However, significantly lower levels of the CSF Aβ42 and p-tau were observed in the probable NPH group compared to the normal controls (444.22 ± 163.3 vs. 1213.75 ± 556.5 pg/mL, p < 0.001; and 26.05 ± 9.2 vs. 46.16 ± 13.3 pg/mL, p < 0.001; respectively). The gene discussed is MAPT; the disease is normal pressure hydrocephalus.
