Causes

It is found that OCD runs in some families, though there is no definite cause behind it. However, there are theories that attempt to explain the what may be the cause.

GENETIC/CHEMICAL

LEARNING THEORY

Learning theorists believe that OCD could be the result of learned habits that are acquired by observing and repeating what is around.

Some researchers believe that OCD could be a result of an offset in the body's natural chemistry or brain functions, like a decrease in serotonin levels. Some believe that there may be a genetic component, but no specific genes have been found responsible.
