I odn't think anyone for a minuteis suggesting that bowel disorderscause autism.
I saw this on the news last week, and haven't had a chance to try to chase it up. It certainly looks intriguing.
From what I have gathered (and am back to using my phone, so a lot of links won't open for me) they looked at urinary profiles, and didn't select on the basis of gut dysfunction.
The conclusions seem to be that autistic individuals process foods in different ways, possibly due to different gut bacteria.
As a result, they are left with by-products which are dectectable in urine.
I know Sunderland worked along these lines too - testign for waste by-products due to incomplete breakdowns of certain foods. Sunderland, of course concentratedon glutenand casein (proteins) - the new study also focusses on proteins.
What was interesting about the findings is that there were three distinct groups:
NT children
NT siblings of autisitc children
ASD children
all with distinct urinary profiles.
THat is quite interesting.
I know Sunderland at one point said that up to 85% of ASD people might have difficulities breaking down casein and gluten - NOT that all of them would have bowel issues. I think it worked on a sliding scale.
What I do know is that dd1 has a typical LEaky Gut profile, according to Sunderland protocol (off the scale for gluten by-products). She did have bowel issues, which improved amssively after withdrawing gluten.
My step-son was also tested (NT) - his profile showed up as "not normal" - he is very clearly not NT (we were trying to persuade my step daughter to test, which is why he was tested)
Dh also gt tested (out of curiosity, since dss tested as not normal) and also came up with a "not normal" urine profile. whilst both of them did not show typical leaky gut profiles, they did not fit the normal range either.
All ttally anecdotal, of course.
But interesting nonetheless.
I don't think anyone is suggesting that this test would be the be all and end all. But if t is possible to pick up a percentage of ASD children so easily - well, I'm all for it.
