Only read the abstract, but this paper seems to rather link the onset of autism to the gut microbiome. Very interesting though! Scanning the brain or your DNA would still work I guess. If a person has autism, they could theoretically show neurological differences. But maybe the variance of brains is just to large to ever be able to tell…
