Datasets under this license
- OASIS-1
Structural brain MRI of adults across the age range, including older adults with very mild to moderate Alzheimer's disease, commonly used to study brain volume changes with age and dementia. 416 people aged 18 to 96, 100 with dementia, with averaged images and tissue segmentations.
- OASIS-2
Repeated structural brain MRI of older adults without dementia or with very mild to mild Alzheimer's disease, used to study brain volume loss in ageing and early dementia. 150 people aged 60 to 96 scanned at two or more visits, 373 sessions in total.
- OASIS-3
Brain MRI, amyloid, FDG and tau PET and clinical follow-up of cognitively normal and declining adults, gathered over three decades for research on ageing and preclinical Alzheimer's disease. About 1,378 people aged 42 to 95 from Washington University in St. Louis.
- OASIS-4
Brain MRI with clinical, CSF and neuropsychological data of people evaluated for memory problems and dementia at a clinic in St. Louis. 663 people aged 21 to 94 with 676 MRI sessions; a separate cohort, not a newer version of OASIS-3.
