Although the diagnostic accuracy of MoCA is comparable to that of the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) and Quick Mild Cognitive Impairment (Qmci) [50], our previous study showed that MoCA-J had excellent sensitivity and specificity in diagnosing MCI when the cut-off value similar to this study was used [32]. This evidence concerns the gene DOCK3 and Cognitive impairment.
