Yes. I think you’re right. It’s also that the diagnostic criteria focus on ‘is this child typically developing’ and not ‘is this child disabled’?
Our DS4 was referred to occupational therapy by his nursery due to sensory issues. I was worried because DS7 is autistic and had so many issues when he got to school, so I sent DS4 to a neurodevelopmental assessment on my DH’s health insurance ‘just incase’. My DS4 now has an autism diagnosis with the suggestion he could pick up an ADHD one later.
No professional has questioned his autism diagnosis, because he ‘does all the autisms’. He has full body stereotypies, speaks in a patchwork of echolalia and terrible grammar, etc. However, the assessment process doesn’t actually check his social communication ability beyond ‘does he make ‘enough normal’ eye contact?’ And ‘is his speech similar on a granular level to a typically developing child?’
This is how my extrovert DS4, who has loads of friends and the charisma of a TV shopping channel presenter, is nonetheless diagnosably autistic. On paper, he appears ‘severely disabled’ because he is literally a tickbox of ‘all the autisms’: 15 pages of all the ways his behaviour suggests atypical development. In practice, he hates sirens, hand driers and children crying loudly, can’t sit still and that’s… about it, really. He’s so extrovert that he managed to make a friend during his school reception taster - I think most of the NT kids didn’t manage that!!
We had his council OT assessment yesterday and almost every single adjustment is to help our DS4 sit still in class - something he wouldn’t have needed to do as, say, a shepherd. The comment we get most about DS4 is not ‘he’s socially awkward’, it’s ’wow, he’s very busy/wriggly, isn’t he? He must keep you on your toes (nervous laugh)’
There’s no way DS4 would have got a diagnosis even 20 years ago. Not because DS4 doesn’t need support - he will need a fat pencil, ear defenders, movement breaks, sensory putty and a wriggle cushion for school - but because he has no resemblance to the social stereotype of (male) autism. He’s just a very fidgety, noisy-adverse DS who hates saying ‘good morning’ to adults (he’s fine exchanging enthusiastic fart noises with other kids)!!!
I think there are an increasing number of kids getting autism diagnoses who are like my DS4. Kids who need adjustments to perform well in school (e.g. a desk at the quiet end of the classroom) who would have struggled unnoticed, or been punished for fidgeting/being a bit weird, a few years ago. This isn’t an ‘autism epidemic’ caused by chemicals/vaccines/SSRIs/older parents/premature birth - it’s a trend of better identifying and labelling kids who need the extra help because their brains work slightly different from average.
