Comparison of cerebrospinal fluid phosphorylated tau 181 and 217 for cognitive progression

A previous study demonstrated that cerebrospinal fluid (CSF) phosphorylated tau 217 (pTau217), compared to phosphorylated tau 181 (pTau181), correlated more strongly with Tau PET and was better able to distinguish between AD and non‐AD neurodegenerative diseases. The aim of this study was to compare these two CSF tau markers for cognitive progression.
