  8. 8.  Cause for OCD is often liked with neurotransmitter Serotonin Role of serotonin is to send chemical messages from one neuron to another OCD suffers may have damaged receptor sites that prevent serotonin from proper functioning Possible genetic mutation or gene disorder
  9. 9.  Although OCD appears to be fairly common, it is often misdiagnosed by doctors On average, patients wait 9 years from onset of symptoms to participating in effective treatment Sometimes confused with OCPD
