Obsessive-compulsive disorder
Recognizing signs of obsessive-compulsive disorder and ways to get help
Obsessive-compulsive disorder (OCD) is an often-misunderstood mental health condition. People sometimes use terms like “obsessed” or “obsessive” casually. They may use these words when they double-check that the stove is off or that doors are locked. However, OCD is a serious illness with repeated, unwanted and unpleasant thoughts. People with OCD also may feel the need to do the same things over and over again, even though they don't want to.1

What is OCD?
OCD is defined as a disorder that causes someone to have a pattern of unwanted thoughts, engage in repetitive behaviors or both, making it hard to do everyday activities.2 OCD affects 1–2% of the U.S. population.3
What causes OCD?
The exact causes of OCD are not fully understood. Several factors may raise the likelihood of developing the disorder.2
- Biology: Brain imaging has shown that people with OCD may have differences in parts of the brain. These areas of the brain are related to behavior and emotional responses.
- Childhood trauma: Some studies show a link between childhood trauma and OCD symptoms.
- Genes: Research suggests there may be a family connection to OCD. If a parent or sibling in your family has OCD, you may be more likely to have it too.
What are the common symptoms of OCD?
OCD symptoms may start slowly and can get better or worse over time. OCD can cause unwanted thoughts or obsessions. These thoughts may cause repetitive behaviors or compulsions. Some people with OCD have tics involving repeated movement or sounds.2 It is also common for people with OCD to be diagnosed with an anxiety disorder.
