“…In the present analysis, prediction of MoCA scores from MMSE data was also less accurate. Overall, the MMSE‐MoCA conversion table presented here replicates existing tables for clinically heterogeneous samples with different neurodegenerative 17,24 and neurological diseases 3 . As previously reported, 3,17 the distribution of MoCA and MMSE scores was left‐skewed, indicating the comparatively lower number of patients with severe cognitive impairment.…”

“…Another point to mention is, that the majority of existing studies provide conversion tables for specific patient populations 12–14,16,18–19,27,36 . This is based on the assumption that the association between MoCA and MMSE is expected to differ between patients with primarily mnestic disorders and patients with executive dysfunction, since executive functions are not assessed in the MMSE 13,17,24 . It is possible that etiology‐specific conversion tables are more reliable when the cause of the cognitive disorder is known 24 .…”

“…16 Other studies did not mention whether extrapolations have been made in the lower score range to correct for scarcity of data. 9,12,[14][15][18][19]21,[23][24][26][27][28] Second, different statistical conversion methods have been used. Scale equating using linear regression analysis does not adequately represent test-to-test differences in difficulty that vary along the scores, 9,27 which can reduce prediction accuracy, particularly in the lower and upper score ranges.…”

“…17 Moreover, only a few studies considered a bi-directional score equation. 17,[23][24][27][28] In most score conversion studies the uni-directional MoCA to MMSE translation was performed, 3,9,[12][13][14][15][16][19][20][21]26 which leads to gaps and overrepresentations in the MMSE score range, making it difficult to unambiguously assign an equivalent MoCA score. 18 Specifically, it was found that multiple MMSE scores could correspond to one MoCA score at higher levels of cognitive function, while one MMSE score could correspond to multiple MoCA scores at lower levels of cognitive function.…”

“…Thus, conversions are needed that reflect the relationship between MoCA and MMSE for a broad range of causes of cognitive impairment as (a) patient populations are usually heterogeneous; (b) the cause of cognitive impairment during screening is unclear; and (c) comorbid diseases and conditions are often present 17 . Moreover, only a few studies considered a bi‐directional score equation 17,23–24,27–28 . In most score conversion studies the uni‐directional MoCA to MMSE translation was performed, 3,9,12–16,19–21,26 which leads to gaps and overrepresentations in the MMSE score range, making it difficult to unambiguously assign an equivalent MoCA score 18 .…”

Background: Early and accurate detection of cognitive changes using simple tools is essential for an appropriate referral to a more detailed neurocognitive assessment and for the implementation of therapeutic strategies. The Mini- MentalStatus Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) are two commonly used psychometric tests for cognitive screening. Both tests have different strengths and weaknesses. Preferences regarding test selection may therefore differ among clinicians. The aim of this retrospective observational cohort study was to define corresponding scores for the MMSE and the MoCA.Methods: We examined the relationship between the cognitive screening tests in 803 German-speaking Memory Clinic outpatients, encompassing a wide range of neurocognitive disorders. We produced a conversion table using the equipercentile equating method with log-linear smoothing. In addition, we conducted a systematic review of existing MMSE-MoCA conversions to create a table allowing for the conversion of MoCA scores into MMSE scores and vice versa using the weighted mean method. Results: The Memory Clinic sample showed that the prediction of MMSE to MoCA was overall less accurate compared to the conversion from MoCA to MMSE. The 19 studies included after thorough literature search showed that MoCA scores were consistently lower than MMSE scores. Eleven of 19 conversion studies had addressed the conversion of the MoCA to the MMSE, while two studies converted MMSE to MoCA scores. Another six studies applied bidirectional conversions. We provide an easy-to-use table covering the entire range of scores and taking into account all currently existing conversion formulas.Jael S. Fasnacht and Alexandra S. Wueest contributed equally to this study.

There are controversial data about the effect of carotid endarterectomy regarding postoperative cognitive function. Our aim was to analyze the effect of cerebral tissue saturation monitored by near-infrared spectroscopy (NIRS) on cognitive function. Perioperative data of 103 asymptomatic patients undergoing elective carotid surgery under general anesthesia were analyzed. Preoperatively and 3 months after the operation, MMSE (Mini Mental State Examination) and MoCA (Montreal Cognitive Assessment) tests were conducted. For cerebral monitoring, NIRS was used, and the lowest rSO2 value and the degree of desaturation were calculated. Cognitive changes were defined as one standard deviation change from the preoperative test scores, defined as postoperative neurocognitive decline (PNCD) and cognitive improvement (POCI). PNCD was found in 37 patients (35.92%), and POCI was found in 18 patients (17.47%). Female gender, patients with diabetes, and the degree of desaturation were independently associated with PNCD. The degree of desaturation during the cross-clamp period negatively correlated with the change in the MoCA scores (R = − 0.707, p = 0.001). The 15.5% desaturation ratio had 86.5% sensitivity and 78.8% specificity for discrimination. For POCI, a desaturation of less than 12.65% had 72.2% sensitivity and 67.1% specificity. POCI was associated with lower preoperative MOCA scores and a lower degree of desaturation. We found a significant relation between the change of postoperative cognitive function proven by the MoCA test and cerebral tissue saturation during the clamping period in patients undergoing carotid endarterectomy.
