Quick question

Posted by ImInterested on 12 Aug 2009 at 17:27 GMT

I believe that we don't know that a low serotonin level can CAUSE depression but isn't it established that depressed persons have generally a lower serotonin level? I know correlation is not causation just want to know that...

Thank you very much!!
