The client's mother had OCD which is the aspect of the client's history that was the most likely contributor to its etiology.
OCD has a hereditary component as well; there is a 4–8% probability that a biological parent who has the disorder will pass it on to their offspring. A family history of another anxiety illness, such as social anxiety disorder or a phobia, might make someone more susceptible. Your chance of acquiring OCD might rise if your parents or other family members suffer from the condition.
According to some studies, there may be a genetic-environment interaction that puts the offspring of OCD parents at a greater risk for developing anxiety, OCD, OCD-like illnesses, or behavioral issues. In spite of the fact that not all children whose parents have OCD do, the sensitivity to developing it is probably heritable.
