In addition, the findings of tau PET imaging in the present case may not necessarily be PART-like, since the radio signals of 18F-florzolotau were seen in the left superior and middle temporal gyrus, left supramarginal gyrus, and left frontal operculum, whereas those in the preclinical stage of AD or PART may expand from the medial temporal cortex, involving less-mature tau fibrils, to the other neocortical and limbic areas, along with the progression of the NFT stage (22). The gene discussed is MAPT; the disease is Alzheimer disease.
