Alzheimer's Disease Definition

Alzheimer’s disease is a brain disorder named for German physician Alois Alzheimer, who first described it in 1906. Scientists have learned a great deal about it in the century since Dr. Alzheimer first drew attention to it. Today we know that Alzheimer’s:

• Is a progressive and fatal brain disease. As many as 5.3 million Americans are living with Alzheimer’s disease. Alzheimer's destroys brain cells, causing memory loss and problems with thinking and behavior severe enough to affect work, lifelong hobbies or social life. Alzheimer’s gets worse over time, and it is fatal. Today it is the seventh-leading cause of death in the United States.
•  Is the most common form of dementia, a general term for memory loss and other intellectual abilities serious enough to interfere with daily life. Alzheimer’s disease accounts for 50 to 80 percent of dementia cases. Other types of dementia include vascular dementia, mixed dementia, dementia with Lewy bodies and frontotemporal dementia.
• Has no current cure. But treatments for symptoms, combined with the right services and support, can make life better for the millions of Americans living with Alzheimer’s. There is an accelerating worldwide effort under way to find better ways to treat the disease, delay its onset, or prevent it from developing
