EMCI vs LMCI

You will find the definition of EMCI and LMCI on pages 27-28 of the ADNI-2 Procedures Manual (http://adni.loni.usc.edu/methods/documents/) – this table gives the inclusion criteria for the different groups.
You can link the DTI data (by RID) to the Diagnostic Summary file (DXSUM_PDXCONV_ADNIALL.csv) to get information on changes in diagnosis.

Hi Rochelle,
During ADNI-1, all diagnosis information was contained in a set of variables (see DATADIC.csv, the data dictionary for coding of these variables):
DXCURREN captured current diagnosis
DXCONV captured whether a conversion or reversion in diagnosis occurred
DXCONTYP captured the type of conversion
DXREV captured the type of reversion
So, you would generally use DXCONV and DXCONTYP to identify those that converted from MCI to dementia.
In ADNI-GO/ADNI-2, all diagnosis information (including reversions and conversions) is captured in DXCHANGE (again, refer to the DATADIC.csv file for coding information).

Hi ADNI users,
can anyone explain what it the difference between early-MCI subjects and late-MCI subjects? I can't find a document that explains this grouping. Is there any difference in any of the cognitive tests/abilities, subjective memory complaints etc.?
Also, there used to be a grouping based on conversion to AD over time (MCI-converters vs MCI-non-converters). Is there anything like this available for the DTI data?
Thanks!

Hi All,
I am trying to analyse data in ADNI2 phase, and I tried to find the MRI data, in particular in DTIROI_04_30_14 file, but just about 200 patients up to 530 patients have the MRI data. Is it possible or Do you think I made something wrong when I merged the tables (by RID)?
Thank you in advance
