He should be able to understand in simple terms. Give him a basic explanation of your hydro and tell him that it makes your brain work harder to do certain things. That'll satisfy his curiosity for the moment, and as he gets older, his questions will be more sophisticated and involved. Just follow his cue and take them as they come. :)

LIZARD :)

Hoosier Mom's advice is good, she is talking about behavior mod. Ask your son's teacher about what approach they use in the classroom. (I once worked in class of Autustic children and there are so many degrees and behaviors.) It must be very hard for you. Is there an autism society near you? The ones in NJ (Where I once lived and worked in) offer respite care.
I can't imagine how hard it must be.

my daughter is 10,but she was 8 when my ms first started. She took it pretty hard when I first started getting sick. But with learning about ms,and have her concerns answered,it took a big weight off her shoulders.
Now on the other hand my boy is 5 now,but was 3 when it started,he knows that mommy is *sick*,but that is all he knows. but neigther one of them can take it when im a flare,or having bad ms days.
The worst thing for my daughter to get over is my memory problems. As it interfears in her school,and after school things. I cant remeber when and where she is suppose to be. And that is probably the worst thing for me too.
I hate the fact that my 10 year old has to be my memory help,but shes good at it for now.
