Nevertheless, neuroimaging and biomarker studies show consistencies in the sequential onset of amyloid deposition, tau, FDG-PET hypometabolism, grey matter atrophy, and clinical presentation between late-onset and autosomal-dominant Alzheimer’s disease (Bateman et al., 2012; Benzinger et al., 2013; Young et al., 2014; Gordon et al., 2018; Oxtoby et al., 2018), suggesting substantial commonalities between both sporadic late-onset and genetically caused Alzheimer’s disease. This evidence concerns the gene MAPT and early-onset autosomal dominant Alzheimer disease.
