Chris Exley's work on the link between aluminium and Alzheimer's is at last becoming mainstream, with this latest paper citing cases that I have been able to secure for his research despite the obstruction of the Establishment (his references nos 13 and 14). Chris works closely with Lucija Tomljenovic, at Vancouver Uni, Canada, since both are researching the harmful effects of Al adjuvants in vaccines. Their linked work comes together in Christina England's and Lucija Tomljenovic's recent book "Vaccination Policy and the UK Government:The untold Truth" .
Both Chris and Lucija are hugely resepected international researchers. So we're dealing with hard-nosed and real expert scientists here, working within a very wide international collaboration of top experts, and not just a small bunch of semi-literate dental health 'researchers' irrationally obsessed with fluoridation.
So here's what Lucija wrote six years ago in  'Aluminum and Alzheimer’s Disease: After a Century of Controversy, Is there a Plausible Link?'. (Journal of Alzheimer’s Disease 23 (2011) 567–598. DOI 10.3233/JAD-2010-101494  -  Chris Exley was one of the Editors of this Edition): Remember, this warning has been out in the public domain for six years, and even then was by no means the earliest alert to what, eventually, was to become better more widely but belatedly understood.

From these observations it is evident that in the presence of fluoride, only trace amounts of Al are needed to produce substantial neuronal injury. Both fluoride and Al when complexed in AlF–x appear to be more easily absorbed from the gastrointestinal (GI) tract compared to their ionic forms [39, 82, 83]. In spite of these observations, water fluoridation persists in USA, Canada, Australia, and New Zealand while most of Europe has abandoned this practice [77, 84]. Of note, contrary to World Health Organization (WHO) predictions, the incidence of dental caries has decreased significantly after the suspension of water fluoridation in Japan and many European countries [84]. In fluoride-treated water, fluoroaluminates are the prevalent species [39]. The enhanced transport of fluoroaluminates across the GI tract and the BBB,[Blood-brain barrier] in context to their highly neurotoxic potential, raises significant concerns about the prevalence of these compounds in drinking water of various countries (my emphasis)

Unlike much of the research relied on by opponents of fluoridation, this is not just woolly speculation over apparent correlations. This is hard toxicological data confirming an actual causal pathway and a direct response to exposure to an environmental neurotoxin, aluminium.  And astonishingly, the conditions under which this dangerous interaction between aluminium and fluoride occurs are absolutely characteristic of those that occur in supposedly 'optimally fluoridated water'. 
Well-meaning public health officials attempt to provide the public with water supplies that are clear and attractive, through the use of aluminium-based flocculants at water treatment works. Then they order the water companies to add another neurotoxic chemical - fluorosilicic acid -  that they tell us, against all the real 'best available' evidence, will help prevent a disease of our children - tooth decay.This they proclaim even though tooth decay is far less prevalent now than it was in our own childhoods. .
So I wonder if, like me, any of your readers find it a little ironic that we have now come to rely on putting two known neurotoxic elements - aluminium and fluorine (as fluoride) - into our hallowed drinking water, and in exactly the right proportions to ensure the formation of an even more lethal form of toxin. A toxin, moreover, that has now been shown to be responsible for the greatest threat to public health that we have ever faced in a long history of well-meaning public health bungling and stupidity?
With friends such as these, who could seriously fear any enemies?
