    > We want to start creating a developmental story and start understanding whether the things that we’re seeing are the root of autism or a neurological consequence of having had autism your whole life

      Yeah, how many studies are done a year? Random chance is the #1 explanation with that small of a sample size. It doesn't take a degree in stats say that the next thing that needs to be done is to replicate the study a few times before making any claims or searching for any publicity. This subject is so emotional for the families involved that publicizing without more confirmation is a bit irresponsible especially if it is easy to do follow-up studies.

        Follow-up studies cost money, and you don't get any of that if you don't publish.

        It's a university press release. Hyperbole in practice.

        Wish I could read the paper.

    The metabotropic glutamate receptor subtype 5 (mGlu5) is involved in the central mechanism of action of paracetamol (acetaminophen), where the bioactive metabolite AM404 activates the TRPV1 channel–mGlu5 receptor–PLC–DAGL–CB1 receptor signaling cascade in the periaqueductal grey, contributing to its analgesic effect.

      Didn’t whole internet get angry for Trump’s administration publishing a warning that Tylenol during pregnancy may cause autosim?
      • ijustwork 32 minutes ago
        Of course they did. Plenty of propaganda mouthpieces for big pharma like PBS rushed to publish articles explaing how Trump was wrong and all the studies were being misinterpreted despite J&J jettisoning Tylenol from its portfolio in 2023.

          Bit rich coming from a sockpuppet account created 57 minutes ago...

          - exclusively commenting on this thread

          - uncritically addressing it from a very specific angle

          - mentioning specific things that sound related while not actually connecting them to the overall story with the same rigor

          ...isn't it?

          Anything claimed without evidence can be dismissed without evidence.

        Can you explain the logical leap you're making here? Unless this is RFK Jr we're talking to, you're comparing two wildly different contexts.

          What is so difficult for you to understand?

      This could potentially explain why parents believe vaccines cause autism if the child was given excessive Tylenol for a bad vaccine reaction.
      • diydsp 30 minutes ago
        The vaccine autism hoax is traced back to one specific discredired researcher:

          You are wrong and discounting the observed effects of many parents. Please dont use Time Magazine as a medical reference.

          EDIT: As expected I've already been rate limited. The scientific method starts with making observations. What do you suggest? Bribing the CDC to delete all the data from studies supporting a link? Having big pharma pay for propaganda studies to muddy the waters and then blasting them ad-nauseum at anyone who goes against your installed narrative? Because that is exactly what happened if you look beyond the headlines.

    Very interesting - wonder when this will be cost effective for testing!
  • NewUser76312 2 hours ago
    Interesting indeed. Does such a finding suggest any worthwhile easy-to-try 'treatments' that may help alleviate symptoms?

    I don't know much about the biochemistry here, I assume this is not something like GABA that can be directly supplemented. But maybe there are precursor nutritional and supplemental substances that can help these people upregulate how much of the glutamate molecule in question the body can produce.

      Unless you can get the blastocyst and fetus to take supplements, any treatment would be attempting to undo the effects that have already taken place.

      For now, your best options are ESDM, occupational therapy, modified CBT, ABA, or neurofeedback, depending on your circumstances and presentation. Except for neurofeedback, these are behavioral approaches, so the architectural and neural activity variations aren't directly addressed.

      There isn't enough information to start doing that. Consider: UV exposure results in sunburn, cellular damage, and increased skin pigmentation. We have medication that reduces skin pigmentation. Should we give it to people who experience chronic sunburn?

      The third paragraph:

      > Now, a new study in The American Journal of Psychiatry has found that brains of autistic people have fewer of a specific kind of receptor for glutamate, the most common excitatory neurotransmitter in the brain. The reduced availability of these receptors may be associated with various characteristics linked to autism.

      Reduce receptors. This might suggest a _developmental_ or genetic link. Think of this more like "height" or a particular "facial feature" of a person.

    can we use this to detect all the tiktok normies who are now claiming they have autism to be spedcal? that is the question.

      It would also be interesting if there's no link to be found.
