Brian Freedman, PhD, lead author of the study and clinical director of the Center for Autism and Related Disorders at Kennedy Krieger Institute, said the findings seem to debunk a lot of the general understanding about high divorce rates among parents of children with autism. Dr. Freedman and his research team found that 64 percent of children with an autism spectrum disorder (ASD) belong to a family with two married biological or adoptive parents, compared with 65 percent of children who do not have an ASD.
