I would like to make the following observations based on the above-mentioned study, which I believe is a very important insight into the microbe and mental health.
This study shows that chronic stress decreases Microbiome diversity
In addition to the stress-induced changes in the Microbiome, the rats also began experiencing loss of pleasure and “despair-like” behavior.
And…. what is really fascinating is that when these microorganisms were transferred from the stressed rats to a new group of animals that had not been stressed, Dr. Emily Jutkiewicz found that these new animals also began to demonstrate these same behavioral changes after 5 days, suggesting a potential causal mechanism. (i.e.…the changes in the Microbiome are causing the behavioral changes)
In human studies…similar changes in the Microbiome are found in people with bipolar disorder and major depression…resulting in high anxiety, sleep problems and increased incidence of other general health problems.
