What is Alzheimer disease?
Alzheimer disease is a disease that affects the brain. It is a common cause of dementia. Common symptoms include memory loss and impaired judgment. The symptoms of dementia progress over time. Most often people are older than 65 years old when they begin noticing symptoms of Alzheimer disease, but in some cases, the diagnosis comes earlier.
