Aβ42: -, negative; +, small aggregates of Aβ42 were observed in the parietal and temporal cortices on FA-pretreated sections, and intracellular aggregates of Aβ 42 were observed in the cytoplasm of hippocampal pyramidal cells. HP-tau: -, negative; +, AT8-positive cells limited to the entorhinal cortex; ++, AT8-positive cells in the entorhinal cortex and throughout the hippocampus. F, female; M; male, ND, no data; a, weak AT8 positivity on the surface of cerebral cortex
