The symptoms of Alzheimer's disease worsen over time, although the rate at which the disease progresses varies. On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors.
Overview. Alzheimer disease is a chronic, incurable brain disorder characterized by progressive loss of brain tissue and function. The early stages of Alzheimer disease primarily affect intellectual functions. Late-stage Alzheimer disease directly or indirectly affects other body systems. The condition is ultimately fatal. The Alzheimer's Association estimates that up to 5.3 million men and women in the United States are living with Alzheimer disease.
