Answer 2

Answer:

The exact cause of OCD is unknown, but researchers believe that certain areas of the brain may not respond normally to serotonin, a chemical that some nerve cells use to communicate with each other.

Genetics are thought to contribute to OCD, as well.

If you, your parent, or a sibling have OCD, there’s about a 25 percent chance that another immediate family member will have it.
