Misplacing car keys. Not remembering a familiar name. Some people do become more forgetful as they get older. That's a normal part of aging. Alzheimer's disease is not.

Alzheimer's disease affects approximately 4.5 million people in the U.S. Over time, Alzheimer's disease gradually destroys a person's memory and ability to learn and carry out daily activities such as talking, eating, and going to the bathroom. As the disease progresses, individuals may also experience changes in personality and behavior. Unfortunately, there are no cures for Alzheimer's disease and there is no way to predict how fast someone will progress through the stages of the disease.

However, early Alzheimer's diagnosis and treatment can slow the progression of Alzheimer's symptoms. If you or someone you are caring for is suffering from Alzheimer's disease, you may want to talk with the doctor.
