NACC data summary reports

The data captured in the NACC database require in-depth understanding of the individual data elements. To avoid spurious and misleading conclusions based on random associations, NACC recommends a free consultation with one of our research scientists at

Custom queries and data files

To perform a web-based query of the UDS, NP, and FTLD databases and generate tables with specified selection criteria, please go to NACC's web-based query system.

If neither the summary reports available at left nor the direct query system mentioned above meet your research needs, you may request a custom data file, tailored to your research question.

If you have any questions, or if you need to expedite a request for a custom data file (e.g., in order to meet a grant application deadline), please contact NACC at
