Why obsessive-compulsive disorder, an anxiety based disorder, develops isn't fully understood. Some theories include both our biology and our environment.
Biologyo There is some indication that OCD may be caused by changes in brain chemistry or brain functions. It seems that Serotonin is involved since SRIs, which increases the levels of available Serotonin, are effective in dampening symptoms o Included in this theory is the possibility that OCD has a genetic component, but the specific genes involved have not yet been identified. For example, in some cases OCD is associated with Tourette’s Disorder, which does appear to have strong heritability. Twin studies also provide strong support for the inheritability of OCD
Environmento Sometimes OCD begins with a response to an identifiable stressor. For example, compulsions to wash hands may follow contact with foul substances. Sometimes it can be difficult to recall the initial incident, especially if the behaviour has been a long standing patterno Behaviours that you may have seen modelled or behaviours established your self seem to contribute to the development of OCD o Stress appears to worsen OCD symptoms but it does not seem that stress itself causes OCD
However OCD is caused, it can leave individuals feeling ashamed and frustrated. If you experience frequent and uncontrollable, obsessive thoughts and compulsive behaviours see your doctor or contact a psychologist to help change this pattern.
