Information used to calculate Z scores with sociodemographic variables for the MoCA total score

Equations to calculate Z scores

Z = (Real score − Expected score) / Square root of the mean square residual

Z = (Real score − (25.186–0.083 A + 0.785 E–0.590 S – 0,019 E × E)) / 2.29

Note: E = Education in years; A = Age in years; S = Sex (0 = women and 1 = men).
