Low serotonin levels have traditionally been suspected as playing a role in depression, but there has been little solid evidence to support this hypothesis. Consequently, scientists have been increasingly moving away from the low-serotonin theory and looking instead at other possible causes of depression, such as the relationship between stress and inflammation and other environmental factors.
Last September, Medical News Today reported on a study published in ACS Chemical Neuroscience that found no difference in behaviors between mice that lacked serotonin and a normal group of control mice.
From this finding, the researchers behind that study - from Dingell VA Medical Center and Wayne State University School of Medicine, both in Detroit, MI - concluded that serotonin may not be a dominant factor in depression. Instead, they suggested that risk for the condition may instead be comprised of a range of different factors.
