This sounds like an oversimplified therapy. I'm sure this treatment would have an effect on anyone. It's simply increasing oxygen and blood flow.

As a person with autism, I think there is much more merit in the idea of a GABA imbalance in the brain. There are studies showing a deficit of GABA in autistic people. I think that's why certain drugs like alcohol, in moderation, can make autistic people more normal instead of drunk.
