No aluminium, no Alzheimer’s disease

The Emperor is Naked: No aluminium, no Alzheimer’s disease. This is the, perhaps unexpected, conclusion of a new open access paper published in Journal of Alzheimer’s Disease Reports. Putting the headline in context what is actually being suggested is that brain content of aluminium is a catalyst for Alzheimer’s disease. In the absence of pathologically significant deposits of aluminium in brain tissue there would not be any (acute) Alzheimer’s disease within a normal lifespan of say 100 years. Support for this conclusion has been building over the last decade or so and has now been put on an unequivocally firm footing by recent research demonstrating the exceedingly high content of aluminium in brain tissue in individuals who died with a diagnosis of familial Alzheimer’s disease.

Individuals with familial Alzheimer’s disease have specific genetic predispositions to Alzheimer’s developing earlier in life, perhaps as early as the fourth or fifth decade of life. All of these genetic predispositions are associated with how the body metabolises the amyloid precursor protein (APP) and yet there is no unequivocal explanation of how APP and its metabolic products, such as amyloid β cause Alzheimer’s disease. The contention in the new research is that these genetic mutations in the metabolism and processing of APP concomitantly act as predispositions to the retention of aluminium in brain tissue. Increased absorption of aluminium across the gut, as is seen in late-onset Alzheimer’s disease and in Down’s syndrome, could contribute to increased retention of aluminium in brain tissue. However, while we do not know the mechanism behind this increased retention what we do know is that when brain aluminium content is increased, and not because of specific genetic mutations but due to environmental or occupational exposure to aluminium, then an earlier form of late-onset or sporadic Alzheimer’s disease will occur.

There are clearly many potential contributory factors in the aetiology of Alzheimer’s disease but what is now being suggested is that without concomitant pathologically-significant deposits of aluminium there would not be any Alzheimer’s disease.

It is intriguing that the first reported case of Alzheimer’s disease, which occurred less than 20 years following the advent of the aluminium age, was in a woman in her fifties and we now know that she was also the first documented case of familial Alzheimer’s disease. We would expect her brain to be characterised by pathologically-significant deposits of aluminium!

I have been saying this for years. It is so blatantly obvious that the phosphoric acid in most soft drinks combines with the aluminum in the cans and provides thus a perfect vehicle straight to the brain where it forms the plaques associated with Alzheimer’s and other neurodegenerative illnesses. The massive influence of and lobbying by the aluminum industries have put this to rest decades ago, sweeping it under a rug with so much already swept under it by corporations that the normal instincts for survival and self preservation are forgotten and ignored
