“It is possible,” the authors wrote, “that the signals the gut and its microbes get from the brain of an individual with a history of childhood trauma may lead to lifelong changes in the gut microbiome.”
It’s also possible — or even probable — that the relationship isn’t uni-directional. The researchers noticed that the people with altered microbiomes had differently shaped brains, too, suggesting that the impacted gut may have doubled back and impacted certain brain regions — though they noted in the study that they don’t have enough information to be sure that’s the case, and cautioned against leaping to conclusions.
