MINDDful-XD research study


This study aims to figure out the connection between the digestive system and some brain-related conditions. The tiny organisms living in our digestive system, called gut microbiota. The gut microbiota might be linked to some brain-related conditions such as Autism, Attention Deficit Hyperactivity Disorder (ADHD), Obsessive Compulsive Disorder (OCD), and Tourette Syndrome (TS).

These conditions can be affected by both our genes and things around us in other words our environment. The gut microbiota can affect how our immune system grows. It also affects how our brain develops and functions. This is through a pathway called the gut-brain axis. Our team aims to see if there's a link between these conditions and the gut microbiota. We hope this research will lead us to new ways to support children and their families.
