no shit sherlock
Parents have been saying this for years- the whole time I've been on the autism scene (over 8 years now). Research into type 1 diabetes includes rafts of papers on the role of casein and/or gluten in triggering the condition along with a leaky gut (a model which of course is almost unpublishable in the autism field if you want your career to stay intact).
Family history here stacked with type 1 diabetes and a bit of MS thrown in for good measure. I will watch with interest.....
