After reading reports linking aluminum with Alzheimer’s disease, I got rid of our aluminum pans and stopped buying aluminum foil. Now I’m wondering whether I should avoid deodorants containing aluminum chlorohydrate. What is your opinion?There is little support for the theory that aluminum causes Alzheimer’s disease, the most common cause of dementia. The exact cause of this disease is unknown, although the risk of Alzheimer’s is higher when there is a family history of this disease.
Interest arose in the relationship between aluminum and Alzheimer’s disease when certain experimental animals exposed to high aluminum concentrations developed abnormal changes in the brain that seemed to resemble those of Alzheimer’s disease. However, careful study revealed that these changes were actually quite different. High levels of aluminum have been found in the brains of kidney dialysis patients with a rare, serious disorder called dialysis dementia.
Again, these abnormal changes are unlike those of Alzheimer’s disease. Workers exposed to high levels of aluminum in industrial environments have no increased incidence of Alzheimer’s disease. Furthermore, careful studies to date have not shown an increased aluminum concentration in the brains of Alzheimer’s disease patients. Since there is no convincing evidence linking aluminum toxicity with Alzheimer’s disease, you need not worry about exposure to aluminum in your deodorant or cooking utensils.
