What Causes Alzheimer’s:
Scientists don’t yet fully understand what causes Alzheimer’s disease. Recent research has shown that it develops because of a complex series of events that take place in the brain over a long period of time. It is likely that the causes include some mix of genetic, environmental, and lifestyle factors. Because people differ in their genetic make-up and lifestyle, the importance of any one of these factors in increasing or decreasing the risk of developing Alzheimer’s may differ from person to person.
