Background: The gut microbiome is emerging as an important factor in regulating mental health yet it remains unclear what the target should be for psychiatric treatment. Investigators aim at elucidating the complement of the gut microbiome community for individuals with Major Depressive disorder (MDD) and Bipolar disorder (BD) relative to controls, and test for relationships with symptoms.
Methods: Investigators prospect to recruit subjects including patients and controls amount to 240. All subjects will be collected for blood and stool samples,assessed by clinical scales. Finally, analyzing the correlation among the metabolon in blood, microbiota in stool and clinical scales to obtain the possible interaction between diseases and gut microbiota.
Full description
Background: MDD (Major Depressive disorder) and BD (Bipolar disorder), whose specific pathogenesis is still unclear, are both a multi-factorial disease being caused by biological, psychological and social factors. Accumulating evidence suggests that gut microbiota play an important role in brain functions and in the pathogenesis of neuropsychiatric diseases, such as autism, anxiety, as well as depression. No study has thus far compared the human gut microbiota among BD, MDD and the healthy control (HC). The aim of this study is to compare the composition of fecal microbiota among BD, MDD and HC. Furthermore, investigators aim at identifying direct correlations between human fecal microbiota (as a proxy for gut microbiota) and symptoms.
