Submit data request
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.
There are two ways to request NACC data for research:
Quick-access full data file
Your data set is usually available for download within one business day of your request. With this request, you receive the complete UDS, Neuropathology, and APOE/genetic data sets from the latest quarterly data archive.
Custom data request
If you require restricted inclusion criteria or additional data sets beyond the complete UDS, Neuropathology, and APOE/genetic data sets included in the quick-access file, you may request a custom data set. This method requires a longer time before your data is available for download.
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.
