Table 1 Demographic and clinical data, scores for the cognitive tests and biomarkers analyses. MMSE: Mini Mental State Examination; RBANS-DMI: Repeatable Battery for the Assessment of Neuropsychological Status-Delayed Memory Index. Protein expression levels of biomarkers in the CSF of participants. Cut-off points to define positivity for AD: Aβ₁₋₄₂ < 638 pg/mL; total (t)-tau > 404 pg/mL; p-tau 181 > 52.1 pg/mL; t-tau/ Aβ₄₂ > 0.784; Aβ₁₋₄₂/Aβ₁₋₄₀ < 0.068. [9]
