A study looked at the connection between gut bacteria and depression and named the probable culprits for these mental issues. 🙇♀️ The researchers analyzed fecal microbiome in conjunction with diagnoses of depression in 1,054 people. They showed that two types of bacteria — Coprococcus and Dialister — were absent in the guts of those diagnosed with depression, even in those taking antidepressant medication.
In addition to this discovery, the team devised a technique allowing them to RANK the neuroactivity, or the bacteria’s ability to produce neuroactive compounds, of different human gut bacteria. 👩🏻🔬
This study allows us to identify different bacteria that may play a role in our mental states and gives us a new window into the connection between the gut and nervous system.
