"Aluminum, the theory postulated, becomes concentrated in the characteristic lesions (senile plaques and neurofibrillary tangles) that develop in the brain during the course of the disease. At first, medical scientists thought this theory was absurd. Aluminum, they believed, accumulated merely as a result of a destructive process caused by some other factor.posted by Civil_Disobedient at 7:48 PM on September 23, 2004
In recent years, however, the aluminum hypothesis has been gaining respect. For example, studies have discovered a direct association between the level of aluminum in municipal drinking water and the risk of Alzheimer's dementia. One study found aluminum in drinking water was related to only this specific type of dementia; another found that the probability of the association being due to chance was only 1 in 24, with a 46 percent increased risk for people drinking water with the highest aluminum levels.
The use of aluminum-containing antiperspirants--but not the use of antiperspirants and deodorants in general--has also been associated with a risk of Alzheimer's dementia, with a trend toward a higher risk corresponding with increasing frequency of use. This relationship does not extend to aluminum-containing antacids, which may simply be evidence that the aluminum in antacids is not absorbed--the process of absorption through the gut mucosa is quite different from absorption through the skin.
