Please note that before receiving a data file you will be asked to acknowledge the
NACC Data Use Agreement.

Before submitting a request, you are urged to familiarize yourself with the UDS study population and to bear its limitations in mind when you formulate your research question and interpret your data.

Please provide the information requested below, and then click SUBMIT. You will be contacted by a NACC staff member within two business days. Data files are generally provided in less than a week from the time in which the criteria for the file are fully specified by the investigator. Note that investigator name, institution, email address, title, abstract, and key words will be displayed on the Researchers page on the NACC website.

NACC cannot ensure that each data request and resulting data set are novel to the NACC database. It is the responsibility of the researcher, not NACC, to identify a unique research hypothesis and ensure that there is no significant overlap with other ongoing or published NACC data analyses.
