About Alzheimer's disease
Alzheimer's disease, a leading cause of dementia, is a progressive brain disorder that gradually destroys a person's memory and ability to learn reason, make judgments, communicate and carry out daily activities. Alzheimer's disease may result from the build-up of toxic beta-amyloid peptides in the brain. As Alzheimer's disease progresses, individuals may also experience changes in personality and behavior, such as anxiety, suspiciousness or agitation, as well as delusions or hallucinations. It is currently estimated that more than 5 million Americans have Alzheimer's disease and more than 24 million people worldwide over the age of 60 have some form of dementia (Source: Alzheimer's Association and Alzheimer's Disease International).

Alzheimers disease is a degenerative brain disorder that primarily affects older people. It can begin with simple forgetfulness, but rapidly progresses into more advanced symptoms, including confusion, language disturbances, personality and behavior changes, impaired judgment and profound dementia. As the disease advances, most patients will eventually need complete skilled nursing care, and in the absence of other illnesses, the progressive loss of brain function will likely cause death. It is estimated that more than 5 million Americans and more than 24 million people worldwide, at the age of 60 years or older, suffer from some form of dementia.
