ADNI Data

The ADNI data set is a comprehensive and widely used collection of longitudinal clinical, imaging, genetic, and other biomarker data. It encompasses various data types, including structural, functional, and molecular brain imaging, biofluid biomarkers, cognitive assessments, genetic data, and demographic information.

ADNI participants are assigned to a Schedule of Events (SOE) based on various factors, such as clinical diagnosis (unimpaired, MCI, AD/dementia). During each visit, the SOE dictates what data is collected. This data is made available to approved researchers.

To Access ADNI Data

All ADNI data are shared through the LONI Image and Data Archive (IDA), a secure research data repository. Interested scientists may obtain access to ADNI imaging, clinical, genomic, and biomarker data for the purposes of scientific investigation, teaching, or planning clinical research studies. Access is contingent on adherence to the ADNI Data Use Agreement and the publication policies outlined in the documents listed below.

Data from several dementia studies complementary to ADNI are also available through the IDA. The most comprehensive ADNI genomics and related -omics data can be accessed through external databases, such as NIAGADS and NACC, which compile data from various projects and have their own access and approval processes.

Apply For Data Access

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

Application Review

The ADNI Data Sharing and Publications Committee (DPC) generally reviews data use applications within two weeks of submission. Each application is carefully reviewed to verify 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 and Data Archive (IDA).

Maintaining Your ADNI Data Use Account

A provision of the ADNI Data Use Agreement requires submission of 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. Login to update your account information.
