Question Posted 03/13/17:
Dear Experts,
I am trying to compare spreadsheets within the ADNIDOD database, and was seeking some clarification on the different IDs between subjects. For example, when trying to match subjects' neuropsychological assessment data with their cohort from the VAELG spreadsheet, should SCRNO be used? It seems that the other IDs change between spreadsheets, but could not find more information regarding the naming convention within the data dictionary. Thank you!

The best participant ID to use for ADNI DOD is SCRNO. This can be found in all of the spreadsheets and remains the same for a participant across visits.
