James Morton, Ph.D., discusses research on the gut-brain axis and the development of autism spectrum disorder (ASD). They explore the link between imbalances in the gut microbiota and ASD, analyze the gut microbiome during early childhood development, and discuss the challenges of educating therapists and parents on the gut-brain connection. They also examine the impact of stresses and disparities on the gut-brain connection, explore future research possibilities, and alternatives to fecal transplants for treating digestive disorders.
