Access Data

All ADNI data are shared without embargo through the LONI Image & Data Archive (IDA), a secure research data repository. Interested scientists may obtain access to the entirety of the ADNI imaging, clinical, genomic, and biomarker data for the purposes of scientific investigation, teaching or planning clinical research studies. Obtaining access to and using ADNI data requires adherence to the ADNI Data Use Agreement and the publication policies outlined in the documents listed below. Note: documents are subject to updates by ADNI.

Data from several dementia studies complementary to ADNI are also available through the IDA. These include the DoD-ADNI study (Effects of traumatic brain injury and post-traumatic stress disorder on Alzheimer’s disease in Veterans using ADNI) and the AIBL study (Australian Imaging Biomarkers and Lifestyle Study of Aging). More information about DoD-ADNI and AIBL may be found on the Collaborative Studies webpage.

Apply for Access to Data

The application process includes acceptance of the Data Use Agreement and submission of an online application form. The application must include the investigator’s institutional affiliation and the proposed uses of the ADNI data. ADNI data may not be used for commercial products or redistributed in any way.

Click on the buttons below to apply for ADNI data, DoD-ADNI data, AIBL data, or all three. Note: Each study has its own Data Use Agreement.

Application Review

The ADNI Data Sharing and Publications Committee (DPC) generally reviews data use applications within one week of submission. Each application is carefully reviewed to ensure investigator affiliation with a scientific or educational institution and on the basis of the proposed research or data use. Incomplete applications or those without a clear focus will not receive approval. The results of the Committee’s review will be sent via email. Approved applicants will receive login information to access and download ADNI data from the LONI Image & Data Archive (IDA).

Maintaining Your ADNI Data Use Account

A provision of the ADNI Data Use Agreement requires submission an annual update. Accounts will automatically expire if no update is submitted within the allotted time. You will receive an email reminding you that your annual update is due approximately one month before your account expires. You may also add or remove co-investigators, submit manuscripts and update contact information at that time or at any time in advance. Click here to login in and update your account information.
