Obsessive-compulsive disorder (OCD) is a mental illness. It consists of unwanted, recurring thoughts (obsessions) and behaviors (compulsions). The person with OCD does not feel able to control this. It can disrupt daily functions.
The exact cause of OCD is not known. The nervous system, environment, and genes may play a role.
The genes that you inherit from your family may play a role in the development of OCD.
