My son had a friend in high school (1 year younger - they met on the track team) who had Asperger's. As a child, I guess he spent many hours under the desk at school (this I got from the coach). By high school, he was certainly socially awkward and misread many social cues. He was big into video games and often spoke in "game-speak" which baffled anyone who wasn't a gamer, and of course he never realized why people were not responding.
His parents may have gotten him some therapy, I don't know. But they were extremely supportive and at all the track meets. We watched this kid really blossom and build friendships in a team atmosphere where everyone was supporting every athlete. That's the thing about track and cross country - most anyone can run or throw heavy things (shot put, discus, etc.) and what was drilled into them is that your main competitor was yourself. Your job was to do better than you did the last time - run faster, jump higher, throw farther. That's all. The top runners stood at the finish line and clapped and yelled for the slowest kid. So it was a great environment for everyone, regardless of what was holding them back socially or athletically.
I still remember this boy getting confused about the start of a race, and 3 older boys (my son included) running to his gym bag, getting his spikes and screwing them into the bottom of his shoes so he'd be properly equipped. They jeopardized their own standings by working on his behalf. With seconds to spare, all 4 boys got to the starting line. The parents were in tears.
They also elected this boy as one of the co-captains, not out of pity, but because he was actually a motivator for others. He went on to a great college and made a lot of friends who ignored or celebrated his oddities.
We're also seeing an increase in many of these conditions, partly because of diagnosis changes and screening, and partly because of epigenetic changes in our cell functions due to a whole host of things. Epigenetic advancements have shown us that many things affect the operation of our cells through gene expression, but also that, while these changes are heritable, they are also not written in stone as genetic issues are. So a lot of things we say are "genetic" or "due to bad genes" actually can be influenced and repaired by epigenetic nutrients.
So, while it seems that "everyone has something", it's not that it can't be changed and improved in many cases. But I do think that an awareness of individuality and an acceptance of people's personalities and quirks is the first step in a better society for all.
