Children’s Autism Symptoms Reduced Nearly 50% Two Years After Fecal Transplant

Children diagnosed with autism who received a fecal microbiota transplant (FMT) had nearly 50% less severe autism symptoms up to two years later. Eight weeks after receiving a FMT, the severity of autism spectrum disorder (ASD) symptoms was 23% lower than at baseline, as assessed by the Childhood Autism Rating Scale (CARS).
