What is Alzheimer’s disease?
Alzheimer’s is a type of dementia that affects memory, thinking, and behavior. Symptoms eventually grow severe enough to interfere with daily tasks.
Alzheimer’s is the most common cause of dementia, a general term for memory loss and other cognitive abilities severe enough to interfere with daily life.
Alzheimer’s disease accounts for 60-80% of dementia cases.
Alzheimer’s is not a normal part of aging. The most significant known risk factor is increasing age, and the majority of people with Alzheimer’s are 65 and older.
On average, a person with Alzheimer’s lives 4 to 8 years after diagnosis but can live as long as 20 years, depending on other factors.
