I will be adding to this post.
"Aluminum - is there a link to Alzheimer's disease?", 2016, color and bolding added by me
http://www.alzheimer.ca/en/About-dementia/Alzheimer-s-disease/Risk-factors/Aluminum
"Some studies show increased levels of aluminum in the brains of people with Alzheimer's disease ... others do not. ... Research has not found an increased incidence of Alzheimer's disease in people with occupational exposure to aluminum. ...Tea is one of the few plants whose leaves accumulate large amounts of aluminum that can seep into the brewed beverage. ... no evidence that Alzheimer's disease is more prevalent in cultures that typically drink large amounts of tea. ... earlier animal studies focused on one animal that is particularly susceptible to aluminum poisoning, thus leading to incorrect conclusions about the general effects of aluminum on the body ... At this point, there is no convincing evidence that aluminum increases a person's risk of developing Alzheimer's disease."
"Does aluminum in pans and antiperspirants lead to Alzheimer’s disease?", 2013

“If aluminum plays any role, it’s very small,” ... “And there are many other, much more important risk factors to study.”... You can try to limit your aluminum consumption by choosing aluminum-free products, Perl says, “but we don’t really understand enough about [aluminum’s possible association with Alzheimer’s disease] to make good recommendations.” For what it’s worth, Perl and Borenstein haven’t replaced their cookware, changed their antiperspirants or given up using aluminum foil. Savory hasn’t, either"
"Antiperspirants and Breast Cancer Risk", 2014

"no clear link has been made between antiperspirants containing aluminum and breast cancer"
This 2014 study is overhyped a number of places in media.

"While it is impossible to know if high levels of brain aluminium instigated disease in either of these cases it is highly likely"
"Highly likely" is not definitive, or proven. My mother and grandmother used aluminum cookware most of their lives. Neither developed Alzheimer's disease. Occupational exposure is significantly different to using cookware, aluminum foil and antiperspirants. More research is the key. Not scams!
