My dad had this. He died of cancer 3 months ago. He meet the counting rules. For those who don't know what that is. Counting rules is a statiscal probablity for having "impaired mineral transportation" (I believe 97.5 chance). He had amalgams with gold crowns on top and many. (galvanism increases mercury into your body) Mineral transportation is something that happens in rare gentic conditions (downs etc) and mercury can easily cause this. Interesting thing is. Certain people are more suspectable to mineral transport problems at lower levels of mercury, but anyone at enough of a dose of mercury. (spill, amalgams, fish, anything) will get this.

Thanks
