There have been a lot of studies about the link between aluminum and Alzheimer's.  However, many scientists say the evidence is not enough to blame the metal.  This time, however, a new research confirms aluminum does play a role in cognitive decline.

There Is A Strong Link Between Aluminum Exposure And Alzheimer's

A research conducted by Chris Exley, a professor from Keele University, reveals that there is a strong link between human exposure to aluminum and the incidence of Alzheimer's disease for at least half a century. 

Professor Exley has been studying aluminum for 30 years and published at least 150 scientific papers on this subject.   According to Exley, it is already known that aluminium content of brain tissue in late-onset or sporadic Alzheimer's disease is significantly higher than is found in age-matched controls.

Therefore, people who develop Alzheimer's in their late sixties also accumulate more aluminum in their brain compared to people at the same age who don't have the disease.  What is notable is even higher levels of aluminum have been found in people who have had an early-onset form of sporadic Alzheimer's disease.  These people experienced an unusually high exposure to the metal through the environment or through their workplace.

Aluminum Is Poisonous Or Destructive To Nerve Tissue

Aluminum is known as a neurotoxin or toxins that are poisonous or destructive to nerve tissue.  According to Exley, "this new research may suggest that these genetic predispositions to early onset Alzheimer's disease are linked in some way to the accumulation of aluminium (through 'normal' everyday human exposure) in brain tissue.

The researcher also added that ageing remains to be the main risk factor for Alzheimer's and that aluminum accumulates in the human brain as it ages.  "We should take all possible precautions to reduce the accumulation of aluminium in our brain tissue through our everyday activities and we should start to do this as early in our lives as possible," Exley concluded.
