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.

A lot of people in the corresponding Reddit threads claim that NAC (N-Acetyl Cysteine) might help.

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?

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.

Meta comment - what a weird comment to downvote. I am expressing curiosity in good faith after reading the article, with a fairly logical follow up. What is the point of commenting in this community if it's primarily cynicism and negativity?

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.
