Question Posted 04/10/14:
Hello!I have some questions about the Study Data. First, I can not find any informantion of the \"DXSUM_PDXCONV_ADNIALL.csv\" in the Diagnostic Summary tables.It only contains one subject information .
Second,I can not find the \"ADNI_Complete3YearVisitList\" in the Data_Databaase file,where I could get this specific information?
Many thanks!

ADNI1 and ADNIGO/2 collected diagnosis summary information differently, so the DXSUM_PDXCONV_ADNIALL.csv is actually a combination of two tables (PDXCONV and DXSUM). To find definitions of the fields for records listed as ADNI1 (in the DXSUM_PDXCONV_ADNIALL.csv ), look in the ADNI Data Dictionary for the table PDXCONV. Alternatively, the fields for subjects listed as ADNI2 are defined under the table DXSUM. You will notice that records for subjects with data collected from ADNI1 will not have data in fields associated with DXSUM and vice versa.

Second, the Complete 3 Year data can be found in the Collections section of the Archive, under Shared Collections. Instructions to download that data is at the following link:
