My DH has Aspergers, he was born in 1960.
He was (to quote his mother) 'a funny little boy, we didn't know what to do with him so we sent him to boarding school.'
The sort of boarding school where 7 yr old boys who lose at a football match are sent to bed with no supper.
He has a recently dx walnut allergy.
He now runs an international biz, which he set up himself, employing 30 people on several continents.
We had severe asthmatics, a few dc with ezecma, some with food intolerance one that was 'slow' - later dx with dyslexia and sent to a brilliant dyslexic school.
I even knew of someone with autism in the early 80's.
There was a local 'institution' for adults where I lived, lovely blokes mostly, that used to do no harm. My mother horrified me telling me that some of them were 'in there' just for continence/mild behaviour issues and their families ought to be ashamed of themselves for sending them away. So I made an extra effort to be nice after that.
But given that 2 of my best playmates when I was growing up had DS, I think perhaps my mother was a little more openminded than most.
