CSF markers tau and p-tau and low a Beta

NEUROLOGY 2009;72:1056-1061

17 patients (10%) with low levels of Aβ1-42 and very high levels of tau and p-tau. More with moderate levels of tau were found, plus controls.

High tau and p-tau levels negatively correlated with category fluency and VAT test, not with other neuropsych tests (TMT A and B, digit span forward and backward).
