Mercury harms brain tubulin, the most important protein in the brain, and is severely toxic to neurons. Professor Boyd Haley warns that our brains have no protective mechansim against the damage done by the mercury vapor given off from dental amalgams.
Even low levels of mercury exposure can damage human nerve cells, Haley warns, and cause all of the signs of Alzheimer's disease, a leading cause of disability and death. Far more than any other toxin, mercury produces all the hallmarks of Alzheimer's disease: greatly decreased glutathione levels, neurofibrillary tangles, abnormally aggregated tubulin, increased hyper-phosphorylation of protein-Tau, and increased production of beta-amyloid protein, which makes up amyloid plaques.
Mercury has been linked to Alzheimer's more than any other toxin, including Aluminum, Haley warns, and the rate of Alzheimer's disease is growing and is projected to increase much more in coming decades. Haley, a world's expert on human toxicity issues, urges that dental amalgams, which are half mercury, be banned. Doctors have missed the mercury diagnosis for a long time because they only did a straight blood test and not a chelation challenge test.
