Abstract
Late onset Alzheimer's disease (Alz) affects 40 to 50% of older populations of prosperous nations. Advancing Alz eventually renders the aficted
helpless and without memory. Other elders have some reduction in cognition but sustain sufcient capabilities to not be helpless and retain
sufcient cognition to live well until their fatal diseases. Despite decades of sound research and as many as 200 clinical trials of putative treatments
to halt advancing Alz, all attempts failed to yield an effective medication. Epidemiological research has identied many correlates (risk-factors) of
developing Alz. It is posited that an accumulation of the consequences of the various risk-factors is sufcient to induce Alz. Possibly, different
combinations of risks can cause sufcient chaos of the brain's physiology to be the conditions starting and advancing Alz. For example, insufcient
circulating B-vitamins, manifest as hyperhomocysteinemia, and regularly taking of drugs with severe anticholinergic burdens could cause such
wide-spread effects to be a setting condition for developing Alz. Both potential setting conditions can be rectied hence could prevent the
development of Alz. Other combinations of risks might be causal and might be treatable, hence preventing Alz.
