I found this post by a self-confessed Asperger’s sufferer really interesting, though I’m not sure I understand it all. Here’s a snip:

I believe it runs in my family somehow, but I got all the negative aspects of it. My oldest brother has an extremely high IQ, my youngest brother has an incredible capacity for creativity. My middle brother has a unique ability to spot anything different that most human eyes overlook. For example, standing in a yard of clover, he will find every 4-leaf clover there is to find in record time. Me? what did I get? The famous autistic traits of inability to connect to others and obsessive compulsive disorder. Break my routine and I throw a fit. Take me to a public place and I spaz out. My family chalked it up to extreme shyness. Some doctors said it was depression or ADD. I’ve even been asked repeatedly if I’ve ever been abused. Even when my elementary school teacher showed concern because I was more involved with organizing the pencils on my desk in a certain order than I was with participating in class, my parents chose to ignore the signs, whether out of fear or ignorance I dont know. Even if they hadn’t ignored the signs, what could they really do? What I do know is that, yes, I love my family very much. However, I do not have a connected feeling with anyone on the planet.

She ends by endorsing a possible cure or therapy for allergy-related autism.
