Patterns of cognitive impairment. Patterns of cognitive impairment in the progAβ-neg in A, stableAβ-neg in B and Aβ-pos in C groups. Note that only patients with impairment in at least two cognitive domains are represented here. The ‘x’ indicates that cognitive performance on that test was not impaired; empty cells indicate that the measure was not administered and coloured boxes indicate that performance on that test was impaired. The darker the colour, the higher the proportion of impaired patients in that measure in each group.
