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.

God, why are so many people commenting out of their depth today.

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

No. This isn't how it works at all. Receptor counts are extremely plastic, able to change within a weeks and in some cases hours. This is how you get drug tolerance.

		Sure, but they're also 15% lower in people with autism, and shown with a 60-90% heritability. Supplimentation would not rewrite SHANK3. You can go to the dentist and get your teeth aligned, but there's a very good chance your children have similar issues.
