It is thought that a combination of genetic and environmental factors can contribute to OCD.
Genetic Factors - Many people with OCD have one or more family members who also have it or other anxiety disorders influenced by the brain's serotonin levels. Because of this, scientists believe that the tendency for someone to develop a serotonin imbalance that causes OCD can be inherited.
Environmental / learned behaviors – OCD may develop as a result of learned behavior, either by direct conditioning (e.g. developing a washing compulsion after contracting a disease from contact with an animal) or learning by watching the behavior of others, e.g. parents.
Other factors that may increase the risk of developing OCD, include family history, social factors and psychological factors.
