Open Access Series of Imaging Studies (OASIS-2)
OASIS is a project aimed at making neuroimaging data sets of the brain freely available to the scientific community. OASIS currently contains 4 datasets (OASIS-1, OASIS-2, OASIS-3, and OASIS-4). OASIS-2 is the "Longitudinal MRI Data in Nondemented and Demented Older Adults" dataset and includes 150 participants aged 60 to 96 years, many of whom were diagnosed with Alzheimer's disease at some point during their participation. Participants were obtained from the longitudinal pool of the Washington University Alzheimer Disease Research Center (ADRC). Each participant was scanned on two or more visits, separated by at least one year, for a total of 373 imaging sessions.
