A little-known fact is that the divorce rates for parents with special-needs children is tragically high. According to the documentary Autism Every Day, the divorce rates for these parents soar to as much as 80 percent. A recent study in The Journal of Consulting and Clinical Psychology revealed that parents of a child with attention deficit hyperactivity disorder are nearly twice as likely to divorce by the time the child is 8 years-old.
And when I contacted various special needs organizations to get a figure, spokespeople were reluctant to set a figure, but acknowledged that it"s "very high."

Having a child with autism can put stress on the parents" marriage, and a frequently cited statistic leads to a common perception that the divorce rate among these families is as high as 80 percent. But a study to be released at a news conference today by researchers from Kennedy Krieger Institute in Baltimore found that a child"s autism has no effect on the family structure.
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.

Abstract
In this study, we examined the nature, timing, and correlates of divorce in families of children with Down syndrome (647), other birth defects (10,283) and no identified disability (361,154). Divorce rates among families of children with Down syndrome were lower than in the other two groups. When divorce did occur in the Down syndrome group, however, a higher proportion occurred within the first 2 years after the child"s birth. Mothers and fathers of children with Down syndrome were much more likely to divorce if they were younger, had not graduated from high school, and if fathers were less educated and lived in a rural area. Few effects on divorce were noted for a variety of family structure variables.
