We found that SCC was frequently positive for tau pathology (11/12, 92% in AD vs. 7/16, 44% in PART) in both AD and PART brains, and was even positive in early PART with Braak stage I. No tauopathy was observed in the cerebellum/dentate nuclei in our PART and AD brains. This evidence concerns the gene MAPT and tauopathy.
