Overly decreasing inflammation in fetal brains causes over connection of neurons and leads to autism / adhd / schizophrenia?

Acetaminophen is not an anti-inflammatory.

Where I live, tylenol is generally seen as less effective and less risky than aspirin or advil. I wonder how many pregnant mothers have taken it in a misguided attempt to reduce the risk of side effects.

Acetaminophen is often recommended for pregnant women because NSAIDs carry risks in pregnancy that have been known for far longer. Indeed, the researchers here indicate that they recommend judicious use, not "broad limitation" because failing to manage fevers during pregnancy also carries risk. So there is no good option, only an understanding that all the options carry drawbacks and that we should go into maternal healthcare with our eyes open.

Ibuprofen is the big "no no" for pregnant women past first trimester.

Meanwhile, this is like a 'press release centipede' of AI summary links.

Oh good, we haven’t been taking that by the kilo since 1955.

Earlier post from today of a different study about the effects of paracetamol/acetaminophen on foetal development:

Paracetamol disrupts early embryogenesis by cell cycle inhibition - https://news.ycombinator.com/item?id=45006296 - Aug 2025 (167 comments)

I don't think this is a dupe of the linked post? This is a meta-analysis of several studies, while that other link goes to a specific study that happened to release a few days later.

Yes, I recognized that after I posted the comment, then took the [dupe] tag off this one.

We still can't have this on the front page whilst (or soon after) the earlier one is active; this is what we call a "quasi-dupe". It's a different story/study but about the same underlying topic, so it's not really able to sustain a substantially new/different discussion.

The right thing to do is for someone to post a link to this study in the other thread, which has already been done: https://news.ycombinator.com/item?id=45007686.
