This page describes longitudinal data sets, some of them publically available, some for participating investigators.

== ADNI ==

The Alzheimer's Disease Neuroimaging Initiative

Three stages (ADNI, ADNI-GO and ADNI2) exists with 800-1000 subjects and several time points approx. 6 months to a year apart.

== OASIS ==
Longitudinal MRI Data in Nondemented and Demented Older Adults

This set consists of a longitudinal collection of 150 subjects aged 60 to 96. Each subject was scanned on two or more visits, separated by at least one year for a total of 373 imaging sessions

== MIRIAD ==
Minimal Interval Resonance Imaging in Alzheimer's Disease 

The MIRIAD dataset is a database of volumetric MRI brain-scans of 46 Alzheimer's sufferers and 23 healthy elderly people. Many scans were collected of each participant at intervals from 2 weeks to 2 years and includes 708 scans.

== ELUDE ==
Efficient Longitudinal Upload of Depression in the Elderly

The ELUDE dataset is a longitudinal study of late-life depression at Duke University. There are 281 depressed subjects and 154 controls included. An MR scan of each subject was obtained every 2 years for up to 8 years (total of 1093 scans).
