Alzheimer

            The causes of Alzheimer's disease remain a mystery, but researchers have found that particular groups of people have risk factors that make them more likely to develop the disease than the general population.
             Many people do not realize how severe this disease really is. People also do not realize how much of a risk there is of developing the disease. Four million people in the United States today are afflicted with Alzheimer's Disease. Another very interesting fact about Alzheimer's Disease is that the changes in the brain take place 20 to 40 years before the patient shows any symptoms. About ten percent of Americans have this disease by the age of 65, and about 50 percent of Americans have the disease by the age of 85. People can live well into their 90s, and they still retain most of their memories and control of their bodies (Kahn, 1998). This is a disease that everyone all over the world should be concerned about.
