Research Participant Registry Core

1. Infant Siblings of Children with Autism


The Infant Brain Imaging Study Network (IBIS) studies infant siblings of children with autism. They discovered three brain differences that predicted which of the infants would later be diagnosed with autism. This knowledge could be used to link such brain differences to behavior that is linked to autism, again helping to identify very young children at high risk of the disorder. The IBIS Network includes scientists at the University of Washington in Seattle; Children’s Hospital of Philadelphia; the University of Minnesota; New York University; and the University of Alberta, and McGill University in Canada will also take part in the study.
