Question Posted 02/12/18:
How do I determine the normal subjects in ADNI2? There is an FAQ answering eMCI but there is nothing that talks how to find normal subjects.

Please refer to the Diagnostic Summary file available for download on the Study Data page. You can use the variable DXCHANGE to identify the different diagnostic groups. The Data Dictionary file contains the coding for this variable.
