You can extract the baseline diagnosis from LONI Download Study Data > Diagnosis > Diagnosis Summary (DXSUM_PDXCONV_ADNIALL.csv). For most individuals, the two diagnoses are the same, but the diagnosis did change for a handful of subjects. The diagnosis at the screening diagnosis was used to randomize individuals to an arm of the ADNI1 study (1.5T only, 1.5T + 3T, 1.5T + FDG-PET), but the diagnosis from the baseline visit is considered more accurate. Once a participant passed screening, the baseline assessment was conducted in which additional neuropsychological testing, imaging, and fluid samples were taken. Further explanation could be - (ADNI 1): Subjects who were randomized into the 3T scanner group had a 1.5T screening scan as part of the study inclusion/exclusion screening. Those subjects meeting inclusion criteria had a 3T scan at the Baseline visit.įOR SCREENING/BASELINE DIAGNOSIS: The screening visit consists of a subset of the planned assessments (neuropsychological testing, imaging, etc.) sufficient to evaluate the inclusion/exclusion criteria for each potential participant.
