There is a Yahoo group with exactly the right profile:
The Down Syndrome & Autistic Spectrum (ds-autism) listserv was
created so families, parents, and professionals interested in this

The main author, Professor Patricia Howlin, is based at the Psychology
Department of St Georges Hospital Medical School. The web site of the
Surrrey Branch of the National Austistic Society mentions her name in
a list of specialists to whom parents of autistic children can turn
for diagnosis and second opinions. The list is reasonably current, as
it was last updated on August 11, 2003.
Patricia Howlins contact details (tel, fax, email) on the St Georges

One mother has found that riding helps her daughter a lot:
Stacy Beall has watched her daughter Elizabeth, who suffers from
Downs Syndrome and autism, grow thanks to therapeutic riding.
"I can't say enough good things about the program," says Elizabeth's
mother, Stacy Beall. "They individualize a program for each rider,
according to their abilities, and tune it to help the rider gain the
greatest benefit. It has really made a difference for my child." Beall
stands outside the ring, watching her daughter with obvious pride.

I thought you might be interested to read about Glen Sheppard, a
23-year-old Australian who has both Downs Syndrome and autism. He has

For general support, you might also wish to contact the South West
Thames Branch of the Downs Syndrome Association, which covers West &
South West London, Surrey & West Sussex. This group might know if
there is someone near you in a similar situation.
I hope this is the sort of information you are seeking. Please request
further clarification if required (I am away Friday-Monday).
I sincerely hope you will find the support and knowledge you need to
help your son live life to the fullest.
