Thanks for all the responses. I have read many of these articles already but did join the forum on Yahoo. However my question was not actually asking if mercury CAUSED high cholesterol, I was actually trying to figure out what a common denomenator could be in regard to why only SOME children are affected by Thimerosal and others are not. All 4 of our children have multiple disibilities. Autism, ADHD, PICA, Bi-polar Disorder, Learning disibilities, epelipsy, and the list goes on. The children were adopted and Brandon whom is the youngest we got at 4 1/2 weeks old. He was a healthy normal child untill after his vaccinations. At around 18 months he began to regress. The children are less than a year apart in age and all had shots between 1997 and 2000. One thing they all have in common is high cholesterol. Cholesterol can not travel through the bloodstream by itself, or that is my understanding. It needs some help as it is a sticky waxy substance. It needs to be lubricated. Would mercury not be a lubricant? If the mercury traveled with cholesteral it could attach itself to the brain and other organs using the cholesterol as a binder. Does this sound too far fetched?
