MAPT and Mental deterioration: In the complementary analysis with continuous tau PET measures, baseline ERC FTP SUVR was significantly correlated with faster cognitive decline in cognitively impaired A− individuals (ADAS-Cog 11: r = 0.30; 95% CI, 0.15-0.53; P < .001), but not in cognitively unimpaired A− individuals (PACC-3: r = 0.03; 95% CI, −0.22 to 0.14; P = .63).
