Alzheimer’s Disease Fact Sheet

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. In most people with Alzheimer’s,symptomsfirst appear in their mid60s. Estimates vary, but experts suggest that over 5.5 million Americans may have Alzheimer’s. It is the most common cause of dementia among older adults with the loss of cognitive functioning—thinking, remembering, and reasoning — and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

The causes of dementia can vary, depending on the types of brain changes that may be taking place over time. Dementias include Lewy body dementia, frontotemporal disorders, and vascular dementia, for instance. It is common that over half patients have mixed dementia episode —a combination of two or more disorders. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness.

Her symptoms included over ten different manifestations, among which memory loss, language problems, and unpredictable behavior were stronger. After she died, he examined her brain and found many abnormal clumps — now called amyloid plaques — and tangled bundles of fibers — now called neurofibrillary. These plaques and tangles in the brain are still considered some of the main features of Alzheimer’s disease.

Another one is the loss of connections between nerve cells (neurons) in the brain. Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body. Scientists continue to unravel the complex brain changes involved in the onset and progression of Alzheimer’s disease.

It seems likely that damage to the brain starts a decade or over before memory and other cognitive problems appear. During this preclinical stage of Alzheimer’s disease, people seem to be symptom-free, but toxic changes are taking place in the brain. The first symptoms of Alzheimer's vary from person to person. For many, decline in non-memory aspects of cognition, such as word-finding, vision/spatial issues, and impaired reasoning or judgment, may signal the very early stages of Alzheimer’s disease.

As Alzheimer’s disease progresses, people experience greater memory loss and other cognitive difficulties. Problems can include wandering and getting lost, trouble handling money and paying bills, repeating questions, taking longer to complete normal daily tasks, personality and behavior changes. People are often diagnosed in this stage. Scientists don’t yet fully understand what causes Alzheimer’s disease in most people.

There is a genetic component to some cases of early-onset Alzheimer’s disease. Late-onset Alzheimer's arises from a complex series of brain changes that occur over decades. The causes include a combination of genetic, environmental, and lifestyle factors. The importance of any one of these factors in increasing or decreasing the risk of developing Alzheimer’s may differ from person to person.
