Is it not just that diagnosis is better these days. I was at school in the 80s/90s. I struggled hugely with maths to the point it was like a foreign language to me. I was an A grade english student bright and articulate but I could not comprehend simple maths, I still can't. I failed maths gcse twice. Not a profound difficulty but I sat in class unable to understand anything. I'm pretty sure if I was at school now there would have been some kind of support maybe even a diagnosis.
Times have changed, we are far more aware of difficulties that were once ignored. Children were considered odd, badly behaved, stupid. Thank goodness we have moved on. So are there more children with issues or are they just diagnosed more now?
To be honest I am thankful that there is more diagnosis as my teenage son is on the autism pathway at the moment. We are very fortunate that he is not profoundly affected but life can be difficult at times. I feel plenty of guilt about lots going on in his life but I don't feel guilt for getting him immunised.
