Similarly, tau pathology is also seen in post encephalitic parkinsonism (172), Niemann-Pick type C disease (173) subacute sclerosing panencephalitis (SSPE) (174) and in prion disease like Gerstmann-Straussler-Scheinker disease (GSS) (175) although the clinico-pathological significance is still unknown. Here, MAPT is linked to subacute sclerosing panencephalitis.
