The overall sum of your Brain Test and the MMSE pointed to a statistically significant, positive correlation with moderate degree (r = 0.622, p <0.0001). The determinations of the cutoff points for the Brain Test, considering the normal classification detected by the MEEM test, were 72.0 points or more for elementary school, 80.5 points or more for high school, in relation to The cut-off point was attributed by interquartile range with a minimum of 85.0 points and a maximum of 88.0 points.
