The study said that the amount of GABA doesn't matter, it's how the brain uses it, so I'm guessing just supplementing with GABA wouldn't help.
DD does not have autism but she cannot filter out environmental stimuli because of ADHD. In order to somewhat function in school she has to wear headphones and blast pop/rock music to block out normal classroom sounds. Some of the other symptoms mentioned also sound like ADHD or executive dysfunction. So I wonder what they would find if they looked at ADHD patients rather than autism.
