Table 7.

Application of normative data to a separate longitudinal sample (n=151). Sensitivity and specificty were calculated at time of clinical diagnosis, based on Clinical Dementia Rating (CDR). Test scores normed using Robust Normal and Combined Samples. Classification accuracy was compared using the McNemar test.
