Fig. 1

Scatterplots for MMSE and MoCA scores shown by diagnostic group. Graphs are for all subjects (a), dementia only (b), MCI only (c) and HC only (d). Pearson correlation coefficients between MMSE and MoCA scores are shown for each graph. Vertical lines denote MMSE standard cutoff of 24 points and horizontal lines denote different proposed MoCA cutoffs for MCI (17, 19 and 23). Note that symbols may represent more than one case at that score
