Regarding cellular tau pathology (Supplementary Figure 2), the PSP-Cx group showed higher total and cortical neuronal tau burden than PSP-P (p < 0.05) and higher neuronal, astroglial and oligodendrocyte cortical tau burden than PSP-RS/PI (p < 0.05). This evidence concerns the gene MAPT and supranuclear palsy, progressive, 1.
