Causes of OCD

In the early 1910s, Sigmund Freud attributed obsessive–compulsive behavior to unconscious conflicts which manifested as symptoms. Freud describes the clinical history of a typical case of "touching phobia" as starting in early childhood, when the person has a strong desire to touch an item. In response, the person develops an "external prohibition" against this type of touching. The cognitive–behavioral model suggests that compulsive behaviour is carried out to remove anxiety-provoking intrusive thoughts. Unfortunately this only brings about temporary relief as the thought re-emerges. Each time the behaviour occurs it is negatively reinforced by the relief from anxiety, thereby explaining why the dysfunctional activity increases and generalizes (extends to other, related stimuli) over a period of time.

OCD has been linked to abnormalities with the neurotransmitter serotonin , although it could be either a cause or an effect of these abnormalities. Serotonin is thought to have a role in regulating anxiety. To send chemical messages from one neuron to another, serotonin must bind to the receptor sites located on the neighboring nerve cell. It is hypothesized that the serotonin receptors of OCD sufferers may be relatively understimulated. This suggestion is consistent with the observation that many OCD patients benefit from the use of selective serotonin reuptake inhibitors (SSRIs), a class of antidepressant medications that allow for more serotonin to be readily available to other nerve cells.
