What is the definition of obsessive compulsive disorder?

Obsessive-compulsive disorder (OCD) is a mental illness that causes repeated, unwanted thoughts (obsessions) and behaviors (compulsions). The obsessions are often accompanied by anxiety, and the compulsions are often performed in an attempt to reduce the anxiety.

OCD is a common disorder, affecting about 1% of the population. It usually begins in adolescence or early adulthood, and it can be chronic.

OCD can significantly impact a person's life, causing difficulty at work, school, and in relationships. However, OCD can be effectively treated with therapy, medication, or a combination of both.

OCD is characterized by the presence of obsessions and compulsions.

Obsessions are:

- Unwanted and intrusive thoughts, images, or urges

- Often repetitive and distressing

- Can cause anxiety, fear, or disgust

- May be difficult to control or stop

Compulsions are:

- Repetitive behaviors or mental acts that a person feels driven to perform

- Often performed in an attempt to reduce anxiety or distress

- May be excessive or unreasonable

- Can interfere with a person's daily life

OCD can be a disabling disorder, but it can be effectively treated. Treatment options include cognitive-behavioral therapy, medication, and a combination of both.
