This seems to bolster the theory that autism is modulated by the gut-brain axis. Being given antibiotics at such an early age will probably severely dysregulation gut microbiota. And GABA actually does cross the BBB but in small amounts. Perhaps at such an early age, dysregulation in GABA produced in the gut has significant effects on brain health - over stimulation, learning memory issues, etc.

Reading the article, it turns out the one twin who is "more autistic" had a hole in his heart that surgery had to correct. So I suspect the actual issue here is something simpler like a difference in brain development because of the difference in the amount of blood flow.

...or just being in the hospital environment for a month. The older theory they mentioned here:

> "The earliest twin studies really helped to debunk this theory that autism was caused by parenting," Morris says. Under this theory, moms took the brunt of the blame, supposedly for being "cold and distant and detached from their child."

...might not be entirely wrong. They've since shown genetics is a factor, and I'll ignore the institutionalized misogyny part, but being in a hospital for a month probably did mean having much less parent/care-giver interaction/touch during a critical period, and who knows how much of an effect that could have.

This has been studied a lot in child welfare and is not currently believed, afaik. The diagnosis of reactive attachment disorder is acknowledged to have many overlapping symptoms with autism, but expressly differentiated as a condition.

Before the heredity nature of autism was accepted, this was the school of thought (“refrigerator mothers”). But in truth, it’s neurodivergent parents having neurodivergent children, and society punishing the parents (namely mothers) for their inability at providing the “expected” nurturing conditions.

Tied back, atypical behavior.may create neurodivergent conditions, but one would expect children of aurististics to seek less overall care which doesnt support the hypitheses that antibiotics are causing aitism as this thrwad started

My theory is that this causation is flipped. Something about whatever the precursor to autism is causes the body to experience more physical failures or malformed structures.

Something like whatever mechanisms decode structure from the genome are faulty and produce slightly wrong structures throughout the brain and body.

Anecdotally, I see a higher rate of general illness and physical birth defects in autistic people.

Another way to think of this is that 'autism' is a broad series of disorders where individuals do not follow the social-relational cues we expect. There are many ways to violate unspoken social expectations, so there should be many ways to be autistic.

In this setting, it's not unreasonable that any genetic syndrome would be more associated with autism; indeed, it's more interesting to find lesions that have a lower proportion of autistic carriers compared to the general population.

Re:Identical twins both grew up with autism, but took differ... by crisply5706 on Sunday April 14, 2024 @08:49PM (#40035928)
Yeah, I suspect it's quite likely that autism is correlated with/caused by genetic disorders in general, rather than being its own thing that just happens to be comorbid with a suspicious number of other disorders.

There's too many correlations that aren't common enough, I really think we've got the causality backwards. But then again I don't know anything

There’s a correlation between autism and mitochondrial dysfunction:

https://www.nature.com/articles/mp2010136

> Most ASD/MD cases (79%) were not associated with genetic abnormalities, raising the possibility of secondary mitochondrial dysfunction. Treatment studies for ASD/MD were limited, although improvements were noted in some studies with carnitine, co-enzyme Q10 and B-vitamins. Many studies suffered from limitations, including small sample sizes, referral or publication biases, and variability in protocols for selecting children for MD workup, collecting mitochondrial biomarkers and defining MD. Overall, this evidence supports the notion that mitochondrial dysfunction is associated with ASD. Additional studies are needed to further define the role of mitochondrial dysfunction in ASD.

FWIW, I have identical twin sons who probably have mild autism. One had an umbilical hernia like the lad in the story. They both had a couple of other small developmental anomalies. But they were both slightly premature (like most twins) and shared a womb. So what's the driver here? One of the above, or possibly the hormones which they were (incorrectly) given to promote lung function? There's a lot to unpick.

A friend underwent operation of his aorta. Post-surgery inflammation is an absolutely common complication and they dumped a lot of antibiotics into him precisely to reduce the risk. (If I understand correctly, it wouldn't be probably fatal, but very, very unpleasant.)

Whenever I had (minor) surgery in France, I was given antibiotics "as a shield". I obviously do not know if this helped or not.

Now, French doctors were always very quick to prescribe antibiotics (as a kid I had plenty of them) and it took quite a lot of effort to change their(and parent's) mind. My children got much less, though they were almost never checked for virus vs bacterial infection.

I know I'll be downvoted, but I'll say it anyway.

What is never discussed, and isn't considered in this article, are certain types of other medical interventions - vaccination. Looking at certain (hard to find) videos by the deceased Dr Andrew Moulden, one is given some support for the theory that vaccines cause ischemia (small strokes). For the very young, the brain does not 're-route' and developmental milestones are simply missed, whereas in adults it's possible to relearn skills. Autism can be an impact, and one can also see physical impacts in the face, such as wonky smiles, wonky eyes, as different strokes cause various issues.

Re:Identical twins both grew up with autism, but took differ... by lazyasciiart on Sunday April 14, 2024 @03:25AM (#40029334)
Amazingly enough, this Andrew Moulden is a completely unrelated person to Andrew Wakefield, with his own much more sincere but correspondingly more crackpot theory for why vaccines cause autism. I think it can be well summarized as “germ theory is wrong; germs (viruses and bacteria) don’t cause diseases, foreign particles entering the body causes them”. This claim is clearly and fundamentally wrong, just like the claim about neuroplasticity that you quote. There is no value in his work.

Moulden was a snake-oil peddling quack with a degree in psychology who was never licensed to practice medicine. He peddled something called "BrainGuard" that purported to diagnose autism by looking at a picture or short video of a child or even a baby.

It's very frequently discussed.

The downvotes you're expecting are because this meme can be traced to a fraudulent claim in 1998: https://en.wikipedia.org/wiki/Lancet_MMR_autism_fraud

I declined the MMR vaccine at school because I was at school when that story came out, and at that point he and his claim were taken somewhat seriously.

(I did get the vaccine eventually).

> For the very young, the brain does not 're-route' and developmental milestones are simply missed, whereas in adults it's possible to relearn skills

That's the exact opposite of how it works. E.g. language acquisition in adulthood is much harder.

It’s extremely common for young kids to receive antibiotics. In some countries, antibiotics are over the counter and many parents will give their kids antibiotics for nearly any infection. Antibiotic misuse is rampant in some countries where they aren’t gated behind prescriptions.

Any such link with autism would therefore be an extremely rare side effect. The rate of antibiotic use in children is far higher than the rate of autism.

I don’t think this case supports the antibiotic theory by itself at all. I think it’s confirmation bias because antibiotics are one of the current trending theories among mainstream discussion.

Re:Identical twins both grew up with autism, but took differ... by Aurornis on Sunday April 14, 2024 @01:48PM (#40032886)
No it is not, but ignoring the part about the severe infection require extended hospitalization and trying to reduce it all to “antibiotics” is extremely disingenuous.

Given that antibiotics are common but extreme infections and extended hospitalizations are not, why would anyone focus on the antibiotics as the root cause?

Not all antibiotics are created equal nor do they affect gut bacteria the same. There isn’t a singular scale for antibiotic power. Often, antibiotics are given via vein because they aren’t absorbed from the gastrointestinal tract, for example. This doesn’t tell us anything about the magnitude of impact on gut bacteria relative to an antibiotic that actually starts its journey in your gut.

This is a complicated case. Reducing the entire complicated episode to “it was the antibiotics” is extremely reductionist.

Not really.

"The infection was from drug-resistant staph bacteria. So John went back to the hospital and spent a month on powerful antibiotics pumped directly into a vein near his heart."

There are so many confounding factors here. Could be no connection to the episode whatever. Could be that the infection that required the antibiotics contributed to the autism. Could be the antibiotics contributed directly. Could be the overall trauma of the surgery, treatment and recovery.

Seems like the gut thing is the least likely culprit and requires quite a lot of creativity to even consider it.
