The study found that children with past caregiving disruptions showed higher levels of symptoms.
"One common reason children show up at doctors' offices is intestinal complaints. Our findings indicate that gastrointestinal symptoms in young children could be a red flag to primary care physicians for future emotional health problems.
"Our study is among the first to link disruption of a child's gastrointestinal microbiome triggered by early-life adversity with brain activity in regions associated with emotional health," said Bridget Callaghan, postdoctoral candidate at the varsity.
For the study, 115 children adopted from orphanages or foster care homes on or before approximately they were two years old and 229 children raised by a biological caregiver were analysed.
"It is too early to say anything conclusive, but our study indicates that adversity-associated changes in the gut microbiome are related to brain function, including differences in the regions of the brain associated with emotional processing," said Tottenham.
Although more research is needed, this study helps to fill in an important gap in the literature, the team noted.
