Scientists concluded this in the 1990s, and then had to produce yet another study to unequivocally state it again after every time someone claimed to have found the “cause”.

This is part of the reason it was re-named ASD in the first place; it describes a set of atypical neurological development symptoms, not an identifiable state of being. Kind of like “cancer” describes an atypical cellular reproductive state, not a pathogen attacking your cells. Both can be caused by many different factors or combination of factors.

Of course, with ASD, it doesn’t even mean there’s anything particularly wrong most of the time; just atypical, resulting in a person whose thoughts are weighted differently than historically typical, with less interpretation of social cues and a greater ability to focus.

But chief US stientists have discovered that it's all caused by Tylenol!

I thought we already knew, it's a spectrum

In other news: scientists reconfirmed the wheel to be round.

Great so now I’ve been downing Tylenol for no reason?

FUCK!

In other words, "Scientists Conclude Both Trump & RFK Jr. Are Utter A**holes For Believing Autism Is Caused By Tylenol, And You Should Be Voting For Democrats Instead"

It’s multiple conditions we group together naively based on surface level symptoms. Same for many disorders.

The type that comes with gender and sexual fluidity, bendyness, ADHD = rccx caused ASD.

Then that will have multiple subtypes based on mutation combination within the rccx module.

(The RCCX module would’ve been excluded from the genetic analysis the report this article is based on - due to its complexity).

Severe/non-verbal ASD is more likely completely unrelated and caused by dendritic abnormalities (reduced or excessive branching, immature spines, disrupted morphology, etc)
