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.
These data are to be used for informational purposes only. Any effort to determine the personal identity associated with any reported data is prohibited. Distribution or release of data or image files obtained from the National Alzheimer's Coordinating Center to third parties is prohibited.
