The effects of age and sex on plasma p‐tau181 concentrations in Alzheimer’s Disease

Quantifying levels of phosphorylated tau in plasma is a highly promising and specific marker for Alzheimer’s disease (AD), but limited data are available on the effect of age on plasma p‐tau181 concentrations in specific clinical groups and especially control subjects. Similarly, the effect of sex on concentration of plasma ptau‐181 levels are unclear.
