Did I say you can cure autism with B12 shots? I don't think so. I said my son was diagnosed as autistic, showed marked improvement within 24 hours of MB12/L5MTHF injections, and after the fact we came to discover homozygous 677T mutation, for which MB12/L5MTHF would have been the primary course of treatment had we not already embarked upon that path.

My post is more about how something with a very specific root cause, e.g. methylation problems, was diagnosing as autism (across multiple doctors, naturopaths, pediatricians, etc), and how it may be the case that some subset of autistic kids could be in a similar boat. From that study itself "However, detailed data analysis suggests that methyl B12 may alleviate symptoms of autism in a subgroup of children, possibly by reducing oxidative stress."

What I'm a proponent of is genetic screening (a simple blood draw + lab work) for an autistic child to look for 677T/1298C mutation. That's a known problem with a known treatment and I don't think there's anything irresponsible in advocating for that.

Autism is such a wide-net term that I would have a hard time inferring any meaning from a study that simply categorizes the subject(s) in a binary autistic/not autistic manner. e.g. which ones were vax injured, which ones have gut issues, heavy metals, yeast overgrowth, genetic conditions, etc. Many children imaginably require a multi-pronged approach so to try just one particular approach against an unqualified set of subjects seems bound to disappoint.
