Hello,

If I'm correct the file ADASSCORES.csv contains a summary of the ADAS assessment in particular the ADAS-Cog (TOTAL11) and modified ADAS-Cog (TOTALMOD) scores but only for ADNI1 (it has the same subjects and viscodes than in ADAS_ADNI1.csv). I guess it has been computed from ADAS_ADNI1.csv. The answers for ADNIGO/ADNI2 are in ADAS_ADNIGO2.csv.

How can I access the ADAS-Cog and modified ADAS-Cog scores for ADNIGO/2? Is there a column in ADAS_ADNIGO2.csv or should I compute them?

Thanks in advance,
Mathieu

The adnimerge table has the 11 and 13 item versions of ADAS totals (ADAS11 and ADAS13) across all phases of ADNI. The table is located at "Study Info" > "Key ADNI tables merged into one table" > "Key ADNI tables merged into one table". 

The adnimerge table is also included in the R, SAS, Stata, and SPSS packages.

Hi Mike,

thanks for your answer. I will look into this file.

Are those scores computed in the adnimerge R package?

Mike
