DT: Possibly true about chlorinated VOCs being more likely to kill them, but then, exposure during fetal development didn't kill your sister right away. It did, however, potentially make her sensitive to later exposures.
We are considering this possibility, but they do kill many infants before and after birth. This has been documented in Vietnam, where CFCs as a WMD have been most widely used.

The variations in diagnosis will be random, and will appear as signal noise on the map. That's easy to filter out. In vietnam, infant cancer maps show a very clear adherence to the borders of particular watersheds where Agent Orange was used. It demonstrates a clear relation to the water contamination. Similarly, the lung cancer maps mimic the smoking maps. Those maps both have signal noise, because diagnosis rates differ based on the quality of local hospitals, etc.
Fluoride is used to create CFCs. By itself, it's probably relatively harmless to humans, but not completely, overall, I'm not worried. I think it's either dumb or evil to use chemical weapons in your own drinking water, but CFCs already formed are much more dangerous I agree.

I do wonder at the mechanisms of the autism disorder.
Quote:Here's an interesting thought: Because of the "blood-brain barrier", the hormones and peptides on one side of the barrier don't "see" what same the hormones and peptides are doing. For example, the immune system is NOT supposed to be active in the brain. If you have white blood cells in the brain, you've got a big problem!
If it's a matter of the brain tissue being affected somewhere, the brain is a complicated organ, and there are a number of things that could contribute to the condition, and autism does have a broad range of symptoms that aren't always easy to narrow down to a specific cause in all cases. Your vip proteins, for example, perhaps indicate an issue with correctly absorbing nutrients, which might then suggest nutrient starvation in the brain.
So rather than having two entirely novel signaling systems, the body uses the same hormones and peptides in different ways, with different receptors and different effects depending in which side of the bbb it's on. Calcinuerin, for example, promotes synaptic growth in the brain but is part of the immune response in the body. Phosphatidyl serine is a neurotransmitter in the brain, but in the body it's a "flag" for the macrophages to pick up a piece of garbage. VIP is a smooth muscle relaxer in th gut, but in the brain it appears to play a big role in circadian rhythm. Anyway, I think you get the point.

Huh! Okay, yeah, that's also potential mechanism.
I read a really interesting article once about how deregulation of the circadian rhythm can play a big role in dementia and the comatose. There was a guy, he was going around injecting electrodes in the skulls of people in persistent vegetative states in the area that governing this, as well as areas governing the process of waking up from sleep.
Some of them woke up. What's more! Some of them, despite their initial accident and subsequent coma having resulted in extreme losses of brain tissue to the point where their doctors considered their brains partially slurrified, actually woke up with their memories intact, personalities intact, and able to communicate!

That's interesting Byte.
I respect DT's knowledge of chemicals and what they can do, he knows a lot about the subject.

Studies from various countries are indicating that autism rates among children might be greater than current estimates. A study from South Korea is being released which contends that it is more common than most think. The study found that more children really had autism than were diagnosed with autism among the general population. The study implies that several children are not diagnosed, though they have an autism disorder.

I looked up your cite. http://www.news24.com/SciTech/News/Autism-may-be-under-diagnosed-study
-20110509
The study was funded by Autism Speaks, and when I look at the wikipedia entry on the organization, it's an advocacy group with a powerful lobby that raises grant money for research into the condition.
The article itself calls out the probability of changes in diagnosis style being a contributor to increasing rates of autism diagnosis. It also suggested that the study may pre-select with parents who have concerns about their children's behaviour, which would skew diagnosis higher.
You may want to look at the claim of underdiagnosis with some caution, particularly when using more recent diagnostic measures. There's an element of both schools and pharmaceutical industry that get some benefit from false positives, which the broadened criteria can provide.

Thanks, and I respect Sig's, and also PR's. Things that cross the blood brain barrier usually do so in an incomplete form. No question about it that CFCs do, but the lighter weight CFCs, the ones that are found more in vapors, tend to cross the BBB easier. I know for a fact that methylene chloride (DCM) and tetrachloroethylene do. I think tetrachloroethylene may break down into DCM in a way that I'm less sure about tri- TCE, though I'd put it up there in the same category of toxicity.
ETA: Correction, CFCs used in WWI, reaction causes DNA mutation, so yeah, lots of those exposed would have gotten cancer and died months later, but no one was paying attention to that effect.
