Exclusion criteria applied to both groups were a score below 26 in the Montreal Cognitive Assessment (MoCA) (Freitas et al. The exclusion criteria were chosen, so that no other neurological disease and no disorder of the peripheral olfactory and gustatory system could influence the test results. In conclusion, both versions of the MoCA are valid, reliable, sensitive and accurate screening instruments for VaD patients.
#Moca testing full version
With a cutoff below 17 on the MoCA full version and 8 on the short version, the results for sensitivity, specificity, positive and negative predictive values, and classification accuracy were superior compared to the MMSE.
Both the full and short versions of the MoCA had excellent diagnostic accuracy in discriminating VaD patients, exhibiting an area under curve (AUC) higher than the MMSE. The results, based on a homogeneous sample of 34 VaD patients, indicate that the MoCA is a psychometrically valid and reliable instrument for cognitive screening in VaD patients, showing excellent discriminant validity. The aim of the present study was to validate the MoCA as well as its short version, which was proposed by the NINDS-CSN VCI Harmonization Standards for screening Vascular Dementia (VaD) patients. The Montreal Cognitive Assessment (MoCA) is a brief instrument developed for the screening of milder forms of cognitive impairment, having surpassed the well-known limitations of the MMSE.
