Overview
Causes
Psychological
As a part of evolution, different species have grown to safeguard themselves by gathering/ hoarding food and constantly check for the threats around them. These evolutionary traits being passed on from generations may have a psychological cause for OCD. [1]
Biological
Abnormalities with the neurotransmitter serotonin has been linked to OCD. It is hypothesized that the OCD sufferers may have relatively understimulated serotonin receptors. This suggestion is supported by 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 available to the serotonin receptors. [2]
