NFTs in the BNM and the time interval from stroke to death. (a) In the 22 Braak stage I and II cases, the rate of the differences in the number of phosphorylated tau-immunoreactive (ptau+) neurons between BNM-affected and BNM-unaffected sides and was correlated with the time interval from stroke to death (r = 0.48, p = 0.02). (b) The rates of the number of GB+ neurons and the stroke–death interval were correlated (r = 0.69, p < 0.01). According to the logarithmic curves, NFTs increased during the 5–10 years following stroke onset until death
