Interesting article about "four core subtypes" of autism

https://www.thetransmitter.org/spectrum ... -subtypes/ - Untangling biological threads from autism’s phenotypic patchwork reveals four core subtypes. Fragment:

My opinion: I think that part of individual diagnosed with autism spectrum disorder have pervasive developmental disorders not related etiologically and phenotypically to classic autism, especially the subtype of a "group specifically experiences social challenges and disruptive behavior", which tends to be somewhat described in articles like Asperger's 1944 article summarized and Straight talk about Asperger syndrome - the "Asperger's group". The subtype which "shows developmental delay and difficulties in select traits" may be associated with many cases of PDD-NOS diagnosed by earlier DSM-IV and "the largest group - consisting of 1,976 people - shows mild challenges in core autism traits" appear to have relatively mild form of classic autism which could be misdiagnosed as Asperger syndrome instead of autistic disorder using DSM-IV. "Asperger's group" appears to be on the schizophrenia spectrum since childhood (so-called "schizoid disorder of childhood" and may be especially prone to schizotypal disorder), but it is still a pervasive developmental disorder and a kind of autism, not just a personality disorder.

I'm really sorry, I tried to digest what you wrote but I can't, for the life of me, understand.

Why does the website hosting the article have one set of writing standards for scientists and another set for journalists?

Hmm . . . this means something . . .

The way they are dividing up autism into subtypes is a bit like dividing people up according to whether they like ham or cheese. One subtype of humanity enjoys both ham and cheese, one subtype leans towards ham, one leans towards cheese, and a smaller group hates both.

So yeah... I guess we could do all these tests to work out which subtype someone is in, and then we could, I don't know, either feed them only cheese because that's what they like, or try feeding them ham, to make them more like everyone else?

Maybe they'll get somewhere with all this subtyping eventually, but there's nothing useful yet.

Spectrum was good but then it became The Transmitter and since then there hasn't been much deep discussion of issues relevant to us (actually autistic people), it's mostly academic navel-gazing.

I noticed that some autistic people do not have many traits associated with "classic autism" described by Leo Kanner, among absent traits there may be: speech delay, need for sameness and predictability, good visual thinking with poor verbal thinking. I also think that some cases of ASD are associated with comorbid schizoid personality disorder or schizotypal disorder which is "melted" into individual's autism (these schizophrenia-spectrum disorders may will have more symptoms in early adulthood than in childhood or adolescence), probably only minority of ASD individuals have comorbid schizophrenia-spectrum disorder, but prevalence of SSD among autistic people may be many times higher in the general population and may account for many cases of poorly-functioning ASD individuals in adulthood, I even postulate specific type of ASD which I would call "schizodevelopmental autism" which may be especially dissimilar to the stereotypes about autism based on Kanner syndrome. Some cases of ASD would be classified as Kanner syndrome earlier, some are markedly similar to Kanner syndrome and some are more dissimilar to it, but even these dissimilar cases are still cases of autism and pervasive developmental disorder. Schizoautistics would require larger support than standard (not comorbid with SSD) autistics with the same level of intelligence quotient and functional language. They are doubly challenged in life - firstly due to ASD, secondly due to SSD.
