By then, the number of people with Alzheimer's disease will be 7.7 million, more than a 50% increase from the 5.1 million people ages 65 and over currently suffering from the disease. Because age is the most significant risk factor for Alzheimer's, efforts to develop effective therapies are more important than ever.
