The Uniform Data Set contains longitudinal data, collected since 2005 during standardized annual evaluations conducted at the NIA-funded Alzheimer’s Disease Research Centers (ADRCs) across the country. Participants in the study represent the entire Clinical Core enrollment of the ADRCs, with cognitive status ranging from demented to mild cognitive impairment to cognitively normal. A subset of UDS participants are also evaluated with one of the additional sets of diagnosis-specific data-collection forms, the FTLD Module or the LBD Module.
Essential Documents
The 2012 and 2013 UDS v2 guides were previously recommended to researchers using NACC data. These files are still available to support researchers who are using NACC data sets cut before the introduction of the more comprehensive Researchers Data Dictionary (UDS-RDD), introduced in 2015.
