05 Jun 2019 --- Autism is linked to similar gene mutations found in both the brain and the gut, according to a new study from the Royal Melbourne Institute of Technology (RMIT) in Australia. The vast majority of people with autism suffer from gut problems and the reason behind this was, until now, unknown. The study findings confirm a gut-brain nervous system link in autism, opening a new direction in the search for potential treatments that could ease behavioral issues associated with autism by targeting the gut.
