Tldr "The researchers found that certain regions of the cerebral cortex showed lower neuron density in autistic children than in controls. That means were there less brain cells in regions associated with memory, learning, reasoning and problem-solving.

On the other hand, the study found that the brains of autistic children had higher neuron density in the amygdala. A part of the brain’s limbic system, the amygdala is a small but critical structure with multiple functions. The amygdala processes emotions, and connects those emotions to tasks like learning, memory formation, and sensory processing. It’s also the home of the fight or flight response."

They also talk about how this doesnt mean a whole lot because autistics were faster at problem solving in previous studys.

I’m autistic and I think I’m faster at problem-solving because I use procedures I’ve stored in long-term memory, rather than fluid intelligence. I mimic fluid intelligence with extremely efficient sets of building blocks.

Kind of like a weak processor but a vast, well-indexed database of efficient solutions ready-made.

What a fitting username 🙂

What if these differences aren't the result of autism, but societal neglect as a result of autism?

Think about it. Increased flight/fight and less developed super imporant regions school is supposed to stimulate development in. It's like that basketball coach analogy. People don't waste time on those they don't believe in. Add in some bullying and voila. Perfectly adapted to the enviroment!

The result of societal neglect as a result of autism is a result of autism.

Like, there’s no perfect way to distinguish between those things.

The cause for developmental delays is different. One is direct, the other indirect and enviromental.

This just in: Neurodivergent people are neurodivergent

The same is going to be true for any population group that has hugely divergent cognitive needs or experiences. London taxi drivers have noticably different brain layouts.

Ok, but what type of autistic?

My brother and I are different types. He's super genius, and it's not Savantism. Crazy good physicist, but awkward.

My daughter is yet another. Smart, not like my brother but not an idiot. Absolutely all of hers is wrapped up in communicative and emotional disorders, with some associated tics and traits. She has to learn social interactions the hard way and still lives my mimic frequently.

I'm the one that was able to read body language absurdly accurately, to the point of fault and often pissing other folks of as I had no idea why they said something when it was absolutely false... This combined with a nearly faultless audio sense of memory (not eidetic) got my into frequent trouble with people getting mad at me not got arguing, but for always being right.

So I ask... Who exactly did they stick under the microscope here? I'm not bitching; I really want there to be more and better research here, but I'm skeptical of most that wraps up things in so neat a headline or category. What variations of spectrum? Did they compensate for more societal assumptions and myths than has been the history here?

The paper itself lists a highly limiting scope, with effectively a bias that would have eliminated all 3 of us from consideration for various reasons. Instead, they are polling data from effectively a group that in glance looks like a socially acceptable grouping, leaving out a huge block that have any metal illness diagnosis based on 2013 DSM.... A joke in itself here.

I appreciate that they are trying to look at an early development baseline to see what forms differently at crucial 1-4 year ages and then watching confirmed formation changes in later life. My concern is that ruling out what at a glance is a huge sampling purely on assumption that "mental illness" and a few of the other limits they imposed have boxed them into the old single flavor diagnosis again.
