Tau PET accumulation and MMSE in AD often do not correlate or require several efforts to find a correlation,47, 48, 49, 50, 51 but when the continuous amount of scores using the AD‐tau scoring system was examined, including HCs with even a single‐point decrease (MMSE score ≤ 29), a correlation was found even in MMSE, and the distribution of [18F]PM‐PBB3 accumulation expanded as the score increased (Fig. S3). Here, MAPT is linked to Alzheimer disease.
