Research on the causes and treatments of dementia, including Alzheimer's, is ongoing. Among those committed to the cause is the Wisconsin Alzheimer's Institute at the University of Wisconsin School of Medicine and Public Health. "The primary focus of WAI research is the prevention of Alzheimer's," the site explains. "Our internationally recognized research program, the Wisconsin Registry for Alzheimer's Prevention, known more familiarly as WRAP, holds tremendous promise for demystifying the biologic origins of Alzheimer's. The WRAP study is the first and crucial step toward prevention and early intervention. Started in 2001, WRAP is the largest study of its kind enrolling more than 1,500 adult children of parents with Alzheimer's representing diverse communities and populations."
