One of my personal observations is that patients diagnosed with Alzheimer Disease seem to have remarkable immunity to other diseases such as cancer and heart disease. People with Alzheimer Disease seem to live much longer than the average lifespan, even though the Alzheimer Disease FAQ page states: "People usually die of secondary infection, such as pneumonia."
Has there been any statistical analyses on the lifespan and the cause of death on the people who had Alzheimer Disease?
Since it is known that the brain with Alzheimer Disease has higher concentration of aluminum in the brain tissue, certain aluminum compounds in plaques (extracellular deposits of a protein fragment called beta-amyloid) and tangles (fibrous clumps of a protein inside nerve cells, or tau phosphorylation) may in fact enhance the immunity against other diseases.
I would like to know from the experts if there is any research opportunity to study this Alzheimer Disease Paradox further.
