“Is there a link between aluminium and Alzheimers” you should find an article dated March 12 2018 by Yuko Haru Phd, Director of Ageing and Alzheimer’s Prevention at the Alzheimer’s Drug Discovery Foundation. According to that article some studies find a link other studies find no link and at present it seems we don’t have a definite answer.
It appears that Dr. Hara is employing the “precautionary principle”; which is difficult to argue.
BTW: His footnotes list an extensive array of scientific studies on the subject.
“Is There a Link Between Aluminum and Alzheimer’s?”
~ Yuko Hara, PhD (March 12, 2018)
“... There is no consistent or compelling evidence to associate aluminum with Alzheimer's disease. Although a few studies have found associations between aluminum levels and Alzheimer's risk, many others found no such associations. Due to the inconclusive nature of the findings, it may be advisable to limit excessive exposure.”
Suspicion regarding a link between aluminum and AD first emerged in 1965, when scientists used an aluminum-containing chemical in their research
. Injection of this chemical, aluminum phosphate, seemed to trigger cognitive changes and also neurofibrillary tangle formation in animal studies. These tangles were determined to be similar but not identical to the tangles found in brains of people with AD.
In 1973, brain tissue collected from deceased persons, known to have AD, were found to have high aluminum levels. Although this evidence was circumstantial, it led researchers to ask whether aluminum exposure might cause, or even increase the progression, of AD changes in the brain.
When large scale studies attempted to link aluminum exposure with AD, results were mixed. Animal studies have not supported the link between aluminum exposure and typical AD pathology, and that inconsistent results were reported in studies of works with high occupational aluminum exposure, finding both positive and negative results.
One of the most convincing of these studies, a careful investigation of miners from northern Ontario
exposed to aluminum, given as a protection against silicotic lung disease (disease caused by breathing in tiny bits of silica over many years), then examined thoroughly for toxic effects, found no statistically significant neurological or cognitive differences between exposed and unexposed miners.
Despite the inconsistent findings that have led many researchers to abandon the aluminum hypothesis, a few researchers remain convinced that aluminum increases AD risk. It would be fair to say, however, that this does not represent current
mainstream thinking about AD. If aluminum is a risk factor, it appears to be one of less importance than many others.
Nonetheless, "prudent caution over reckless abandon" can't hurt.
Does storing (or boiling/cooking) water
in Aluminum rise to the level of "excessive exposure"
It might be worth noting, that there are other good reasons to avoid aluminum water tanks
