The prediction of outcome after ischemic stroke (IS) is currently based on indirect data from clinical and radiological evaluation. We evaluated the usefulness of serum Tau protein as possible prognostic markers for IS. Fifty-six patients with computed tomography-confirmed IS were enrolled. ⋯ Patients in whom Tau protein was detected in serum, when compared with patients without Tau protein, developed more severe neurological deficits, had worse functional status measured in the early and late phase of IS, and were found to have larger volume of infarction. However, Tau protein concentrations measured within the early phase of IS did not correlate with degrees of neurological deficit and disability in the early phase and also after 3 months of IS. Detection of Tau protein in the serum of patients with IS but not its concentration can be considered as a bad prognostic factor for the clinical outcome in early and late phase of IS.
