Imbalance in the digestive system may disrupt brain signals and influence behavioural symptoms in children with autism, according to a study on Monday.
Researchers from the University of Southern California (USC) demonstrated that gut metabolites impact the brain, and the brain, in turn, affects behaviour.
The study, published in the journal Nature Communications, adds to a growing body of science implicating the “gut-brain” axis in autism.
“The brain acts as the intermediary between gut health and autism-related behaviours,” said first author Lisa Aziz-Zadeh, Professor at the Brain and Creativity Institute at the USC Dornsife College of Letters, Arts, and Sciences.
