Before submitting a request, you are urged to familiarize yourself with the UDS study population and bear its limitations in mind when you formulate your research question and interpret your data.
To submit a data request, please provide the contact information requested on this page, and complete the survey on the following page. Note that investigator name, institution, project title, and aims will be displayed in the list of Ongoing and Completed Proposals on the NACC website.
NACC cannot ensure that each set of proposal aims 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 existing proposals.
