Objectives: Analysis of reliability of the Polish version of the MoCA 7.2 vs. the MMSE in mild NCD detecting, while taking into consideration the sensitivity and specificity of cut-off points for each type of education.
Methods: Cross-sectional study was conducted at the Department of Geriatrics, Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Torun. The study was conducted between September 2014 and December 2015. The study involved 131 participants, including 54 people assigned to the group without NCD and 77 to the group with mild NCD. Recruitment for both groups was performed on the basis of specific inclusion and exclusion criteria.
Results: Mean scores of the MoCA 7.2 and the MMSE showed a statistically significant difference between the groups with and without mild NCD. The optimal cut-off point on the MoCA scale for mild NCD was 24/25. The optimal cut-off point on the MMSE scale for mild NCD was 28/29. In the ROC curve analysis, area under the curve (AUC) for the MoCA was significantly greater than the AUC for the MMSE.
Conclusions: The MoCA 7.2 detect mild NCD with greater sensitivity than the MMSE. In the case of this tool, we propose the use of 24/25 cut-off point which has a higher sensitivity than the recommended 25/26 cut-off point. The MoCA 7.2 therefore can be used by primary healthcare and in the geriatric practice as a screening tool in detecting early cognitive impairment.
