MAPT and Alzheimer disease: Even though the proportions of AD‐P and FT‐P hypometabolism were found to be associated with Aβ deposition and Tau aggregation in this study, it cannot fully represent the accurate relationship between the hypometabolic pattern and AD pathological burden due to the high proportions of Aβ‐positive and Tau‐positive in this population, and more longitudinal studies are still needed to confirm it.
