Although there is a great deal of attention being directed at autism, mostly through the efforts of the growing numbers of families affected by this diagnosis, there is little mention about the growing number of children with a dual diagnosis in families whose children were born with Down syndrome.

If you are the mom of a beautiful child with Down syndrome who does not seem to be developing like other children with DS that you have met, who stops developing in what you expected to be a natural progression, or whose development turns around or changes in an alarming way, you may be wondering if he or she is facing another challenge besides Down syndrome.

Resources and support are available for families whose children with Down syndrome do have an autistic spectrum disorder in addition to garden variety DS. Concerned medical professionals and parents just like you have developed these resources and are available to answer some of your questions and share your concerns. I will list a few of these below.

Although no one wants to hear that their loved one faces greater challenges, it is important that a child with a dual diagnosis has the greatest opportunity for accommodations and support, and that families learn how to best support and encourage their children as they grow.

Know that you are not alone, as you will discover when you investigate the resources below that include Disability Solutions newsletter, the Kennedy Kreiger Institute, and other online support and information sites.

Families raising children with the dual diagnosis, or who suspect their son or daughter with Down syndrome might have an autism spectrum disorder, are invited to participate in online discussion groups for sharing information and support.

Browse at local bookstores, public libraries and online retailers for books about children, teens and adults with autism, like Outsmarting Explosive Behavior: A Visual System of Support and Intervention for Individuals with Autism Spectrum Disorders by Judy Endow and Engaging Autism - Helping Children Relate, Communicate and Think.
