Alzheimer's is the most common form of dementia seen in older people. Memory loss, confusion, and impaired judgment are typical symptoms. Named after a German physician, Dr. Alois Alzheimer, the disease affects approximately 5 percent of people ages 65 to 74. While treatments exist to help improve symptoms, currently there is no cure. Although Alzheimer's disease is not a normal part of aging, people become more likely to develop the condition as they get older.
