Alzheimer’s disease: Causes, Risk, Factors, and Stages
In today’s world Alzheimer’s disease is causing a big impact in the older population. Being the principal cause of dementia, Alzheimer cuts the life of people who suffer from this disease. Because it causes problems with ones memory, thinking, and behavior, it affects people's daily life and social abilities.

This number is expected to triple by the year 2050 as the population ages.” (Mayo clinic, 2007)
Causes and Risk Factors
Even though about four million people suffer from Alzheimer’s today, there is not a clear explanation of what causes Alzheimer’s. However, what the researchers know is that it involves the failure of nerve cells; damaging and killing brain cells.
In autopsies of people who had died from Alzheimer’s Drs. have found a big quantity of plaques and tangles; plaques build up between nerve cells and tangles inside nerve cells. “Plaques are deposits of a protein fragment called beta-amyloid and Tangles are fibers of another protein called tau.” (Alzheimer’s Association, 2008, p.11);
Once it was believed that continuous exposure to metal, such as aluminum, was one of the causes of Alzheimer, but after years of studies, researchers have
