Nearly 5.3 million Americans are living with Alzheimer’s disease, and 26.6 million people are affected worldwide. The Alzheimer’s Disease Neuroimaging Initiative (ADNI), a public-private partnership, provides a publicly available, international database of clinical and imaging data to foster research and collaboration on Alzheimer’s research worldwide. The Institute of Medicine held a workshop on July 12, 2010, to explore opportunities to use information from and partnerships formed because of ADNI to continue to improve the understanding and treatment of Alzheimer’s disease.
