Half and half really. There were definitely kids that had ASD/ADHD back in my day when these things didn’t formally exist to diagnose. However, it was more ‘clear cut’ back then with people in ‘groups’.
-what was deemed classic autism back in the day, which was extremely obvious and those kids went to ‘special school’. Unfortunately back then special needs were not really differentiated and people didn’t want to understand. Our local ‘special school’ was called ‘Xxx School for the Retarded’ (that was its actual name and I have just identified it for privacy of location’. It had kids with both developmental and physical disabilities. So, for example, kids with cerebral palsy, who were completely capable of learning in a mainstream school were put there, lumped in with kids with classic autism and none of them were really taught anything.
-kids who were just ‘weird’ but not weird enough to be sent to the special school. They tended to be shunned and isolated due to behaviours, and were not given educational support they required, so literally shoved in a corner socially and educationally. Now we would support as ASD.
-kids who were ‘naughty’ or ‘didn’t pay attention’. They tended to just be punished, and often left school illiterate and innumerate, and went on to manual labour jobs. Now we would support as ADHD.
-kids who were quirky, but rubbed along socially (tended to find a similar quirky tribe) and educationally (some excelled, some didn’t), and generally left school to go onto uni or other work. Now we would support as ASD.
I think it’s the last two groups where things have changed. They were always group that just rubbed along at school and then in life to varying degrees. Now every second person is in these groups and society tells them all sorts of things because they are different. If you take people in my profession, looking at people my age, there would be LOTS of folk that would have been diagnosed as ASD if that had of existed when we were kids or even as adults starting a career. Most surgeons and anaesthetists of my generation would definitely have ramped it in. However, people just got in with it. I would say the incidence of people now coming through is the same, but the difference is they all believe they have something wrong with them, and have spent their lives to that point with everyone telling them they can’t just ‘get on with it’ but they need this, that, and the other to survive which has resulted in a self fulfilling prophecy and zero resilience.
The problem is also that the buckets have been screwed up so now everyone has ASD. I have a child who was diagnosed Asperger’s quite a while before it ceased to exist. All of their friends were also. Now they are told they have autism, and society now treats them as special needs. None of them believe it and all will tell you they don’t have autism. It’s not that they believe they are any better or worse than someone who does, just different. We have a close family friend with a (now adult) child with autism who can’t speak intelligibly, has severe behavioural issues, is not toilet trained and had to be institutionalised when old enough. My child doesn’t relate to this at all and does not believe they have the same thing (and yes, even taking the ‘spectrum’ into account). They consider it entirely different and believe it’s like someone putting people with asthma and people with diabetes together and saying ‘now you all have asthma’. I also believe if they had of been told and treated as though they had autism when diagnosed, none of them would now be as they are in life and certainly not doing the jobs they do. They would likely all be sitting in disability, believing they couldn’t do things.
