You are absolutely correct. It can reach that point where most of the mercury is poisoning the brain, to where a person can just experience continual problems that don't seem able to be resolved.

But in order to chelate the brain, you have to make sure you're body area is detoxed, plus that there is no redistributed mercury floating around. Because you wind up worse for wear if you attempt to chelate the brain in either of those circumstances.

But other than that, yeah the brain and organs are the areas that end up poisoned and need to be reached eventually with something that can get right in like lipoic acid (used safely and low dose) and cilantro (though not enough is known about cilantro to be able to use it in such a way that is known to be safe).

Just what I've learned, and read, but I don't know if anybody has THE answer. Wish they did.
