In DLB/AD+, MRI shows hippocampal atrophy and 18F-FDG PET hypometabolism in the MTL [61], while 18F-florzolotau PET imaging elucidates tau pathology patterns in DLB, with 54% showing patterns similar to AD, whereas 16% exhibit distinct patterns [204]. This evidence concerns the gene MAPT and Alzheimer disease.
