Launched in 2004, the Alzheimer’s Disease Neuroimaging Initiative (ADNI) has become a model of how public-private partnerships can lead to otherwise unattainable progress in biomedical research.  ADNI tracks more than 1000 subjects enrolled at 59 different clinical sites in the U.S. and Canada to study brain structure, function and biomarkers.  This 9 minute video follows Dr. Michael Weiner, M.D., ADNI Principal Investigator and Professor of Medicine, Radiology, Psychiatry and Neurology at the University of California, San Francisco as he enrolls as a subject in the ADNI clinical trial.
