(三) Alzheimer is considered an old people disease. It normally affects people more than sixty-five years old. However, a few rare cases have been discovered in people younger than forty. The average age of those found to have the disease is about eighty years old. Alzheimer disease is found in only about two percent of people who are sixty-five. But the risk increases to about twenty percent by age eighty. By age ninety, half of all people are found to have signs of the disease. Alzheimer affects people of all races equally. However, women are more likely than men to develop the disease. This is partly because women generally live longer than men. There is no simple test to tell if someone has Alzheimer disease. Doctors who suspect a person has the disease must test a patient for many other disabilities first. If the tests fail to show that other disabilities are responsible for the problems, then a doctor suspects that Alzheimer disease is responsible.
