Alzheimer’s Disease: Introduction

Did you know?

The Alzheimer's Association has released a 2009 Alzheimer's Disease Facts and Figures report. One major finding of the report is that annual health care costs are over three times greater for individuals with Alzheimer's compared to elderly individuals without Alzheimer's ($33,007 vs. $10,603).

What Is Alzheimer’s Disease?

Alzheimer’s disease (AD) is an irreversible disease of the brain that affects a person’s memory, thinking, and other abilities.

How Common Is Alzheimer’s Disease?

Alzheimer’s disease is the most common form of dementia in people age 65 and over. Over 5.2 million Americans are estimated to have Alzheimer’s disease. By 2050 this number is expected to reach 11 to 16 million (Alzheimer’s Association, 2009).

How the Brain Changes With Alzheimer’s Disease

Alzheimer’s disease is a progressive disease, meaning that it gets worse and more functions are lost as more time passes. Some studies suggest that Alzheimer’s disease may begin attacking the brain long before symptoms are present. The disease first attacks the memory center of the brain, which causes people with AD to become more forgetful. As the disease progresses, the person may also begin to have other problems, such as problems with thinking and walking.

Alzheimer’s Disease Is NOT a Normal Part of Aging

Despite what some people think, getting Alzheimer’s disease is not a normal part of aging. However, it is true that people are more likely to develop AD as they grow older. There is no cure for AD, but there are multiple treatments that can slow down the progression of the disease. Researchers believe that an individual who is diagnosed with AD at age 65 may live an average of 8-10 years (Alzheimer’s Disease Research, 2009). Although an individual older than 80 may only live 3 or 4 years after being diagnosed (NIA 2010).
