In order to compare the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA), one study administered both tests to 413 patients and compared the results.2 Scores on both tests were correlated.2 However, in patients who scored relatively normally on the MMSE, scores on the MoCA were correlated with higher Rankin scores, and deficits in delayed recall, abstraction, visuospatial/executive function, and sustained attention, suggesting that the MoCA was more sensitive to cognitive dysfunction after stroke in these patients.2
