PayItForward,

I really learned a lot about Autism while researching facts on
Humane treatment of animals & factory farming. Sounds like
quite a stretch does it? I discovered this author, Temple Grandin,
who is herself autistic, who also designs humane animal systems
for handling, restraining & reducing stress in animals bound for
slaughter. She is an expert in animal behavior. Her website is
http://www.grandin.com/

She wrote a paper for the Center For Study of Autism that is
very interesting. It also talks about several subtypes of Autism.
Asperger's Syndrome is included as one of these subtypes.

Here is a link to her paper;

btw, what type of help does your brother ask for, monetary or
just for sympathy(a shoulder to cry on) ?
