When ADNI participants with no signs of abnormal tau or atrophy were included in the analyses (i.e., the A−T−[N]− and A+T−[N]− subgroups; n = 275), an association was again found only between abnormal Aβ status and worse performance on the executive measure (β = 0.143, 95% CI 0.023–0.262; p = 0.019); increasing CSF p-tau181 levels were associated with worse memory performance (β = 0.180, 95% CI 0.066–0.293; p = 0.002). Here, MAPT is linked to Atrophy.
