Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is 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.
