Alzheimer's disease is the most common form of dementia. Dementia is a term that is used to describe a group of brain disorders. These brain disorders cause memory loss and make it harder to carry out daily tasks.
Alzheimer's disease develops slowly over time. The symptoms begin to appear so gradually that it is often mistaken for normal aging. Learn more about the Alzheimer's diagnosis, treatment options, and how to recognize the symptoms.
