WebApr 9, 2024 · Plasma p-tau217 was more strongly correlated with brain β-amyloid and paired helical filament tau (PHFtau) tangles than p-tau181. Both p-tau markers were associated with greater odds of AD, but p-tau217 had higher accuracy (area under the ROC curve (AUC): 0.83) than p-tau181 (AUC: 0.76). WebJan 9, 2024 · Cerebro-spinal fluid (CSF) total tau (T-tau) has been suggested as a general marker of neurodegeneration [ 4 ], while phosphorylated tau (P-tau) may be a more specific marker for AD because neurofibrillary tangles primarily consist of tau protein in the abnormally hyperphosphorylated state [ 5 ].
