If you want to get the best knowledge and inside juice on AS and Autism, WP is THE BEST PLACE TO GO, no doubt about it. I reckon all people who want to work and/or diagnose AS should start here!
If I may ask, how old is your little brother? I'd like to know more about him. Y'know, what are his obsessions? His routines? What's his hair colour and the type of underwear he uses? (okay, cut out the last two!)
EDIT: I wondered his age, but that was answered in the other topic you made with the same title. (lack of creativity, eh? For shame!)

I was sad when I found that she left
But then I found
That I could speak to her,
In a way
And sadness turned to comfort
We all go there
