Since Alzheimer’s disease barely existed a century ago the growing rates of the disease prevalent today now meets the definition of a global epidemic. Alzheimer’s is another severe neurological disorder similar to autism, except occurring in adults. Current research strongly suggests that mercury exposure plays a role in the development of the disease. Scientists have shown that trace amounts of mercury can cause the type of damage to nerves that is characteristic of the damage found in Alzheimer’s disease.
Mercury has been found to induce or increase the production of all of the hallmark signs of Alzheimer’s disease including neurofibrillary tangles, tau proteins, beta amyloid and senile plaques. Dr. Boyd Haley, previous Chairman of the Chemistry Department at the University of Kentucky demonstrated Alzheimer’s disease-like brain damage to rats from inhaled mercury vapor. Dr. Haley, commenting on the importance of this new documentation said, “Seven of the characteristic markers that we look for to distinguish Alzheimer’s disease can be produced in normal brain tissues, or cultures of neurons, by the addition of extremely low levels of mercury.
While not the only possible cause of Alzheimer’s disease, the evidence for mercury at the very least indicates a need for precautions against mercury exposure. World Mercury Project recommends individuals of all ages should avoid exposure to mercury for all sources; seafood known to contain high levels of mercury, mercury amalgam dental fillings, and vaccines which are preserved with the mercury based preservative thimerosal.
Are Mercury and Alzheimer’s Disease Linked?
In his Commentary , Dr. Chakraborty stresses the potential hazards of low-level long-term exposure to mercury and the increase of prevalence of Alzheimer’s disease in the general population of India, a view we wholeheartedly endorse. We applaud the tenor of the piece (Chakraborty, 2017) and we have some additional points to make as well.
How Mercury Causes Brain Neuron Damage
Medical laboratories have established that dental amalgam tooth fillings are a major contributor to mercury body burden. This short presentation on University of Calgary’s Faculty of Medicine’s website reveals how mercury ions actually alter cell membrane structure and how mercury in fillings can destroy brain neurons as seen with people who have Alzheimer’s Disease.
Association between dental amalgam fillings and Alzheimer’s disease: a population-based cross-sectional study in Taiwan
Dental amalgam, a material for filling prepared cavities after removing caries, consists of about 50 % mercury . Mercury vapor has been proven to be toxic to the central nervous system. In 2008, the European Commission asserted that there is no evidence showing negative effects on the human central nervous system when applying amalgam fillings as reported in previous studies.
Does Inorganic Mercury Play a Role in Alzheimer’s Disease? A Systematic Review and an Integrated Molecular Mechanism
Abstract. Mercury is one of the most toxic substances known to humans. It has been introduced into the human environment and has also been widely used in medicine. Since circumstantial evidence exists that the pathology of Alzheimer’s disease (AD) might be in part caused or exacerbated by inorganic mercury, we conducted a systematic review using a comprehensive search strategy.
