ALZHEIMER'S

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 Alzheimer’s disease in the century since Dr. Alzheimer first drew attention to it. Today we know that Alzheimer’s:

Is a progressive and fatal brain disease. More than 5 million Americans now have Alzheimer’s disease. Alzheimer's destroys brain cells, causing problems with memory, 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. For more information, see Symptoms or Stages of Alzheimer’s Disease.

It is the most common form of dementia, a general term for the loss of memory and other intellectual abilities serious enough to interfere with daily life. Vascular dementia, another common type of dementia, is caused by reduced blood flow to parts of the brain. In mixed dementia, Alzheimer’s and vascular dementia occur together. For more information about other causes of dementia, please see Related Dementias.

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. We’ve learned most of what we know about Alzheimer’s in the last 15 years. There is an accelerating worldwide effort under way to find better ways to treat the disease, delay its onset, or prevent it from developing.
