Aluminum toxicity is one of the most commonly cited factors in the development of dementia and Alzheimers disease.  Cookware and utensils has been a major of source of exposure.  Increased awareness has brought a reduction in the domestic use of these implements in more recent years, but comes too late for the current elderly generation amongst whom dementia has become epidemic.  Even so, cooking techniques which bring aluminum foil into direct contact with foods are still common and the use of aluminum cookware is still widespread in institutional cooking and restaurants, as well as the developing world for reasons of affordability and convenience.

Pharmaceutical medication is another often overlooked route by which aluminum is introduced into the body.  While the presence of mercury has gained much more notoriety, aluminum is also used as a preservative in vaccinations and other drugs.

It is no wonder then that in the homeopathic treatment of dementia, a remedy derived from aluminum - or more specifically aluminum oxide is one of the most common prescriptions.
