Obsessive-Compulsive Disorder Clinical Trials

Obsessive-Compulsive Disorder (OCD) is a mental health disorder in which people have recurring, unwanted thoughts, ideas or sensations (obsessions) that make them feel driven to do something repetitively (compulsions). The repetitive behaviors can significantly interfere with a person’s daily activities and social interactions. 


People with this condition may be aware that their obsessions and compulsions are senseless or unrealistic, but they cannot stop them. These obsessions can be very exhausting and time-consuming. If you are experiencing these symptoms, you may be eligible for a no-cost clinical trial. To find out if an OCD clinical trial is enrolling near you, select from one of our locations below.

More About Obsessive-Compulsive Disorder

About 3.3 million adults and about 1 million children and adolescents in the U.S. have OCD.

The disorder usually first appears in childhood, adolescence, or early adulthood. It occurs about equally in men and women, and affects people of all races and socioeconomic backgrounds.


Although the exact cause is not fully understood, studies have shown that a combination of biological and environmental factors may be involved. In addition, there is evidence that OCD symptoms can sometimes get passed on from parents to children.


There are environmental stressors that can trigger OCD in people who have a tendency toward developing the condition. Certain environmental factors may also worsen symptoms. These factors include: abuse, changes in living situation, illness, death of a loved one, work or school-related changes or problems and relationship concerns.


There is no lab test to diagnose this condition. The doctor bases his or her diagnosis on an assessment of the patient’s symptoms, including how much time the person spends performing ritual behaviors.


OCD will not go away by itself, so it is important to seek treatment. The most effective approach for treatment combines medications with cognitive behavioral therapy.
