The Alzheimer's Association released some striking 2011 facts and figures that expose the huge toll Alzheimer's has taken on the U.S. Currently, 5.4 million Americans are living with the disease, but because of a high mortality rate, it's the 6th leading cause of death. Alzheimer's is the only cause of death in the top 10 (heart disease and cancer are the top two) that can't be prevented, cured or slowed. Whether a person with Alzheimer's is a patient in the hospital or lives at home, they will eventually need round-the-clock care, resulting in 17 billion hours of unpaid care by 15 million Alzheimer's caregivers every year. With a national cost of $183 billion annually, everybody should be concerned about finding a cure for this costly disease.
