Abstract / Excerpt:

“Mercury has long been known to be a potent neurotoxic substance, whether it is inhaled or consumed in the diet as a food contaminant.  Over the past 15 years, medical research laboratories have established that dental amalgam tooth fillings are a major contributor to mercury body burden.  In 1997, a team of research scientists demonstrated that mercury vapour inhalation by animals produced a molecular lesion in brain protein metabolism, which was similar to a lesion seen in 80% of Alzheimer diseased brains. Recently completed experiments by scientists at the University of Calgary’s Faculty of Medicine now reveal with direct visual evidence from brain neuron tissue cultures how mercury ions actually alter the cell membrane structure of developing neurons.”
