What’s the difference between the ADNI 1, ADNI GO, ADNI 2 and ADNI 3 studies?

Although the four studies all aim to advance AD research, you will find differences in participant pools, and adjustments to data collection protocols over time as a result of scientific findings and changing technologies. These differences are outlined in the  Study Objectives , and the Data & Samples sections for each core. For instance, DTI data is available from some ADNI GO and ADNI 2 subjects, as this is fairly new technology. ADNI manuals, procedures are protocols from each study are available on the  ADNI Documents: Procedures, Protocols, and Manuals webpage for download. Visit the ADNI 3 page to learn more about what’s new in ADNI 3.

How can I acknowledge/cite the ADNI data/protocols?

Acknowledgement requirements are detailed in the Data Sharing and Publications Policy. This and other relevant documents can be found on the webpage, “How to Apply for Data“.
