What is Alzheimer’s Disease?

Alzheimer’s Disease is a neurological disorder in which the death of brain cells causes memory loss, as well as a decline in language, problem-solving and other cognitive skills. Alzheimer’s is a neurodegenerative type of dementia, which means that over the course of time there is progressive brain cell death, the total brain size shrinks, and brain tissue loses nerve cells and connections.

Alzheimer’s is the most common cause of dementia and is ultimately fatal. According to the Centers for Disease Control, death rates from Alzheimer’s are increasing, unlike those for heart disease and cancer.

The greatest risk factor for Alzheimer’s is age; most people with Alzheimer’s are diagnosed at age 65 or higher. Researchers believe that early detection will be the key to preventing, slowing and stopping the disease.

In 2015, an estimated 5.3 million people in the U.S. have Alzheimer’s. Of that number, 5.1 million are age 65 or older. About 33% of people 85 and older have the disease.
