Question Posted 05/24/18:
In the Diagnostic Summary [ADNI1,GO,2,3] database, only ADNI1 has DXCONTYP data. I was wondering if there are more DXCONTYP data for ADNIGO,2,3; if so, where could I find them?
Response posted 05/24/18 by Danielle:
The way in which diagnosis information was captured changed during the different phases of ADNI. In ADNI-GO/2 refer to the DXCHANGE variable and in ADNI-3, refer to the DIAGNOSIS variable (both in the Diagnostic Summary where you found DXCONTYP). The Data Dictionary defines the coding.
