Hi Emmy,
My name is Joy and I am married to an ADD guy. Both my sons (from first marriage) have Asperger. both his children from his first marriage have ADD aswell. I am the only true nutcase without an official diagnosis in our family....
As far as I can tell it's two different things. My sons both have ADHD too. So they are impulsive and hyperactive and get rit of a lot of energy that way.
My husband is the complete oposite of that. he seems passive, quiet and lacks initiative. He is tired a lot and is only very hyperactive in his brain. He tells me his mind keeps racing along and he is unable to get a grip on things: unorganized, forgetfull that sort of thing. my experience is ADD people do not have that many impulses...
So I think people with ADHD can vent their energy in their being active physically and people with ADD can't.
Both have the same chaotic mind which can never be stopped.
All I can say is we see the strong points in every family member and have so much fun together! dinner time in our house is very very interesting.
I recently started a blog about my experiences with my great Asperger kids. I think it is time for some positive sounds in the world of autism!
Hope to meet you there! Joy
