Occasionally scan QC and scan information records which should be linked are not linkable because of discrepant data (e.g. exam dates do not match). The NV data code will be used in these cases as well, until the discrepancies are corrected.

<		 A: Item level scores are currently available in the adni_adas file. We have had some technical issues with the release of the ADAS-Cog total scores but we hope to have the scores available through LONI very soon. Please let us know if you are in desperate need of the scores and we will try to get them to you in some other way. If possible, it would be better to wait for the release through LONI, of course, as you would then be able to download a complete version of the live database and you could be sure you are not missing any scores, and that you are dealing with contemporaneous data, etc.
