, checking, or counting.

For example, a person with OCD may obsess about becoming contaminated with dirt or germs and wash their hands excessively in response. Or they may worry that the house will burn down so they feel compelled to check the stove 30 times to be sure it’s off before they leave the house.

Obsessions or compulsions are time-consuming or cause significant distress or impairment in functioning.

How Common Is OCD?

OCD is common yet often under-recognized. In any one-year period, it affects about 1% to 2% of the population.

Who Gets OCD?

Anyone can get OCD. This condition occurs around the world. It affects both males and females and people of all ages, races, and ethnicities. OCD often starts during late adolescence.

How Serious Is OCD?

OCD varies in severity and can be quite severe. It can cause substantial suffering and often makes daily activities difficult. However, effective treatments are available.

What Treatments Work for OCD?

1. Medications called serotonin reuptake inhibitors (also known as SRIs, or SSRIs): These non-addicting, widely prescribed medications help stop obsessive thoughts and compulsive behaviors. They also often alleviate depression, anxiety, and other symptoms. They're usually well tolerated and are not habit forming. Often, higher doses are needed than are typically used for other conditions such as depression or anxiety. Other medications may also be helpful when added to an SRI.
   
   The SRI medications are fluoxetine (Prozac), sertraline (Zoloft), escitalopram (Lexapro), paroxetine (Paxil), fluvoxamine (Luvox), clomipramine (Anafranil), and citalopram (Celexa). These medications' brand names, which are in parentheses, may differ in different countries.
2. Cognitive-behavioral therapy (CBT): CBT is a "here-and-now" practical treatment that helps change problematic OCD thoughts and behaviors. Exposure and response prevention (ERP) is a form of cognitive-behavioral therapy that focuses on OCD compulsions and avoidance behaviors. It helps people gain better control over their repetitive behaviors (compulsions) and feel more comfortable when in a situation that usually triggers their obsessions (for example, dirt for someone with contamination obsessions).

Medications and CBT are effective for a majority of people with OCD. These treatments usually improve OCD obsessions and compulsive behaviors, and they also often help people feel less depressed and anxious. Some people improve when they're treated with an SRI alone or with CBT alone, whereas others benefit from receiving both treatments at the same time. For more severe symptoms, treatment with both medication and CBT is usually recommended.

What Causes OCD?

OCD likely results from a complex combination of genetic predisposition/neurobiologic factors as well as life experiences and sociocultural factors.

Hope for People with OCD

OCD can be severely distressing and impairing. But there is hope for people with OCD! Recommended treatments help a majority of people get better.
