Without wanting to sound provocative, it's really frustrating to hear about what neurodivergence is and isn't from people who aren't neurodivergent themselves.
Of course everyone is entitled to an opinion on any subject under the sun, but if you aren't neurodivergent you have no idea how it feels. It doesn't matter if you have neurodivergent family members, it's not the same as understanding it from the inside.
And it's frustrating to find other people deciding they know better than us.
So, so, so many posts on here bloody constantly from people who "know" kids at school who apparently got a diagnosis EASILY but DEFINITELY aren't ACTUALLY autistic. Because they can tell. Right 🙄
A diagnosis of autism, ADHD etc is often extremely hard to get. Every single SEN parent I know had to jump through hoops to demonstrate it wasn't their parenting. If there are any other factors which may be influencing the presentation, diagnosis is delayed.
I do agree that we need some way of differentiating between groups of autistic people where the degree of difficulties are different.
I'm autistic (and ADHD) and so is my DD. My DS is also autistic but at 14 years old, he's still in nappies. Although we all find similar things difficult, our ability to cope, mask, and manage is vastly different.
The thing is with neurodivergence, many of the difficulties are the same as what a neurotypical child might experience. The crucial difference is the degree to which it interferes with functioning and how many of these differences there are.
For example, noise. There are plenty of children who don't like loud noises, or lots of background noise. But they may not be as intensely bothered by it as an autistic child and it may not present with the whole range of other autistic symptoms too.
Research is currently indicating that there are structural differences in the autistic brain. I can't bloody wait until/if this reaches a threshold where it can be used reliably for diagnosis because it will put paid to all the threads trying to dismiss what autistic people are experiencing, living, and describing.
As for you OP, maybe your presentation at childhood wouldn't have met the threshold for diagnosis. Or more likely, you don't recognise autistic traits within yourself any more as you've crafted a life that works for you, and you manage to mask effectively.
I'm not trying to shut down conversation - I think it's helpful to have conversations about how we more effectively describe different groups. But pouring cold water on the diagnosis of autism, with a bunch of neurotypical people all agreeing that most of us who are diagnosed aren't actually autistic at all is really hard to read. Time after time after time after time.
