  1. I wonder, how did the researchers from years ago make the leap to suggest that lack of serotonin was the causative issue in the first place? I'm assuming original data suggested a lack of serotonin or 5HIAA? Or was essentially an "assumption" made that led researchers down the lack of serotonin path?
