Once upon a time, there were simply naughty children, children who didn't fit in, children who were 'different' to all the others. Then one day, some scientist or other said "Hey, these food colourings, they make rats to funny things, maybe they do the same to children!" but by then all the naughty children had grown up and had their own children who were now allergic to E102 and E110. A few years passed and we realised that it wasn't food colouring at all, and infact it was ADHD and these children needed to be pumped full of Ritalin in order to keep them docile.
As the years passed, another generation has been spawned, and the cycle begins anew, only this time its autism, a catch-all phrase that covers a huge spectrum of development disorders, from social awkwardness through to non-verbalism, the range traits and symptoms is mind-boggling, and even today we don't know what the cause is, we dont know how to fix it, heck, we don't know what IT is.
The human brain is far too complicated for current medical science to fully understand, a slight chemical imbalance during development, is all it takes to throw a young brain out of whack. Give it a few years and something else will come along to explain why some children behave differently to others.
I turned 40 this year, I was diagnosed as being high functioning autistic almost a decade ago, do I care? not really, nowt I can do about it now. I have coping mechanisms in place that allow me to maintain a full and mostly happy life. I have a job, I have friends, I don't go out much but then I'm old enough to know better. I don't let it hold me back, but I am aware of it, and know that sometimes it means that I will misinterpret something important, or say completely the wrong thing. But what the hell, life's too short to worry.
