Question Posted 09/10/17:
Hi

We are using ADNI DTI data for our research purposes. I couldn\'t find any control data (volunteer?) using IDA Search (Simple search and Advance Search).

Please help us to get some Normal control DTI data from ADNI database.

Response posted 09/15/17 by Susan Landau:

Subject diagnosis at each visit is recorded in several CSV files in the Download --> Study Data section. Initial diagnosis is recorded in the ARM.csv file (ADNI1/GO/2 only) and diagnosis at subsequent visits appears in the DXCURREN, DXCHANGE or DIAGNOSIS variables (depending on the phase of ADNI) in the Diagnostic Summary CSV file. You will need the Data Dictionary CSV file, also located in the Study Data section, to determine the mappings of the numerical variables to diagnostic information.
