MAPT and dementia: In mice with dementia induced by amyloid β 1‐42 (Aβ 1‐42) injection, puerarin treatment increased the expression of brain derived growth factor (BDGF), glutathione‐S‐transferase (GST), and SOD, whereas it decreased phosphorylated‐Tau and ROS production in the hippocampus and cerebral cortex, resulting in a decrease of shrinking nuclei, and swollen, eccentrically dispersed neural bodies, and an improvement of both learning and memory in mice.55
