The ability of the brain communicate with the gut microbiota is emerging as an exciting and promising concept in modulating health. The Brain Gut Foundation aims to promote and evaluate scientific research on the study of the microbiome-gut-brain axis. Treatments of children and juveniles can be more effective using scientific knowledge of the brain – gut relation. The foundation, is being supervised by a Scientific Council to ensure academic rigour. The data are obtained by clinical child neuropsychologists and other experts following a standardized protocol. The brain-gut assessment protocol as well as the treatment are (partially) subsidized by the Foundation.
