Comparison of t-tau, p-tau and Aβ42 CSF concentrations between different groups. a Cognitively healthy (n = 27) and demented (n = 8) individuals (median levels 715 vs 472 pg/ml for Aβ42, 414 vs 427 pg/ml for t-tau and 63 vs 60 pg/ml for p-tau). b Individuals with mild (grades 1–2, n = 24) and severe (grades 3–4, n = 11) MTA (median levels 643 vs 715 pg/ml for Aβ42, 441 vs 401 pg/ml for t-tau and 64 vs 53 pg/ml for p-tau). No significant differences were observed between the groups for any of these biomarkers. Horizontal line on graphs indicates median levels. Dashed lines represent reference values
