The Montreal Cognitive Assessment (MoCA) is a cognitive screening instrument developed to detect mild cognitive impairment (MCI). It is a simple 10 minute paper and pencil test that assesses multiple cognitive domains including memory, language, executive functions, visuospatial skills, calculation, abstraction, attention, concentration, and orientation. Its validity has been established to detect mild cognitive impairment in patients with Alzheimer’s disease and other pathologies in cognitively impaired subjects who scored in the normal range on the MMSE. MoCA’s sensitivity and specificity to detect subjects with MCI due to Alzheimer’s disease and distinguish them from healthy controls are excellent. MoCA is also sensitive to detect cognitive impairment in cerebrovascular disease and Parkinson’s disease, Huntington’s disease, brain tumors, systemic lupus erythematosus, substance use disorders, idiopathic rapid eye movement sleep behaviour disorder, obstructive sleep apnoea, risk of falling, rehabilitation outcome, and epilepsy. There are several features in MoCA’s design that likely explain its superior sensitivity for detecting MCI.
In contrast, the short variant by Roalf (2016) had 87.2 sensitivity and 72.1 specificity at its optimal cut-off score. The Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) are the most commonly used scales to detect mild cognitive impairment (MCI) in population-based epidemiologic studies. Results MoCA scores were converted to MMSE-2 scores according to a conversion table that. At the optimal cut-off score of <25, the original MoCA demonstrated 84.4 sensitivity and 76.4 specificity. Then, we evaluated the reliability and accuracy of this algorithm to convert the MoCA to the MMSE-2. The MoCA’s memory testing involves more words, fewer learning trials, and a longer delay before recall than the MMSE. Among the participants with higher education, only the variant by Roalf (2016) had similar AUC to the original MoCA.
Executive functions, higher-level language abilities, and complex visuospatial processing can also be mildly impaired in MCI participants of various etiologies and are assessed by the MoCA with more numerous and demanding tasks than the MMSE. Er wurde 2005 von einer Gruppe an der McGill-Universität veröffentlicht, die mehrere Jahre lang an Gedächtniskliniken in Montreal gearbeitet hat. MoCA was developed in a memory clinic setting and normed in a highly educated population. Das Montreal Cognitive Assessment (Montreal Cognitive Assessment, MoCA) ist ein kurzer Test mit 30 Fragen, der etwa 10 bis 12 Minuten dauert und bei der Beurteilung von Menschen mit Demenz hilft.
