Comparison of Gut Microbiota in Children with Autism Spectrum Disorder (ASD) and those Without ASD


The purpose of this research is to learn more about what makes up the gut organizations (stool and urine) in children with Autism Spectrum Disorders (ASD). This may help to understand more about what causes ASD, help with early detection of ASD, and identify children with ASD who might respond positively to popular dietary interventions such as the Gluten-Free Casein-Free diet.
